Abstract
The 2019 coronavirus disease (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) has posed a considerable challenge to global healthcare. Acute interstitial nephritis (AIN) post SARS-CoV-2 infection and vaccination has been reported, but its clinical features and pathogenesis remained unclear. We reviewed so far the largest 22 cases of AIN post SARS-CoV-2 infection and 36 cases of AIN following COVID-19 vaccination. The onset of AIN was mainly related to messenger RNA vaccines (52.8%). Apart from fever, proteinuria (45.5%) was the main manifestation of AIN post SARS-CoV-2 infection, left acute kidney injury (AKI, 63.9%) in patients post COVID-19 vaccination. The potential mechanism of vaccination induced AIN was conjugating vaccines with proteins to form a hapten, which activated dendritic cells and promoted a cascade immunological reaction leading to AIN.

Abstract
Infectious diseases are commonly implicated as potential initiators of autoimmune diseases (ADs) and represent the most commonly known factor in the development of autoimmunity in susceptible individuals. Epidemiological data and animal studies on multiple ADs suggest that molecular mimicry is one of the likely mechanisms for the loss of peripheral tolerance and the development of clinical disease. Besides molecular mimicry, other mechanisms such as defects in central tolerance, nonspecific bystander activation, epitope-determinant spreading, and/or constant antigenic stimuli, may also contribute for breach of tolerance and to the development of ADs. Linear peptide homology is not the only mechanism by which molecular mimicry is established. Peptide modeling (i.e., 3D structure), molecular docking analyses, and affinity estimation for HLAs are emerging as critical strategies when studying the links of molecular mimicry in the development of autoimmunity. In the current pandemic, several reports have confirmed an influence of SARS-CoV-2 on subsequent autoimmunity. Bioinformatic and experimental evidence support the potential role of molecular mimicry. Peptide dimensional analysis requires more research and will be increasingly important for designing and distributing vaccines and better understanding the role of environmental factors related to autoimmunity.

Abstract
OBJECTIVES The hepatitis B vaccine comprises hepatitis B surface antigen (HBsAg) produced by transgenic yeast cells. There are few serious adverse events (SAE) reports after Hepatitis B vaccination. METHODS The authors searched the Chinese legal documents database for all SAE with Hepatitis B vaccination from January 2010 to January 2022. RESULTS All seven patients received yeast-derived recombinant hepatitis B vaccine. Three cases of myocarditis (death), 2 cases of interstitial pneumonia (death), and 2 cases of encephalitis. The mean time of onset of SAE was 8.3 ± 4.3 h after vaccination. CONCLUSION The mechanism of vaccine-induced myocarditis may come from immune protein reactions. Based on the experience of Hepatitis B vaccine adverse events, we present new insights into the mechanism of myocarditis caused by the COVID-19 vaccine.

Abstract
Since the early 1800s vaccines have saved numerous lives by preventing lethal infections. However, during the past two decades, there has been growing awareness of possible adverse events associated with vaccinations, cultivating heated debates and leading to significant fluctuations in vaccination rates. It is therefore pertinent for the scientific community to seriously address public concern of adverse effects of vaccines to regain public trust in these important medical interventions. Such adverse reactions to vaccines may be viewed as a result of the interaction between susceptibility of the vaccinated subject and various vaccine components. Among the implicated mechanisms for these reactions is molecular mimicry. Molecular mimicry refers to a significant similarity between certain pathogenic elements contained in the vaccine and specific human proteins. This similarity may lead to immune crossreactivity, wherein the reaction of the immune system towards the pathogenic antigens may harm the similar human proteins, essentially causing autoimmune disease. In this review, we address the concept of molecular mimicry and its application in explaining post vaccination autoimmune phenomena. We further review the principal examples of the influenza, hepatitis B, and human papilloma virus vaccines, all suspected to induce autoimmunity via molecular mimicry. Finally, we refer to possible implications on the potential future development of better, safer vaccines.

