      Interpretive Summary for March 18, 2022

      Boosted is Best

      COVID-19 cases, hospitalizations, and deaths all continue to decrease in the United States. According to CDC’s COVID Data Tracker, as of March 16, 2022, 76.7% of the total U.S. population has received at least one dose of a COVID-19 vaccine, and 65.3% has completed their primary series. However, only about half of the booster-eligible population has received a booster dose and is considered up to date on their COVID-19 vaccines.

      Two new studies show the effectiveness of COVID-19 vaccines and boosters across periods of three variants of concern (Alpha, Delta, and Omicron). CDC released a study today showing that, among adults hospitalized with COVID-19 during the Delta and Omicron waves, those who received two or three doses of the Pfizer-BioNTech or Moderna vaccine had 90–95% less risk of dying or needing a ventilator compared with adults who were not vaccinated. Protection was highest in adults who received a third COVID-19 vaccine dose. A study published in the British Medical Journalexternal icon found that vaccines gave a high level of protection against hospitalization for all variants, but not as much for Omicron among adults who received only a primary series. However, boosters increased protection against Omicron. The study also showed that hospital patients who were vaccinated had much lower disease severity than patients who were not vaccinated.

      These studies emphasize the importance of staying up to date with vaccinations—they are our best protection against severe COVID-19 illness. Vaccination is also the safest way to reduce the chance that new variants will emerge. Find a vaccine provider and get your booster dose as soon as you can.
