Rss Feed - 4 hours 6 min ago
The technical name of the vaccine is ChAdOx1 nCoV-19 (AZD1222), as it is made from a virus called ChAdOx1, which is a weakened and non-replicating version of a common cold virus (adenovirus). The vaccine has been engineered to express the SARS-CoV-2 spike protein.

Research suggests protective effect of influenza vaccine against COVID-19 severity and mortality

Rss Feed - 5 hours 3 min ago
A new study involving over 92,000 patients with COVID-19 in Brazil shows that the odds of severe disease, ventilatory support requirement, and death are reduced with a recent trivalent flu vaccine. This seems to indicate that these vaccines should be used as widely as possible to reduce the risk of severe COVID-19, especially among high-risk groups. The study is published on the preprint server medRxiv* in June 2020.
