The FDA and the CDC approved COVID-19 booster shots for all adults Friday. Health officials are urging U.S. residents to get a booster, or to get their first vaccines if they haven’t already, in order to curb another winter surge as the holiday travel rush is expected to approach pre-pandemic levels. Cases have gone up nearly 30% over the last two weeks. Recorded U.S. COVID deaths in 2021 have now surpassed 2020 deaths, despite the wide availability of vaccines.
