Serological responses and vaccine effectiveness for extended COVID-19 vaccine schedules in England

Nature Communications, 2021
The UK extended the interval until the second COVID-19 vaccine dose up to 12 weeks. Here, the authors show in a cohort of 750 participants aged 50–89 years that the extended schedule results in higher antibody titers and estimate a higher vaccine ...

Genetic Diversity of Meningococcal Serogroup B Vaccine Antigens among Carriage Isolates Collected from Students at Three Universities in the United States, 2015–2016

mBio, 2021
The impact of serogroup B meningococcal (MenB) vaccines on carriage is not completely understood. Using whole-genome sequencing data, we assessed the diversity and distribution of MenB vaccine antigens (particularly FHbp) among 1,514 meningococcal ...
