Abstract
People living with human immunodeficiency virus (HIV) are at higher risk of morbidity and mortality due to vaccine-preventable diseases. At the same time, they are less likely to respond to vaccinations, and might have a higher rate of vaccine adverse event and faster waning of protective effect. International and national guidelines emphasize the importance of vaccinating people living with HIV against respiratory system disease pathogens including seasonal influenza, Streptococcus pneumoniae, and COVID-19, as well as against sexually transmitted infections, i.e., Hepatitis A and B (HAV, HBV) and human papillomavirus (HPV). This narrative review aims to provide a comprehensive examination of the current knowledge regarding the immune and clinical responses elicited by vaccinations in the older adult population living with HIV.

Evaluation of effectiveness, safety and cost-benefit of the 23- valent pneumococcal capsular polysaccharide vaccine for HIV-Infected patients. Vaccine 2022; 40:37-42. [PMID: 34857419 DOI: 10.1016/j.vaccine.2021.11.058] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 11/01/2021] [Accepted: 11/19/2021] [Indexed: 11/23/2022]
Abstract
INTRODUCTION Due to the lack of understanding of the protective effects and safety of 23-valent pneumococcal polysaccharide vaccine (PPV23) in immune-deficient populations, the vaccination rate of PPV23 among HIV-infected patients is still very low in China. The main objectives of this study were to determine whether the efforts to assess measures for the prevention of pneumococcal pneumonia are still worthwhile, and provide designated vaccination program of HIV-infected persons for government policy based on. METHODS 60 HIV-infected adults in Lanshan county who had never been vaccinated with any pneumococcal vaccine were enrolled in this study, voluntary vaccination of PPV23 and One-year follow-up after vaccination can be completed. RESULT 76.67% patients (46/60) had serologic response at 12 months after vaccine, CD4 count(≤500 cells/ul or > 500 cells/ul) and Month from diagnosis to first antiviral therapy (≤1 month or > 1 month) were related to antibody responses (p < 0.05).In this study, PPV23 was well tolerated, no adversereaction was reported.11 Streptococcus pneumoniae pneumonia (9.17%,11/120) occurred in the Unvaccinated group and 1 case(1.67%,1/60)in the vaccination group within one year after vaccination(Fisher's exact probability, P = 0.225). The VE was 81.79%. The per capita benefit was 39.32 dollars, thebenefit-costratio = 1.19. There are significant statistical differences between the vaccinated group and the non-vaccinated group in outpatient costs (p < 0.05, 95 %CI: 9.29-32.11), Medicine costs (p = 0.017, 95 %CI: 2.47-24.44), and disease related indirect costs (p = 0.038, 95 %CI: 0.93-33.63) within one year of vaccination. CONCLUSION Our study results showed that PPV23 can be safely and effectively administered to HIV-1 infected individuals and effectively preventing Streptococcal pneumonia. Considering the cost-benefit of vaccination among HIV-infected persons, as it has been reported in our study, it is necessary to promote the widespread use of the vaccine among HIV-infected persons in the future.

