Abstract
BACKGROUND HIV subtypes B and C together account for around 60% of HIV-1 cases worldwide. We evaluated the safety and immunogenicity of a subtype B DNA vaccine prime followed by a subtype C viral vector boost. METHODS Fourteen healthy adults received DNA plasmid encoding HIV-1 subtype B nef/tat/vif and env (n = 11) or placebo (n = 3) intramuscularly (IM) via electroporation (EP) at 0, 1, and 3 months, followed by IM injection of recombinant vesicular stomatitis virus encoding subtype C Env or placebo at 6 and 9 months. Participants were assessed for safety, tolerability of EP, and Env-specific T-cell and antibody responses. RESULTS EP was generally well tolerated, although some device-related adverse events did occur, and vaccine reactogenicity was mild to moderate. The vaccine stimulated Env-specific CD4 + T-cell responses in greater than 80% of recipients, and CD8 + T-cell responses in 30%. Subtype C Env-specific IgG binding antibodies (bAb) were elicited in all vaccine recipients, and antibody-dependent cell-mediated cytotoxicity (ADCC) responses to vaccine-matched subtype C targets in 80%. Negligible V1/V2 and neutralizing antibody (nAb) responses were detected. CONCLUSIONS This prime/boost regimen was safe and tolerable, with some device-related events, and immunogenic. Although immunogenicity missed targets for an HIV vaccine, the DNA/rVSV platform may be useful for other applications. TRIAL REGISTRATION CLINICALTRIALS gov: NCT02654080.

Abstract
The HIV-1 envelope glycoprotein spike is the target of antibodies, and therefore represents the main viral antigen for antibody-based vaccine design. One of the challenges in HIV-1 vaccine development is finding efficient ways for the immune system to recognize and respond to HIV-1 without establishing an infection. Since HIV-1 enters the body at mucosal surfaces, induction of immune response at these sites is a preferred preventive approach. Nasal administration is a very effective route for mucosal immunization since it can stimulate mucosal immune responses both locally and distantly. In this paper, Luna develops a safe, short carbon nanotube (CNT)-based, needle-free delivery platform known as "CNTVac". The size of short CNT was controlled to possess HIV-1 particle-like morphology (100-200 nm) capable of efficiently delivering a broad range of antigens intranasally. PEG-Lipid served as the antigen conformation protector and mucosal barrier penetration enhancer (Schematic Figure) was localized between V1V2 antigens, which caused highly enhanced local IgA and systemic antibody IgG responses in mice and rabbits. The short CNT incorporated with PEG-Lipid could not only serve as efficient delivery system but also reduce the amount of lipid usage in order to balance the vaccine dosage in order to eliminate the potential adverse effect. These data suggest a promising platform technology for vaccine delivery.

Abstract
Decrypting the B cell ontogeny of HIV-1 broadly neutralizing antibodies (bNAbs) is paramount for vaccine design. Here, we characterized IgA and IgG bNAbs of three distinct B cell lineages in a viremic controller, two of which comprised only IgG+ or IgA+ blood memory B cells; the third combined both IgG and IgA clonal variants. 7-269 bNAb in the IgA-only lineage displayed the highest neutralizing capacity despite limited somatic mutation, and delayed viral rebound in humanized mice. bNAbs in all three lineages targeted the N332 glycan supersite. The 2.8-Å resolution cryo-EM structure of 7-269-BG505 SOSIP.664 complex showed a similar pose as 2G12, on an epitope mainly composed of sugar residues comprising the N332 and N295 glycans. Binding and cryo-EM structural analyses showed that antibodies from the two other lineages interact mostly with glycans N332 and N386. Hence, multiple B cell lineages of IgG and IgA bNAbs focused on a unique HIV-1 site of vulnerability can codevelop in HIV-1 viremic controllers.

Abstract
Objectives SARS‐CoV‐2 can be transmitted by aerosols, and the ocular surface may be an important route of transmission. Little is known about protective antibody responses to SARS‐CoV‐2 in tears after infection or vaccination. We analysed the SARS‐CoV‐2‐specific IgG and IgA responses in human tears after either COVID‐19 infection or vaccination. Methods We measured the antibody responses in 16 subjects with COVID‐19 infection for an average of 7 months before, and 15 subjects before and 2 weeks post‐Comirnaty (Pfizer‐BioNtech) vaccination. Plasma, saliva and basal tears were collected. Eleven pre‐pandemic individuals were included as healthy controls. Results IgG antibodies to spike and nucleoprotein were detected in tears, saliva and plasma from subjects with prior SARS‐CoV‐2 infection in comparison with uninfected controls. While receptor‐binding domain (RBD)‐specific antibodies were detected in plasma, minimal RBD‐specific antibodies were detected in tears and saliva. By contrast, high levels of IgG antibodies to spike and RBD, but not nucleoprotein, were induced in tears, saliva and plasma of subjects receiving 2 doses of the Comirnaty vaccine. Increased levels of IgA1 and IgA2 antibodies to SARS‐CoV‐2 antigens were detected in plasma following infection or vaccination but were unchanged in tears and saliva. Comirnaty vaccination induced high neutralising Abs in the plasma, but limited neutralising antibodies were detected in saliva or tears. Conclusion Both infection and vaccination induce SARS‐CoV‐2‐specific IgG antibodies in tears. RBD‐specific IgG antibodies in tears were induced by vaccination but were not present 7 months post‐infection. This suggests the neutralising antibodies may be low in the tears late following infection.

Abstract
The vagina is an excellent site for topical passive immunization, as access is relatively easy, and it is an enclosed space that has been shown to retain bioactive antibodies for several hours. A number of sexually transmitted infections could potentially be prevented by delivery of specific monoclonal antibodies to the vagina. Furthermore, our group is developing antisperm antibodies for vaginally delivered on-demand topical contraception. In this article, we describe physical features of the vagina that could play a role in antibody deployment, and antibody modifications that could affect mAb retention and function in the female reproductive tract. We also review results of recent Phase 1 clinical trials of vaginal passive immunization with antibodies against sexually transmitted pathogens, and describe our current studies on the use of anti-sperm mAbs for contraception.

Antibody Responses to SARS-CoV-2 mRNA Vaccines Are Detectable in Saliva. Pathog Immun 2021; 6:116-134.

Abstract
The approved Pfizer and Moderna mRNA vaccines are well known to induce serum antibody responses to the SARS-CoV-2 Spike (S)-protein. However, their abilities to elicit mucosal immune responses have not been reported. Saliva antibodies represent mucosal responses that may be relevant to how mRNA vaccines prevent oral and nasal SARS-CoV-2 transmission. Here, we describe the outcome of a cross-sectional study on a healthcare worker cohort (WELCOME-NYPH), in which we assessed whether IgM, IgG, and IgA antibodies to the S-protein and its receptor-binding domain (RBD) were present in serum and saliva samples. Anti-S-protein IgG was detected in 14/31 and 66/66 of saliva samples from uninfected participants after vaccine doses-1 and -2, respectively. IgA antibodies to the S-protein were present in 40/66 saliva samples after dose 2. Anti-S-protein IgG was present in every serum sample from recipients of 2 vaccine doses. Vaccine-induced antibodies against the RBD were also frequently present in saliva and sera. These findings may help our understanding of whether and how vaccines may impede SARS-CoV-2 transmission, including to oral cavity target cells.
