It’s important to keep up on the latest reports of effectiveness, but it’s also a daunting task, given the flood of information (and misinformation) coming at us from so many directions.
Currently, studies from around the world are showing the effectiveness of the vaccines and booster together in preventing serious symptoms, hospitalizations, and COVID-related death. February 1, 2022, the CDC released a report showing COVID hospitalization rates were 23 times higher for unvaccinated people. Plus, the data showed that if you were up to date with your vaccines (including having a booster) your chances of being hospitalized fell even more.
The FDA has also authorized — and the CDC has approved — booster shots for all three vaccines, along with a “mix-and-match” approach that allows people to choose a different vaccine for their booster than the one they started with.