EClinicalMedicine 2020; 29-30:100576. [PMID: 33294820 PMCID: PMC7695973 DOI: 10.1016/j.eclinm.2020.100576] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Revised: 09/15/2020] [Accepted: 09/18/2020] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND The objective of this systematic review and meta-analysis was to summarise the literature regarding the immunogenicity of pneumococcal conjugate vaccines (PCV) and pneumococcal polysaccharide vaccines (PPSV) in adult people living with HIV (PLWH) in the era of advanced combination antiretroviral therapy (cART). METHODS The systematic review protocol was published online (PROSPERO ID: CRD 42020153137). We searched Medline (Ovid), EMBASE (Ovid), and the Global Health Library for publications from 2000 to June 11, 2020. We included all studies in adult PLWH that reported vaccine immunogenicity outcomes. The primary outcome was seroconversion rate (SCR) after PCV, PPSV and PCV/PPSV combined. For random-effects meta-analysis, we included studies defining SCR as a ≥ 2-fold increase in IgG from baseline, and reporting SCR for serotypes 6B, 14, or overall SCR, 1-3 months after vaccination. FINDINGS Our search identified 1597 unique studies, of which 115 were eligible for full-text assessment. Of these, 39 met the inclusion criteria (11 RCTs; 28 cohort studies). A high degree of heterogeneity was observed. Nineteen studies were included in the meta-analysis. Pooled overall SCRs were 42% (95% CI 30-56%), 44% (95% CI 33-55%) and 57% (95% CI 50-63%) for PLWH who received PPSV, PCV or a combination of PCV/PPSV, respectively. Compared to PPSV alone, a combination of PCV/PPSV yielded higher SCRs (OR 2.24 95% CI 1.41- 3.58), whereas we did not observe a significant difference in SCR between PCV and PPSV23 alone. There were no statistically significant differences in geometric mean post-vaccination antibody concentrations between vaccination schedules. Vaccination at higher CD4 cell counts improved immunogenicity in 8/21 studies, especially when PCV was administered. No studies assessed the long-term immunogenicity of PCV followed by PPSV23. Quality of evidence ranged from poor (n = 19) to good quality (n = 7). A limited number of pneumococcal serotypes was assessed in the majority of studies. INTERPRETATION We show that the recommended immunisation schedule consisting of a combination of PCV13/PPSV23, is immunogenic in PLWH in the era of advanced cART. However, the durability of this vaccination schedule remains unknown and must be addressed in future research. Vaccination with PCV should be delayed until immunological recovery (CD4>200) in recently diagnosed PLWH for optimal immunogenicity. The evidence gathered here supports wide implementation of the combination of PCV/PPSV23 for all PLWH. We recommend reassessment of this strategy once higher-valent PCVs become available. FUNDING HMGG is funded by a public research grant of ZonMw (project number 522004005).

Abstract
Human immunodeficiency virus (HIV) causes immune dysregulation, potentially affecting response to vaccines in infected persons. We investigated if unexpected adverse events (AEs) or unusual patterns of AEs after vaccination were reported among HIV-positive persons. We searched for domestic reports among HIV-positive persons to the Vaccine Adverse Event Reporting System (VAERS) during 1990–2016. We analyzed reports by age group (<19 and ≥19 years), sex, serious or non-serious status, live vaccine type (live versus inactivated), AEs reported, and CD4 counts. Of 532,235 reports received, 353 (0.07%) described HIV-positive persons, of whom 67% were aged ≥19 years, and 57% were male; most reports (75%) were non-serious. The most commonly reported inactivated vaccines were pneumococcal polysaccharide (27%) and inactivated influenza (27%); the mostly reported common live virus vaccines were combination measles, mumps, and rubella (8%) and varicella (6%). Injection site reactions were commonly reported (39%). Of 67 reports with CD4 counts available, 41 (61%) described persons immunocompromised at time of vaccination (CD4 count <500 cells/mm3), and differed from overall reports only in that varicella was the most common live virus vaccine (4 reports). Of 22 reports describing failure to protect against infection, 6 described persons immunocompromised at time of vaccination, among whom varicella vaccine was most common (3 reports). Of 66 reports describing live virus vaccines, 7 described persons with disseminated infection: 6 had disseminated varicella, 3 of whom had vaccine strain varicella-zoster virus. Of 18 reported deaths, 7 resulted from disseminated infection: 6 were among immunocompromised persons, 1 of whom had vaccine strain varicella-zoster virus. We identified no unexpected or unusual patterns of AEs among HIV-positive persons. These data reinforce current vaccine recommendations for this risk group. However, healthcare providers should know their HIV-positive patients’ immune status because immunocompromising conditions can potentially increase the risk of rare, but severe, AEs following vaccination with live virus vaccines.