Abstract
Vaccination is a safe and effective approach to prevent deadly diseases. To increase vaccine production, we propose that a mechanical stimulation can enhance protein production. In order to prove this hypothesis, Sf9 insect cells were used to evaluate the increase in the expression of a fusion protein from hepatitis B virus (HBV S1/S2). We discovered that the ultrasound stimulation at a frequency of 1.5 MHz, intensity of 60 mW/cm2, for a duration of 10 minutes per day increased HBV S1/S2 by 27%. We further derived a model for transport through a cell membrane under the effect of ultrasound waves, tested the key assumptions of the model through a molecular dynamics simulation package, NAMD (Nanoscale Molecular Dynamics program) and utilized CHARMM force field in a steered molecular dynamics environment. The results show that ultrasound waves can increase cell permeability, which, in turn, can enhance nutrient / waste exchange thus leading to enhanced vaccine production. This finding is very meaningful in either shortening vaccine production time, or increasing the yield of proteins for use as vaccines.

Abstract
Hepatitis B is an infectious liver disease and vaccination is an effective way to protect individuals. We have applied mechanical wave stimulation to increase protein production. To validate our design, we used Sf9 insect cells to increase antigen fragment fusion protein expression for hepatitis B virus (HBV S1/S2). We discovered that stimulation at a frequency of 1.5 MHz, intensity of 60 mW/cm(2), for a duration of 10 minutes per day increased HBV S1/S2 production by 15%. This finding is very significant for shortening vaccine production time or increasing the yield of proteins for use as vaccines.

Abstract
BACKGROUND Influenza vaccines produced in embryonated eggs might pose a risk to patients with egg allergy. However, patients experiencing influenza vaccine-associated anaphylaxis (IVA) do not always have egg allergy. In the 2011-2012 season, an unusually high incidence of IVA was reported in Japan. OBJECTIVE We sought to identify the cause of the increase in anaphylactic events in 2011-2012 in Japan. METHODS We collected blood specimens from patients with IVA from all areas of Japan. We analyzed 19 patients with confirmed IVA and 25 age-matched control subjects, including 10 with egg allergy who had no adverse events after corresponding vaccination. ELISA was used to measure specific IgE levels to the trivalent vaccines of several manufacturers and hemagglutinin proteins derived from both egg and cell cultures. Antigen-induced basophil activation was evaluated by measuring CD203c expression by means of flow cytometry. Vaccine excipients were also examined for effects on CD203c expression. RESULTS None of the patients with IVA had severe egg allergy. Levels of specific IgE antibodies to influenza vaccine antigens, whole-vaccine products from different manufacturers, and hemagglutinin proteins (A H1, H3, and B) derived from both egg and cell cultures were significantly increased in patients with IVA compared with those in control subjects. Influenza vaccine-induced CD203c expression in basophils was also highly enhanced in patients with IVA but not in control subjects. Because IVA was most frequent in patients who received 2-phenoxyethanol (2-PE)-containing vaccine, the effect of this preservative on basophil activation was examined, and the activation was slightly enhanced by 2-PE but not thimerosal. CONCLUSIONS The 2011-2012 IVA spike in Japan was caused by specific IgE antibodies to influenza vaccine components. Excipients could not be implicated, except for a modest effect of 2-PE.

Abstract
OBJECTIVES All pharmacologic agents have the potential for both benefit and toxicity. Among the more interesting and important adverse consequences of drug therapy are a range of joint and connective tissue complaints that may mimic or reproduce primary rheumatologic diseases. In this article, we review the literature on commonly used drugs reported to induce arthritis and/or connective tissue-based diseases. We assess the strength of the reported associations, discuss diagnostic features and treatment implications, and consider possible mechanisms for drug-induced genesis of rheumatic conditions. METHODS We reviewed the Medline database from 1987 to 2006 to identify drug-induced arthritic and connective-tissue disease syndromes, utilizing 48 search terms. A qualitative review was performed after the articles were abstracted and the relevant information was organized. RESULTS Three hundred fifty-seven articles of possible relevance were identified. Two hundred eleven publications were included in the final analysis (case series and reports, clinical trials, and reviews). Many drugs were identified as mimicking existing rheumatic conditions, including both well-established small molecules (eg, sulfasalazine) and recently introduced biologic agents (eg, antitumor necrosis factor agents). The most commonly reported drug-induced rheumatic conditions were lupus-like syndromes. Arthritis and vasculitis were also often reported. CONCLUSIONS Drug-induced rheumatic syndromes are manifold and offer the clinician an opportunity to define an illness that may remit with discontinuation of the offending agent. Early diagnosis and withdrawal of the drug may prevent unnecessary morbidity and disability.

