Adverse events following quadrivalent meningococcal CRM-conjugate vaccine (Menveo®) reported to the Vaccine Adverse Event Reporting system (VAERS), 2010-2015.
Limited data are available describing the post-licensure safety of meningococcal vaccines, including Menveo®. We reviewed reports of adverse events (AEs) to the Vaccine Adverse Event Reporting System (VAERS) to assess safety in all age groups. ⋯ In our review of VAERS reports, findings of AEs were consistent with the data from pre-licensure studies. Vaccine providers should continue to emphasize and adhere to proper administration of the vaccine.

The Middle East respiratory syndrome coronavirus (MERS-CoV) was first discovered in late 2012 and has gone on to cause over 1800 infections and 650 deaths. There are currently no approved therapeutics or vaccinations for MERS-CoV. ⋯ In this study, we demonstrate protection induced by vaccination with a recombinant MERS-CoV S nanoparticle vaccine and Matrix-M1 adjuvant combination in mice. The MERS-CoV S nanoparticle vaccine produced high titer anti-S neutralizing antibody and protected mice from MERS-CoV infection in vivo.

Bivalent rLP2086 (Trumenba®; MenB-FHbp), composed of two factor H binding proteins (FHbps), is a vaccine approved in the United States for prevention of Neisseria meningitidis serogroup B (MnB) invasive meningococcal disease (IMD). Bactericidal activity of sera from subjects vaccinated with bivalent rLP2086 was assessed against MnB isolates from recent disease outbreaks in France. ⋯ Each of the representative French outbreak isolates was killed by sera from subjects vaccinated with bivalent rLP2086. Vaccination elicited an immune response with bactericidal activity against these diverse isolates in a large proportion of subjects at risk. These results provide additional support for the licensure strategy of testing MnB strains expressing vaccine-heterologous FHbp variants in hSBAs and further illustrate the breadth of efficacy of this protein-based MnB vaccine.

Randomized Controlled Trial Multicenter Study
Immunogenicity and safety of an AS03-adjuvanted H7N1 vaccine in healthy adults: A phase I/II, observer-blind, randomized, controlled trial.
H7 influenza strains have pandemic potential. AS03-adjuvanted H7N1 A/mallard/Netherlands/12/2000 split-virion vaccine formulations were evaluated as model H7-subtype vaccine and tested after H7N9 emerged in China, and caused severe human disease with high mortality. ⋯ Adjuvanted H7N1 vaccine formulations had an acceptable safety profile and induced an antibody response after 2 doses with cross-reactivity to H7N9. ClinicalTrials.gov: NCT01934127.

Randomized Controlled Trial Clinical Trial
Exploratory efficacy endpoints in the Community-Acquired Pneumonia Immunization Trial in Adults (CAPiTA).
The Community-Acquired Pneumonia Immunization Trial in Adults (CAPiTA) assessed vaccine-type community-acquired pneumonia (VT-CAP) and vaccine-type invasive pneumococcal disease (VT-IPD) prevention with 13-valent pneumococcal conjugate vaccine (PCV13) in adults aged ⩾65years. We report vaccine efficacy (VE) of PCV13 for the remaining 23 exploratory endpoints and serotype distributions for pneumococcal CAP and IPD. ⋯ The results of this analysis yielded statistically significant PCV13 VE for all episodes of confirmed pneumococcal CAP (including NB/NI and culture-confirmed episodes) and for all episodes of IPD in adults aged ⩾65years. These findings are consistent with the primary efficacy analysis. ClinicalTrials.gov identifier: NCT00744263.