Abstract
Humoral response to vaccination has been found to be inadequate in individuals infected with the human immunodeficiency virus (HIV). We retrospectively assessed antibody responses to three routinely recommended vaccines, against hepatitis B, hepatitis A and S. pneumoniae, in HIV-infected individuals. Data regarding age at HIV diagnosis, years of infection, sex, nationality, HIV mode of transmission, CD4 cell count, nadir CD4 count, plasma viral load, HIV stage, insurance status, educational level and treatment with Highly Active Antiretroviral Therapy (HAART) were collected. Univariate and multivariate analysis was performed in order to detect factors associated with response to vaccination. 437 patients were assessed for hepatitis B, 627 patients for hepatitis A and 66 patients for S. pneumoniae serologic vaccine responsiveness. Regarding hepatitis B and hepatitis A, education level and insurance status were the only predictors of response. As for S. pneumoniae vaccination HAART and control of viremia were correlated with better response to vaccination.

Abstract
U.K. guidelines for vaccinating HIV-infected adults against bacteria are based on limited data. We compared antibody responses between 211 HIV-infected and 73 HIV-uninfected adults vaccinated with pneumococcal polysaccharide vaccine (PPV) and Haemophilus influenzae b/meningococcal C polysaccharide-tetanus toxoid glycoconjugate vaccine (Hib/MenC-TT). IgG responses to Hib/MenC-TT were not significantly different. PPV induced median IgGs >1.3 μg/mL for 10/12 serotypes among HIV-uninfected participants and 5/12 in HIV-infected participants. HIV-uninfected adults had higher post-vaccination IgGs than HIV-infected adults for 4/12 serotypes (P < 0.001). Responses did not associate with CD4 count or viral suppression. In a U.K. HIV-infected population, Hib/MenC-TT induced similar responses to HIV-uninfected adults, whereas PPV induced poor responses.

Abstract
BACKGROUND Chronic HIV infection leads to severe perturbations of the B cell populations and hypo-responsiveness to vaccines. The associations between circulating B cell subpopulations and the antibody response to pneumococcal polysaccharide vaccine in antiretroviral-naïve and treated patients were studied. METHODS Sixty-six HIV-infected adults were grouped according to antiretroviral therapy (ART) and CD4+ cell count; 31 were ART-naïve and 35 were ART-treated, and they were matched for age, CD4 cell count, and duration of HIV infection. All subjects were immunized with the 23-valent polysaccharide vaccine against Streptococcus pneumoniae. Pre- and post-vaccination B cell subpopulations were assessed by flow cytometry. Serum IgG concentrations for vaccine serotypes were quantified by ELISA at baseline and at 4 and 48 weeks post-vaccination. RESULTS Patients under highly active antiretroviral therapy (HAART) had significantly higher antibody levels against pneumococcal vaccine antigens, while an adequate number of patients responded to vaccination. Memory B cells were diminished over time, although treated patients maintained higher levels of all subsets studied, with the exception of activated memory and isotype-switched memory B cells. CONCLUSIONS Low concentrations of total B cells and exhausted memory B cells was the strongest independent predictor of poor pneumococcal vaccine responsiveness, emphasizing that B cell subset disturbances are associated with a poor vaccine response among HIV-infected patients.

Abstract
BACKGROUND Several vaccines are recommended in HIV-infected patients due to an increased risk of vaccine-preventable infections, severe forms of the disease, or shared transmission routes. Few data are available regarding vaccination coverage and its determinants in this population. METHODS A cross-sectional study was performed in HIV-infected patients included in a hospital-based cohort in 2011. Vaccination coverage against hepatitis A virus (HAV), hepatitis B virus (HBV), seasonal and A(H1N1)2009 pandemic influenza, and invasive pneumococcal diseases (IPD) were recorded. Factors associated with vaccination were assessed by multivariate logistic regression. RESULTS 2467 patients were included (median age: 47 years; male gender 71.5%; men having sex with men (MSM): 43.9%; CDC stage C: 24.3%; HBV and/or hepatitis C virus co-infection: 14.4%). Median duration of HIV infection was 10 years and 93.1% of patients received combination antiretroviral therapy. At baseline, the median CD4 count was 527 cells/mm(3) and HIV viral load was <50 copies/mL in 83.3% of cases. Vaccination coverage for HBV, HAV, seasonal influenza, A(H1N1)2009 pandemic influenza, and IPD were 61.9%, 47.4%, 30.9, 48.3%, and 64.6%, respectively. Factors independently associated with vaccination were a younger (HBV) or an older age (influenza), male gender (HBV, HAV), MSM (HBV), CD4 count >200/mm(3) and HIV-RNA <50 copies/mL (IPD, influenza), longer duration of HIV infection (IPD, influenza), and follow-up by an experienced physician (HBV, IPD). CONCLUSIONS Vaccination coverage remained insufficient for all vaccine-preventable infections investigated in this study. Determinants for vaccination were largely not evidence-based, and efforts should be focused on improving physicians' knowledge about guidelines.

