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. METHODS To evaluate […]
“Test and treat” is a critical strategy for people and society returning to more normal activities. Now that the early responses to the COVID-19 pandemic have — sort of — been met (ie, minimizing infection, spread, illness, and death with masks, testing, contact tracing, social distancing, and vaccines), we are […]

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 […]
The human body needs a lot of oxygen: about a cup a minute, just to stay alive. If we can’t get the amount we need because of injury or disease, like COVID-19, our bodies quickly start to suffer from oxygen deprivation. After just a few minutes, abnormally low oxygen levels […]
A new omicron subvariant of the virus that causes COVID-19, BA.2, is quickly becoming the predominant source of infections amid rising cases around the world. Immunologists Prakash Nagarkatti and Mitzi Nagarkatti of the University of South Carolina explain what makes it different from previous variants, whether there will be another […]