Abstract
Hepatitis B virus (HBV) vaccination has been implicated as a potential trigger for autoimmune diseases but there are no prospective studies in lupus. We therefore assessed prospectively the safety and efficacy of immunization with recombinant DNA HBV vaccine (Euvax B; LG Life Sciences) in systemic lupus erythematosus (SLE) patients. Twenty-eight consecutive inactive SLE patients [Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) <4], age between 18 and 50 years and negative serology for HBV, were selected. Exclusion criteria were prednisone >/=20 mg/day and immunosuppressive drugs. Clinical and laboratorial assessments were obtained at study entry and one month after the three doses. In addition, a previous one year evaluation was performed using a standard electronic protocol. The mean age was 34 +/- 7.7 years and disease duration was 10.4 +/- 6.7 years. An adequate seroconversion was achieved at the end of the study (93%), although a lower frequency after the first (4%) and second dose (54%) was observed. No significant change in mean SLEDAI score was detected after each dose throughout the study (0.14 +/- 0.52 versus 0 versus 0.61 +/- 1.66 versus 0.36 +/- 1.34, P = 0.11). Reinforcing these findings, the 11% flares during vaccination was similar to the 21% observed in the previous year (P = 0.46). Furthermore, the mean prednisone dose at study entry was comparable to the end of the study (2.86 +/- 3.06 versus 4.64 +/- 8.25 mg/day, P = 0.32). In addition, the frequency of immunosuppressive therapy during the vaccination period (11%) was alike to the 14% observed in the previous year before entry (P = 0.66). Hepatitis B vaccination was safe in inactive SLE patients with an adequate vaccine response rate.

Abstract
Chronic fatigue syndrome (CFS) is thought to have a worldwide prevalence of 0.4-1% with approximately 240,000 patients in the UK. Diagnosis is based on clinical criteria and critically depends on exclusion of other physical and psychiatric diseases. Studies of pathogenesis have revealed immune system abnormalities and chronic immune activation, dysfunction of the hypothalamic-pituitary-adrenal (HPA) axis, brain abnormalities, evidence of emotional stress (comprising host aspects) and evidence of exogenous insults, for example, various microbial infections (Epstein-Barr virus, enteroviruses, parvovirus B19, Coxiella burnetii and Chlamydia pneumoniae), vaccinations and exposure to organophosphate chemicals and other toxins (comprising environmental aspects). Emotional stress appears to be very important as it reduces the ability of the immune system to clear infections, it's presence has been shown to determine whether or not an individual develops symptoms upon virus infection, and it leads to activation of the HPA axis. But, emotional stress is distinct from depression, the presence of which precludes a diagnosis of CFS. There is no specific treatment for CFS other than the much underutilised approach of specific treatment of virus infections. Current priorities are to understand the molecular pathogenesis of disease in terms of human and virus gene expression, to develop a diagnostic test based on protein biomarkers, and to develop specific curative treatments.

Abstract
PURPOSE Rare and unexpected adverse events following hepatitis B immunization have been reported. This article aims to illustrate the risk-benefit assessment of hepatitis B immunization strategies, using the available evidence in medical literature. CURRENT EVENTS i) Hepatitis B vaccination efficacy is high in infants, children and adolescents. It may be lower in adults and at risk populations; ii) Hepatitis B descriptive epidemiological data in France are scarce, fragmental, unprecise and changing according to the studied population strata. The incidence of symptomatic cases in the general population is below 5 per 100,000 since the year 2000. In France, it is estimated that about 300,000 adults are carriers of HBs antigen, and thus able to transmit the disease; iii) The actual French pharmacovigilance signal and the epidemiological studies may suggest the hypothesis of an association between the occurrence of central nervous system demyelinating diseases and hepatitis B vaccination. If this association exists, the relative risk is probably of less than 3. PERSPECTIVES The lack of accuracy of risks estimates complicates the risk-benefit assessment of hepatitis B vaccination. Its perception is then influenced and distorted by subjective factors, underlying the need for research in communication about benefits and risks of immunizations. Although still debated, the hypothesis of a putative role of hepatitis B vaccine in the pathophysiology of demyelinating diseases should prompt to pursue experimental and epidemiological research to better understand the links between infectious environment and inflammatory chronic diseases.