Abstract
BACKGROUND The objective of this study was to determine whether the 3-dose quadrivalent human papillomavirus (HPV) vaccine series (HPV-6, -11, -16, -18) is immunogenic and safe in young women infected with human immunodeficiency virus (HIV). METHODS We enrolled 99 women aged 16-23 years in a phase 2, open-label, multicenter trial, conducted from 2008 to 2011 by the Adolescent Medicine Trials Network for HIV/AIDS Interventions. Outcome measures were immunogenicity 4 weeks after dose 3, measured by (1) geometric mean titers (GMTs) and (2) seroconversion rates for HPV-6, -11, -16, and -18, among those seronegative and HPV DNA negative for each type. Immune responses were compared to those of a historical comparison group of HIV-negative women (n = 267) using univariate methods. Clinical and laboratory adverse events were assessed after each dose. RESULTS The mean age of subjects was 21.4 years; 80% were non-Hispanic black, 69 were not taking antiretroviral therapy (ART), and 30 were taking ART. No differences in GMTs were noted among participants taking ART vs the comparison group, but GMTs were lower in participants not taking ART vs the comparison group for HPV-16 (2393 vs 3892 milli-Merck units per milliliter [mMU/mL], P = .012) and HPV-18 (463 vs 801 mMU/mL, P = .003). Seroconversion rates were 100% for HPV-6, -11, -16, and -18 among participants taking ART. Rates ranged from 92.3% (for HPV-18) to 100.0% (for HPV-6) among participants not taking ART. One severe adverse event (fatigue) was noted. CONCLUSIONS In a sample of HIV-infected women who were HPV DNA and HPV seronegative, immune responses to HPV vaccination were generally robust and the vaccine was well tolerated.

Abstract
BACKGROUND Vaccination with 7-valent pneumococcal conjugate vaccine (PCV) has been shown to decrease the incidence of recurrent invasive pneumococcal disease among HIV-infected adults in Africa. Longitudinal follow-up studies of serologic responses to different doses of 7-valent PCV are rarely performed in HIV-infected adult patients receiving combination antiretroviral therapy (cART). METHODS From October 2008 to June 2010, 115 CD4-matched pairs of HIV-infected patients aged ≥ 20 years who had no prior pneumococcal vaccination received one or two doses of 7-valent PCV. Anticapsular antibodies against 4 serotypes (6B, 14, 19F, and 23F) were examined at the 12th, 24th, 36th, and 48th week following vaccination. Significant antibody responses were defined as ≥ 2-fold increase in the IgG level plus a post-vaccination antibody level ≥ 1000 ng/ml. RESULTS The most common reported adverse effects were injection site soreness (19.3%) and pain (4.8%). Significant antibody response rate was highest for serotype 14, followed by 23F, 19F, and 6B in all of the four time points examined. At week 48, patients who received two doses of 7-valent PCV had a significantly higher response rate to serotype 6B (P=0.03) and 23F (P=0.01) than those who received one dose; moreover, the former group also had a higher response rate to at least one (P=0.03) and two serotypes (P=0.02) in intention-to-treat analysis than the latter group. CONCLUSIONS HIV-infected adult patients on cART who received two doses of 7-valent PCV achieved better serological responses to at least one serotype than those who received one dose during the 48 weeks of follow-up.

