TL;DR: A two-dose regimen of BNT162b2 conferred 95% protection against Covid-19 in persons 16 years of age or older and safety over a median of 2 months was similar to that of other viral vaccines.
Journal ArticleDOI
Invasive pneumococcal disease caused by nonvaccine serotypes among alaska native children with high levels of 7-valent pneumococcal conjugate vaccine coverage.

TL;DR: Alaska Native children are experiencing replacement invasive pneumococcal disease with serotypes not covered by heptavalent pneumitiscal conjugate vaccine, which emphasizes the importance of ongoing surveillance and development of expanded valency vaccines.
Journal ArticleDOI

TL;DR: Estimating causes of pneumonia in young African and Asian children, using novel analytical methods applied to clinical and microbiological findings, estimated that viruses accounted for 61·4% (95% credible interval [CrI] 57·3–65·6) of causes, whereas bacteria accounted for 27·3% (23·3-31·6).
Journal ArticleDOI
Indirect effect of conjugate vaccine on adult carriage of Streptococcus pneumoniae: an explanation of trends in invasive pneumococcal disease.
Laura L. Hammitt,Dana Bruden,Jay C. Butler,Henry C. Baggett,Debby Hurlburt,Alisa Reasonover,Thomas W. Hennessy +6 more
TL;DR: Pediatric vaccination with PCV7 has resulted in decreasedPCV7-type pneumococcal carriage among adults and helps to explain recent decreases in the rate of PCV 7-type invasive pneumococCal disease among adults.
Journal ArticleDOI
Population effect of 10-valent pneumococcal conjugate vaccine on nasopharyngeal carriage of Streptococcus pneumoniae and non-typeable Haemophilus influenzae in Kilifi, Kenya: findings from cross-sectional carriage studies

TL;DR: After programmatic use of PCV10 in Kilifi, carriage of vaccine serotypes was reduced by two-thirds both in children younger than 5 years and in older individuals, suggesting that PCV 10 introduction in Africa will have substantial indirect effects on invasive pneumococcal disease.