Abstract
Hepatitis B infection is one of the most important causes of acute and chronic liver disease. During the 1980s, genetically engineered hepatitis B vaccines (HBVs) were introduced in the United States. A large-series of serious autoimmune conditions have been reported following HBVs, despite the fact that HBVs have been reported to be "generally well-tolerated." A case-control epidemiological study was conducted to evaluate serious autoimmune adverse events prospectively reported to the vaccine adverse events reporting system (VAERS) database following HBVs, in comparison to an age, sex, and vaccine year matched unexposed tetanus-containing vaccine (TCV) group for conditions that have been previously identified on an a priori basis from case-reports. Adults receiving HBV had significantly increased odds ratios (OR) for multiple sclerosis (OR = 5.2, p < 0.0003, 95% Confidence Interval (CI) = 1.9 - 20), optic neuritis (OR = 14, p < 0.0002, 95% CI = 2.3 - 560), vasculitis (OR = 2.6, p < 0.04, 95% CI = 1.03 - 8.7), arthritis (OR = 2.01, p < 0.0003, 95% CI = 1.3 - 3.1), alopecia (OR = 7.2, p < 0.0001, 95% CI = 3.2 - 20), lupus erythematosus (OR = 9.1, p < 0.0001, 95% CI = 2.3 - 76), rheumatoid arthritis (OR = 18, p < 0.0001, 95% CI = 3.1 - 740), and thrombocytopenia (OR = 2.3, p < 0.04, 95% CI = 1.02 - 6.2) in comparison to the TCV group. Minimal confounding or systematic error was observed. Despite the negative findings of the present study regarding the rare serious adverse effects of HBVs, it is clear that HBV does, indeed, offer significant benefits, but it is also clear that chances of exposure to hepatitis B virus in adults is largely life-style dependent. Adults should make an informed consent decision, weighing the risks and benefits of HBV, as to whether or not to be immunized.

BACKGROUND Hepatitis B virus (HBV) causes acute and chronic liver diseases. Hepatitis B vaccination is recommended for health-care workers. OBJECTIVES To assess the beneficial and harmful effects of hepatitis B vaccination in health-care workers. SEARCH STRATEGY We searched the trial registers of The Cochrane Hepato-Biliary Group, The Cochrane Library, MEDLINE, and EMBASE to February 2003. SELECTION CRITERIA Randomised trials comparing any dose, injection route, injection site, or schedule of hepatitis B plasma-derived vaccines (PDV) or recombinant vaccines (RV) versus placebo, no intervention, or another hepatitis B vaccine in health-care workers. DATA COLLECTION AND ANALYSIS Two reviewers extracted the data independently. The reviewers assessed the methodological quality of the trials regarding generation of the allocation sequence, allocation concealment, double blinding, and follow-up. The results were presented as relative risk (RR) with 95% confidence intervals (CI). MAIN RESULTS We identified 21 randomised trials, all with one or more methodological weaknesses. Four trials demonstrated that PDV versus placebo significantly decreased hepatitis B events at maximum follow-up (RR 0.51, 95% CI 0.35 to 0.73). RV did not differ significantly from PDV in eliciting a protective hepatitis B surface antibody (anti-HBs) level in two trials. Both vaccines were well tolerated. Low-dose vaccine (1 or 2 microg) by the intradermal route resulted in significantly more participants without protective anti-HBs level compared with high-dose (10 or 20 microg) by the intramuscular route (RR 1.41, 95% CI 1.13 to 1.76). The intradermal route caused significantly more local adverse events, while the intramuscular route caused significantly more systemic adverse events. The gluteal injection produced significantly more participants without protective anti-HBs level than the deltoid injection. The prevalence of anti-HBs seroconversion by rapid vaccination (0, 1, and 2 months) was significantly lower than that by standard vaccination (0, 1, and 6 months). Booster vaccinations with different RV doses (2.5, 5, 10, 20, or 40 microg) produced similar prevalence of anti-HBs seroconversion in three trials assessing participants who did not respond to previous HBV vaccination. AUTHORS' CONCLUSIONS PDV significantly prevents hepatitis B events. RV seems to be able to elicit similar protective anti-HBs levels. The intramuscular route with 20 microg RV was significantly more effective compared with the intradermal route with 2 microg RV as was the standard schedule compared with a rapid schedule and deltoid intramuscular injection compared with the gluteal intramuscular injection. It is unclear if booster vaccination of non-responders offers higher anti-HBs seroconversion and hepatitis B vaccine prevents the infection of hepatitis B mutants in health-care workers.