Impact of vaccination with seven-valent pneumococcal conjugate vaccine on virologic and immunologic outcomes among HIV-infected adult patients in the era of highly active antiretroviral therapy. J Formos Med Assoc 2012; 111:445-51. [PMID: 22939663 DOI: 10.1016/j.jfma.2011.06.027] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2011] [Revised: 06/13/2011] [Accepted: 06/20/2011] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND/PURPOSE Pneumococcal polysaccharide vaccination may be associated with adverse outcomes in HIV-infected individuals who did not receive highly active antiretroviral therapy (HAART). Our aim was to evaluate the impact of vaccination with seven-valent pneumococcal conjugate vaccine (PCV) on the short-term clinical, virologic, and immunologic outcomes among HIV-infected adult patients in the HAART era. METHODS A total of 429 HIV-infected adult patients were enrolled from October 2008 to March 2010: 213 received two doses of seven-valent PCV given at a 4-week interval and 216 received one dose. All patients were given 1-week diary to record any discomfort after vaccination. Data of serial CD4 and plasma HIV RNA load measurements were recorded. RESULTS Of the 429 patients with a mean CD4 count of 305 cells/μL, 289 (67.4%) were receiving HAART and 175 (40.8%) had plasma HIV RNA load <40 copies/mL at vaccination. Of the 396 patients (92.3%) who returned the diary, injection site soreness (24.0%) and pain (10.4%) were the most commonly reported adverse effects. After 3-4 months of vaccination, CD4 count increased by 40 cells/μL in 278 patients (68.2%) who continued HAART, compared with a decrease of 38 cells/μL in 131 patients (31.8%) who were not on HAART (p < 0.001), while the respective change in plasma HIV RNA load was 0.8 versus 0.2 log(10) copies/mL (p = 0.09). One patient died, two developed opportunistic infections, and one developed pneumococcal pneumonia following vaccination. CONCLUSION Vaccination with seven-valent PCV among HIV-infected patients is generally safe, which has no detrimental effect on CD4 count and plasma HIV RNA load in patients receiving HAART.

Abstract
Individuals infected with HIV are at higher risk for severe cases of seasonal influenza infection and should receive annual doses of vaccine. Our objectives were to evaluate the immunogenicity of an influenza vaccine in 37 HIV-infected patients (HIV group) compared to 29 uninfected individuals (control group) and to carry out a clinical and virological surveillance of influenza during a 6-month follow-up. Both groups received the vaccine recommended for the southern hemisphere in 2008. Antibody responses to antigens H1N1, H3N2, and B were measured in blood samples at vaccination (T0) and after 1 month (T1). Influenza surveillance was performed by weekly telephone calls for a follow-up period of 6 months. Nasal washes were taken from subjects with respiratory symptoms. The direct immunofluorescence assay in house polymerase chain reaction (PCR) and real-time PCR were used for the detection of different respiratory viruses. The median age of the participants was 13.3 years (sd = 2.2) and 12.1 years (sd = 1.3) for the HIV group and control group, respectively. One month after vaccination (T1), both groups showed significant increases in the antibody geometric mean titers (GMTs) for all antigens. However, healthy controls showed higher values for antigens A/H1N1 and A/H3N2 (p = 0.002 and 0.001, respectively). There was a higher increase in the percentage of HIV-uninfected subjects with protective A/H1N1 antibodies (96.6%) compared to HIV-infected vaccinees (67.6%) at T1 (p = 0.004). Rhinovirus (27.7%) and coronavirus (22.5%) were the most prevalent agents identified in HIV-infected individuals. In the control group, the viruses most frequently found were rhinovirus (24.2%) and adenovirus (21.2%). The seroprotection rate for the H1N1 antigen was higher in the control group, which also showed a greater increase in GMTs for H1N1 and H3N2 antigens after immunization. Viral agents were identified in 39/60 (65%) episodes of respiratory infections from the HIV-infected group and in 17/32 episodes (53.1%) from the control group (p = 0.273).

