About The Study: When Omicron was the dominant variant during the early months of 2022 from January to April, COVID-19-associated hospitalization rates were 10.5 times higher in unvaccinated adults and 2.5 times higher in vaccinated adults with no booster dose compared with those who had received a booster dose. Results of the study suggest that clinicians and public health practitioners should continue to promote vaccination with all recommended doses for eligible persons.