Abstract
The preparation of recombinant hepatitis B vaccines involves using cellular cultures of Saccharomyces cerevisiae, otherwise known as baker's yeast. Prior to vaccine licensure, clinical trials were performed to address whether residual yeast proteins in the vaccines could induce anaphylaxis, including testing for IgE anti-yeast antibody levels. 1-2% of subjects had anti-yeast IgE antibodies before immunization, but demonstrated no significant rise in IgE after HBV. We searched reports in the Vaccine Adverse Event Reporting System (VAERS) for those that mentioned a history of allergy to yeast and then reviewed the adverse events described in these reports for potential anaphylactic reactions. Probable anaphylaxis was defined as the presence of one or more dermatologic symptoms and one or more respiratory, gastrointestinal, or cardiovascular symptoms with onset within 4 h of Hepatitis B vaccination. Possible anaphylaxis was defined in one of two ways: (1) cases that described dermatologic or respiratory symptoms (but not both) occurring within 4h of vaccination; or (2) cases that described one or more dermatologic and/or respiratory symptoms occurring 4-12 h post vaccination. Among the 107 reports of pre-existing "yeast allergies," 11 reports described probable or possible anaphylaxis after HBV. Four additional cases were described after other vaccines. The majority of vaccinees who met the case definitions and had a history of yeast allergies were female, ages ranged from 10 to 64, and symptom onset ranged from 15 min to 5 h after vaccination. No deaths were reported. The small number of reports to VAERS may be partly due to health care professionals observing current contraindications by not vaccinating yeast sensitive individuals. Nevertheless, yeast associated anaphylaxis after HBV in sensitized patients appears to be a rare event.

Abstract
Studies indicate that roughly half of health care workers are not immunized against hepatitis B and influenza. Findings from a survey of 1,000 registered nurses (RNs) conducted to analyze their beliefs and actions related to immunization recommendations are reported. Only 8% of the responding RNs chose not to receive vaccination against hepatitis B. The primary reasons that nurses declined hepatitis B vaccination were because they were not working in nursing or did not believe they were at risk of exposure. Similarly, 86% of the RNs reported they had ever received a flu shot, and 69% reported of being immunized during 2 of the previous 4 years. Rationale for receiving immunization included belief in its effectiveness, belief that they were at risk of exposure, and that it was provided free of charge. Reasons for declining included concerns about side effects, lack of concern about getting the illness, and doubts about effectiveness. The nurses who responded to the survey appear to value immunizations and generally adhere to immunization recommendations. Further study needs to be conducted on related issues, including follow-up for assessment of long-term protection of hepatitis B immunization and adherence to guidelines for postexposure prophylaxis. Ongoing monitoring and further study of serious complications of hepatitis B immunizations are also needed.

Abstract
OBJECTIVE This study compares the seroconversion rate after vaccination with genetically derived and plasma pooled vaccine in normal healthy adult volunteers. POPULATION AND METHODS Forty volunteers of either sex were randomly divided into two groups comprising equal numbers of subjects. The mean (+/- SD) age and weight of the subjects in group A were 27.52 +/- 3.48 years and 65.60 +/- 8.06kg, respectively, while the mean (+/- SD) values for the individuals in group B were 30.75 +/- 3.78 years and 68.55 +/- 6.59kg. Recombinant and plasma pooled vaccines were administered as single 20 microg and 3 microg intramuscular injections to the respective groups of volunteers on days 1, 30, and 180. An automated system (AxSYM, based on microparticle enzyme immunoassay) was used to measure the seroconversion rate in serum harvested from an 8 mL blood sample collected within 1 month of the third dose (i.e., on day 210), from each volunteer. RESULTS Both of the vaccines were well tolerated by all individuals and no adverse reaction was reported or observed during the study. The subject seroconversion rate corrected with reference to the cut-off rate after vaccination with DNA-derived vaccine was significantly greater (p < 0.05) than that observed after the administration of plasma pooled-derived vaccine (51.64 +/- 17.00 versus 22.96 +/- 12.04). CONCLUSION The vaccine response, as indicated by the seroconversion rate (concentration of anti-HBs in mIU/mL) in the group vaccinated with genetically derived vaccine was observed to be better (p < 0.01) when matched with the International Antibody Standard.