Abstract
BACKGROUND The risk of pneumococcal disease persists, and antibody responses to revaccination with the 23-valent polysaccharide vaccine (PPV) are low among human immunodeficiency virus (HIV)-infected adults. We determined whether revaccination with the 7-valent pneumococcal conjugate vaccine (PCV) would enhance these responses. METHODS In a randomized clinical trial, we compared the immunogenicity of revaccination with PCV ( n = 131) or PPV (n = 73) among HIV-infected adults (median CD4 cell count, 533 cells/mm(3)) who had been vaccinated with PPV 3-8 years earlier. HIV-uninfected adults (n = 25) without prior pneumococcal vaccination received 1 dose of PCV. A positive response was defined as a >or=2-fold increase (from baseline to day 60) in capsule-specific immunoglobulin G, with a postvaccination level >or=1000 ng/mL for at least 2 of the 4 serotypes. RESULTS HIV-infected persons demonstrated a higher frequency of positive antibody responses to PCV than to PPV (57% vs 36%) (P = .004) and greater mean changes in the immunoglobulin G concentration from baseline to day 60 for serotypes 4, 9V, and 19F (P < .05, for all), but not for serotype 14. However, by day 180, both outcomes were similar. Responses to PCV were greater in frequency and magnitude for all serotypes in HIV-uninfected adults, compared with those in HIV-infected adults. CONCLUSIONS Among persons with HIV infection, revaccination with PCV was only transiently more immunogenic than PPV, and responses were inferior to those in HIV-uninfected subjects with primary vaccination. Pneumococcal vaccines with more robust and sustained immunogenicity are needed for HIV-infected adults. Clinical trial registration. ClinicalTrials.gov identifier NCT00622843.

Abstract
OBJECTIVES The acquisition of adequate vaccine-induced humoral immunity is especially important in HIV-infected individuals, who are at increased risk of infections. The aim of the study was to assess the safety of administering a complete vaccination programme to successfully treated HIV-infected adults and to evaluate specific humoral responses and the effect of highly active antiretroviral therapy (HAART) interruption on these responses. METHODS A placebo-controlled, double-blind clinical trial was designed and 26 HIV-infected adults enrolled. Study participants were randomized to receive either a complete immunization schedule with commercial vaccines or placebo for 12 months. HAART was then discontinued for 6 months. Specific humoral responses were evaluated at baseline, at month 12 and after HAART interruption and compared between groups. RESULTS There were neither local nor systemic secondary effects related to vaccination. Specific humoral responses to vaccines were adequate, but a loss of immunoglobulin G titres was observed after HAART interruption in 12 study participants. CONCLUSIONS HAART interruption may cause impairment of previously acquired vaccine-induced immunity in HIV-infected adults.

Abstract
BACKGROUND Long-term antibody responses to 23-valent pneumococcal polysaccharide vaccine (PPV) among HIV-infected patients receiving highly active antiretroviral therapy (HAART) are rarely investigated. METHODS Antibody responses to three pneumococcal capsular polysaccharides [Pneumococcal polysaccharide (PPS) 14, 19F and 23F] were assessed among 169 HIV-infected patients who received HAART and 23-valent PPV. Patients were stratified into four groups according to CD4 count at vaccination: group 1, CD4<100 cells/microL (n=35); group 2, CD4 100-199 cells/microL (n=36); group 3, CD4 200-349 cells/microL (n=34); and group 4, CD4>or=350 cells/microL (n=64). The proportion of patients who achieved increases in antibody titres of twofold or greater from baseline values (responders) was compared among the four groups of patients for five consecutive years after vaccination. RESULTS The proportion of responders to the three serotypes was significantly lower among patients in group 1 compared with those in the other three groups during yearly follow-up. Much faster loss of antibody responses was observed in group 1, although the rate of decline varied with the serotypes studied in the four groups. Compared with the nonresponders, more responders had CD4 counts >100 cells/microL at vaccination and achieved better virological suppression throughout the 5-year period, while the absolute increases of CD4 cell counts after HAART were not statistically significantly different. CONCLUSIONS Despite continued increases in CD4 cell counts after HAART, the proportion of HIV-infected patients who maintained antibody responses to PPV declined significantly over the 5-year follow-up period, especially among those who had CD4 counts <100 cells/microL at vaccination and who failed to achieve virological suppression.

