<div>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.</div>