Abstract
Reports of multiple sclerosis developing after hepatitis B vaccination have led to the concern that this vaccine might be a cause of multiple sclerosis in previously healthy subjects. Some articles evidenced that minor Hepatitis B virus (HBV) polymerase proteins could be produced by alternative transcriptional or translational strategies. Their detection is very difficult because they are in minute concentration and probably enzymatically inactive, however, it was shown that they could be exposed on the outside of the virus particles and also be immunogenic. In addition, HBV polymerase shares significant amino acid similarities with the human myelin basic protein. We hypothesise that some of the apparent adverse reactions to the vaccine could be due to a process called of molecular mimicry, the HBV polymerase, which could be a contaminant in the recombinant or plasma-derived vaccines, could act as autoantigens and induce autoimmune demyelinating diseases such as multiple sclerosis.

Abstract
The aim of this work is to propose a method to search for a possible antigenic community between hepatitis B vaccine components and some auto-antibodies produced in rare patients with an autoimmune disease discovered few weeks or months after a hepatitis B vaccine injection. A 12-year-old girl showed symptoms of transverse myelitis 2 months after a hepatitis B vaccine booster injection. Later, high titers of antinuclear antibodies were found and a diagnosis of neurolupus was established. One serum was then mixed with various concentrations of hepatitis B vaccine. The antinuclear antibodies were totally absorbed at the highest concentration of vaccine, but not by the lowest. Anti-HBs specific antibodies were absorbed by all concentrations of vaccine. The results of this single preliminary experiment (which as to be repeated for other patients, and with large control studies) cannot establish a cross relationship. But it seems that this approach requires to be explored with some improvements. It could also incite us to use lower dosages of HBs antigen in the vaccine and to use the subcutaneous route of injection (to get lower titers of antibodies and to allow a slower diffusion of the antigen).

Abstract
BACKGROUND There have been no population-based studies of the potential association between neonatal death and newborn immunization with hepatitis B vaccine (HBV). METHODS As part of the Vaccine Safety Datalink Project, we defined a birth cohort at Southern and Northern California Kaiser Permanente Health Plans of more than 350,000 live births from 1993 to 1998 and ascertained all deaths occurring under 29 days of age. We compared the proportions of deaths among birth HBV-vaccinated and unvaccinated newborns and reviewed the causes and circumstances of their deaths. We performed detailed clinical reviews of all HBV-vaccinated neonates who died and a sample of unvaccinated neonates who died and who were matched to vaccinated deaths for days of life, sex, birth year and site of care. To avoid confounding, we categorized the causes of death as either "expected" or "unexpected" and performed a stratified analysis to compare mortality with immunization status. RESULTS There were 1363 neonatal deaths during the study period. Whereas 67% of the entire birth cohort received HBV at birth, only 72 (5%) of the neonates who died were HBV-vaccinated at birth (P < 0.01). We found no significant difference in the proportion of HBV-vaccinated (31%) and unvaccinated (35%) neonates dying of unexpected causes (P = 0.6). Further we could not identify a plausible causal or temporal relationship between HBV administration and death for the 22 vaccinated neonates who died unexpectedly. CONCLUSIONS A relationship between HBV and neonatal death was not identified.

