La evolución viral es un partido largo. Esto es lo que los científicos anticipan que ocurrirá. El 9 de enero de 2020, aproximadamente una semana después de que el mundo supo por primera vez que había una misteriosa serie de casos de neumonía en la región central de China, las […]
Background Vaccine effectiveness studies have not differentiated the effect of the delta (B.1.617.2) variant and potential waning immunity in observed reductions in effectiveness against SARS-CoV-2 infections. We aimed to evaluate overall and variant-specific effectiveness of BNT162b2 (tozinameran, Pfizer–BioNTech) against SARS-CoV-2 infections and COVID-19-related hospital admissions by time since vaccination among […]
A US Food and Drug Administration (FDA) advisory committee on Friday voted 19-0 to authorize second doses of the Johnson & Johnson COVID-19 vaccine in an effort to boost immunity. It was the second vote in as many days to back a change to a COVID vaccine timeline. In its […]

A panel of experts that advises the FDA on vaccine decisions voted unanimously Thursday to approve booster doses of Moderna’s COVID-19 vaccine. The 19 members of the FDA’s Vaccines and Related Biological Products Advisory Committee voted to authorize a 50-milligram dose — half the dose used in the primary series […]
A new US government study shows it isn’t risky and may even be a good idea to mix, rather than match, COVID-19 vaccines when getting a booster dose. The study also shows mixing different kinds of vaccines appears to spur the body to make higher levels of virus-blocking antibodies than […]
Background: While Coronavirus disease 2019 (Covid-19) vaccines are highly effective, breakthrough infections are occurring. Booster vaccinations have recently received emergency use authorization (EUA) for certain populations but are restricted to homologous mRNA vaccines. We evaluated homologous and heterologous booster vaccination in persons who had received an EUA Covid-19 vaccine regimen. […]
COVID-19 cases are continuing to decrease across most of the country, but the overall level of community transmission in the United States is high. The current 7-day average of daily new cases is 84,555, a 12.5% decrease from the previous 7-day period. Getting vaccinated is the best way to help […]
Vaccines are an important part of stopping COVID-19. But just as an umbrella won’t keep you completely dry in a rainstorm, no vaccine is 100% effective. Getting vaccinated, wearing a mask in indoor public places, & avoiding crowds can help protect you and others. More: https://bit.ly/cdc-protectyourself. Créditos: Comité científico Covid
Emerging SARS-CoV-2 variants pose a challenge to the effectiveness of current vaccines. A vaccine capable of controlling current SARS-CoV-2 variants of concern, as well as preventing infection by other sarbecoviruses, would be optimal. New research findings are summarized in a short video. https://www.facebook.com/watch/?v=286774673059879&extid=WA-UNK-UNK-UNK-AN_GK0T-GK1C&ref=sharing Créditos: Comité científico Covid