Abstract
Whether gestational immunization of HIV-infected mothers with the 23-valent pneumococcal polysaccharide vaccine (PPV) confers maternal and infant early life, passive protection is not known. We evaluated safety, immunogenicity and placental transfer of antibodies in 44 HIV-infected women. Pneumococcal IgG antibodies against serotypes 1, 3, 5, 6B, 9V, and 14 were measured in mothers (pre-vaccination and at delivery), and infants (at birth, 1, 2, 3, and 6 months). PPV was safe and immunogenic in mothers. Newborns received 46-72% of maternal antibody titers. Overall, infants had antibody levels lower than protective by 2 months of age. Alternative pneumococcal vaccination of HIV-infected pregnant women should be explored with the aim of prolonging passive protection in their infants.

Abstract
OBJECTIVES Pneumococcal disease is an important cause of vaccine-preventable mortality. It is important to understand the burden and distribution of mortality so that prevention efforts can be targeted appropriately. This study evaluated pneumococcal disease mortality and its demographic correlates in California from 1989 to 1998. METHODS Deaths due to pneumococcal disease were identified from statewide vital records data using multiple cause-coded information. Denominator data were obtained from estimates from the California Department of Finance. Crude and age-adjusted mortality rates and 95% confidence intervals were calculated for each age, gender, and racial/ethnic group. RESULTS The age-adjusted pneumococcal disease mortality rate was 2.05 deaths per 100,000 population. Mortality was highest in elderly individuals (reaching 38.29 deaths per 100,000 population in individuals older than age 85). Age-adjusted mortality rates were elevated in the African American race/ethnicity group (2.96 deaths per 100,000 population) and males (2.67 deaths per 100,000 population). The majority of individuals who died of pneumococcal disease (78.9%) fell into at-risk groups indicated for vaccination. The majority of all pneumococcal deaths were caused by pneumococcal pneumonia. Mortality was seasonal, reaching a peak in the winter months. A decreasing trend in mortality was observed over the 10-year period examined. CONCLUSIONS Pneumococcal disease remains a significant cause of vaccine-preventable mortality in the California population. Greater efforts must be made to vaccinate at-risk individuals, especially those in demographic groups at highest risk of death.

Abstract
The clinical effectiveness of 23-valent pneumococcal vaccine in human immunodeficiency virus (HIV)-infected patients is controversial, because of the low immunological response in these subjects. We studied the clinical response of pneumococcal vaccine and the relative impact of influenza vaccine by administering both pneumococcal and influenza vaccine in a group of 150 HIV patients belonging to all CDC categories. In the group of 90 HIV-infected patients vaccinated against both pneumonia and influenza virus, there was a low incidence of mild influenza (13.3%) and no case of pneumococcal pneumonia. On the contrary, among 60 nonvaccinated HIV patients, 61.6% underwent mild to severe influenza and two developed pneumococcal pneumonia. 23-valent pneumococcal vaccine (PV) seems to be clinically effective in preventing pneumonia in HIV-infected patients, and even more if strengthened by influenza vaccine.

Abstract
We examined the peer-reviewed literature on the burden of bacterial pneumonia and the effectiveness of interventions for its prevention among HIV-infected adults in developed and developing countries. Bacterial pneumonia rates were up to 25-fold higher among HIV-infected adults than in the general community, with rates increasing as CD4+ T-cell count decreases. In developed countries, cohort studies showed that highly active antiretroviral therapy (HAART) had the most consistent effect on reducing pneumonia. In a prospective cohort and case-control studies from these regions, pneumococcal polysaccharide vaccine reduced pneumococcal disease in certain subgroups, particularly those with higher CD4+ T cells/microL. In patients with fewer than 200 CD4+ T cells/microL, antimicrobial prophylaxis was usually effective in reducing pneumonia. In sub-Saharan Africa, randomised controlled trials concluded that co-trimoxazole prophylaxis decreased rates of bacterial pneumonia, but pneumococcal polysaccharide vaccine prevented neither pneumonia nor invasive pneumococcal disease. Although not yet fully evaluated in Africa, based on experience in industrialised nations, use of HAART in Africa may have substantial potential to prevent bacterial pneumonia.