Abstract
SPf66 is a synthetic malaria peptide vaccine, which has been widely tested in combination with aluminium hydroxide (alum) as the adjuvant. Since this formulation is weakly immunogenic, we sought to improve its immunogenicity by using the saponin adjuvant QS-21. SPf66/QS-21 vaccines were evaluated for safety, tolerability and immunogenicity in healthy adults. The vaccines were found to be safe in 87/89 (97.8%) volunteers studied. However, two individuals developed severe vaccine allergy following the third dose of 1/3 SPf66/QS-21 formulations tested. Vaccine formulations containing QS-21 induced a 45- to over 200-fold increase in anti-SPf66 IgG titres over the alum formulation after the second and third doses, respectively. Anti-SPf66 antibody from some subjects reacted against asexual blood stage parasites, as demonstrated by immunofluorescence and immunoblotting. Antibody responses generated by the QS-21 formulations were of longer duration compared to those evoked by the alum formulation. While SPf66/alum has been found to induce only CD4+ T cell response, the QS-21 formulations exhibited the potential to also elicit SPf66-specific CD8+ responses. These observations demonstrate that the use of QS-21 can substantially enhance the immunogenicity of peptide vaccines, such as SPf66.

Abstract
The author consider some questions to be more carefully studied about the hepatitis B vaccine: route of injection (subcutaneous or intramuscular), amount of antigen (Ag), adjuvant (necessary or not), antigenic and molecular structure of HBsAg. What is important is to get high seroconversion rates, but not to get very high antibody titers (protective immunity is not dependent of antibody titers). Two types of vaccine could be used, and further studied. Why not use in healthy adults and children low dose vaccines (with 1.5-2.5 microg of HBsAg), possibly without adjuvant, and to be injected subcutaneously? And the 20 microg dose of vaccine could be used intramuscularly only for low- or non-responders, in high risk groups.

Abstract
BACKGROUND Recent studies have suggested that adult hepatitis B vaccination may be associated with adverse reactions. OBJECTIVE To further examine the relative risk, percentage association, and statistical significance of arthritic, immunologic, and gastrointestinal adverse reactions reported after adult hepatitis B vaccination compared with control vaccines. DESIGN The Vaccine Adverse Events Reporting System (VAERS) database was analyzed for the incidence of adverse reactions after adult hepatitis B immunization compared with the incidence of adverse reactions reported to VAERS about vaccine control groups. SETTING The medical and scientific communities have generally accepted that hepatitis B vaccine, a highly purified, genetically engineered single-antigen vaccine, is a safe vaccine. METHODS The VAERS database was analyzed from 1997 to 2000 for adverse reactions associated with adult hepatitis B vaccination and from 1991 to 2000 for adverse reactions reported about vaccine control groups. RESULTS The results showed a statistically significant increase in the incidence of adverse reactions reported after adult hepatitis B vaccination when compared with the incidence of adverse reactions reported to VAERS about control vaccines. CONCLUSIONS Patients and physicians need to be fully informed of the potential adverse reactions associated with hepatitis B vaccination so that together they can make an informed consent decision about the risk versus the benefit. Patients who may have had an associated adverse reaction to hepatitis B vaccine should be made aware that they may be eligible for compensation from the no-fault Vaccine Compensation Act, administered by the US Court of Claims.

Abstract
The recent decision by the French government to compensate 3 recipients of hepatitis B vaccine preceding the onset of multiple sclerosis presumes a possible causal link and brings into question the use of current rules of causality assessment. Available evidence does not support a causal link or is equivocal but the accuracy of current methods of vaccine surveillance should be urgently improved. Larger and longer randomised trials, updated summaries of evidence, linked databases, prospective vaccination registers, bar-coding of vaccines and standardisation of adverse event definitions are possible measures to address current problems.

Abstract
We report on a 36-year-old man who developed an inflammatory polyradiculoneuropathy similar to Guillain-Barré syndrome 9 days after hepatitis B vaccination. Extensive immunotherapy including immunoglobulins, steroids, plasmapheresis, cyclophosphamide and methotrexate did not stop the progressive course of the disease and the patient died 4 months later due to multiorgan failure with septic shock symptoms and adult respiratory distress syndrome (ARDS).The neuropathological investigation showed severe axonal loss with mild demyelination of peripheral nerves and mononuclear cell infiltrates, predominantly T-lymphocytes, in nerve roots and spinal ganglia. In addition, there were unusual, perivascular and parenchymal lymphocytic cell infiltrates in the grey matter, especially the anterior horns of the spinal cord. The temporal relationship to hepatitis B vaccination, the strong increase of HBs-antibodies within 3 weeks after vaccination, and the presumptive immune mediated pathology of this disorder suggest a possible etiologic link with hepatitis B vaccine.

