After long delays, the Food and Drug Administration is expected to decide within weeks whether to authorize Novavax’s vaccine. It’s late in the […]

Having had a recent acute febrile illness was associated with an increased risk for ischemic stroke, whereas having received an influenza vaccination was associated with a reduced risk for stroke in a large new case–control study. “While influenza vaccination is a cost-effective method to prevent influenza, it is also an […]
Two retrospective Israeli cohort studies suggest that, after a fourth dose of BNT162b2, participants aged ≥60 had reduced risk for infection and severe disease in the short term. In the wake of the surging SARS-CoV-2 Omicron variant, a fourth dose of the Pfizer-BioNTech (BNT162b2) vaccine in those aged ≥60 was […]
Abstract BACKGROUND With large waves of infection driven by the B.1.1.529 (omicron) variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), alongside evidence of waning immunity after the booster dose of coronavirus disease 2019 (Covid-19) vaccine, several countries have begun giving at-risk persons a fourth vaccine dose.

Measures to reduce transmission of SARS-CoV-2 have also been effective in reducing the transmission of other endemic respiratory viruses. As many countries decrease the use of such measures, we expect that SARS-CoV-2 will circulate with other respiratory viruses, increasing the probability of co-infections. The clinical outcome of respiratory viral co-infections […]
