From the end of March until the end of May 2022, 39% of those who were hospitalized with COVID-19 completed their primary vaccination series and received one booster, according to a CDC study.
However, the study also found that hospitalization rates among unvaccinated adults were 3.4 times higher compared to those who were vaccinated.

Results indicated that during the three-month period, a time when the BA.2 Omicron subvariant was dominant, hospitalization rates rose among all age groups, but were particularly higher among adults 65 and older.
Those with two booster shots were less likely to be hospitalized than those with just one during the BA.2 period.
Overall, results showed that vaccinations were more effective at preventing hospitalization when the Delta variant was dominant compared to later variants.
COVID vaccine makers: Moderna (NASDAQ:MRNA), Pfizer (NYSE:PFE), BioNTech (NASDAQ:BNTX), and Novavax (NASDAQ:NVAX).
Updated booster shots that are effective against the BA.4 and BA.5 Omicron subvariants are expected to be available shortly after Labor Day.