Abstract
On exposure to a pathogen, a host may resist infection, become subclinically infected, or progress through several stages from mild to severe infection. Chronic sequelae may or may not occur. Host factors, particularly host genes, influence many of these stages. We have used a model of the continuum of pathogenesis of infectious diseases to consider the effect of host genes on five pathogens of significant public health burden: Mycobacterium tuberculosis, Plasmodium species, human immunodeficiency virus, hepatitis B virus, and Vibrio cholerae. The relationships between these infections and polymorphisms in human leukocyte antigen, cytokines, other immune response, or pathogen receptor genes are reviewed. We discuss gene-gene interactions and their effects in complex settings, such as coinfections with several pathogens. Priorities for prevention and control of these pathogens include vaccines and antimicrobial drugs. Research on how host genes can influence vaccine responses and the efficacy of drugs or other interventions, as well as further research into the relationship of host genes to infectious disease outcomes, may lead to new strategies for prevention and control.

Abstract
The challenge of viral hepatitis has been acknowledged and confronted in the last decade. Significant progress in prevention of infection with HAV and HBV may eradicate these serious infections from the United States and other parts of the world in the coming decades. Application of prophylactic strategies to children will be a major mechanism in accomplishing this task. The quest for potent antiviral medications continues. The next critically important development will be ways to prevent new HCV infections and to treat the millions of already infected individuals at risk for the serious consequences of this disease. For pediatricians, realizing these goals requires a greater understanding of perinatal HCV transmission, use of vaccines for prevention of viral hepatitis, and identification of HCV-infected children who are likely to benefit from new therapeutic strategies as they become available.

Abstract
Immunisations have been one of the most cost-effective public health interventions in human history. Despite remarkable progress, several challenges face immunisation programs worldwide. Paradoxically, despite vaccines' clear effectiveness in reducing risks of diseases that were previously widely prevalent and caused substantial morbidity and mortality, current vaccination policies have become increasingly controversial due to concerns about vaccine safety. Vaccines, like other pharmaceutical products, are not entirely risk-free. While most known adverse effects are minor and self-limited, some vaccines have been associated with very rare but serious adverse effects. Because such rare effects are often not evident until vaccines come into widespread use, ongoing surveillance programs to monitor vaccine safety are needed. Such monitoring will be essential if the public is to accept the increasing number of new vaccines made possible by biotechnology. The interpretation of data from vaccine safety research is complex and is associated with some uncertainty. Effectively communicating this uncertainty and continuing to improve understanding of rare risks and risk factors are essential for "mature" immunisation programs to maintain public confidence in immunisations.

Abstract
Zona pellucida (ZP) glycoproteins contain numerous antigenic determinants including carbohydrate, protein, and conformational epitopes; and the immunogenicity of these complex glycoproteins varies in different mammalian hosts. Studies have now shown that antibodies from primates immunized with a cDNA-expressed recombinant rabbit ZP protein (the homologue of the human ZP1 [hZP1]) inhibit sperm binding to the ZP without altering ovarian function, unlike immunization with ZP3 and ZP2 protein families. The ZP1 protein or peptides derived from it (recombinant or synthetic) are therefore primary candidates for use in designing safe and reversible human and animal contraceptive vaccines. In order to define peptide epitope(s) that may be critical for eliciting an immune response sufficient to effect immunological contraception without causing any adverse effects on ovarian physiology, studies have been carried out to identify immunodominant B-cell epitopes of the ZP1 protein. The amino acid sequence of the hZP1 was used to design a set of 94 (15-mer) biotinylated peptides having an overlap of 9 amino acids. Using these peptides in a modified enzyme-linked immunoassay, antibodies in sera from rabbits or baboons immunized with native porcine ZP protein were screened for ZP1 peptide recognition. These studies demonstrate that there are a limited number of peptides recognized by primate antibodies but that the overlapping peptides sharing the sequence GPLTLELQI are recognized by both rabbit and baboon antibodies regardless of the adjuvant system used to induce the immune response. This peptide is 100% conserved in amino acid sequence between the human and pig, although the rabbit protein has two conserved amino acid substitutions (100% similar, 77% identical). Because this peptide is immunogenic as well as antigenic in primates, it could play a major role in the development of human contraceptive vaccines.
