Today, CDC published <a href="https://www.cdc.gov/mmwr/volumes/70/wr/mm7044e1.htm?s_cid=mm7044e1_w">new science</a> reinforcing that vaccination is the best protection against COVID-19. In a new <em>MMWR</em> examining more than 7,000 people across 9 states who were hospitalized with COVID-like illness, CDC found that those who were unvaccinated and had a recent infection were 5 times more likely to have COVID-19 than those who were recently fully vaccinated and did not have a prior infection.
