Real-World Data Shows Bivalent Omicron COVID-19 Booster Reduces Hospitalization in Older Adults

January 11, 2023

Newly published research in Lancet finds that the bivalent Omicron COVID-19 booster shots substantially reduced hospitalization rates in people over the ages of 65. The study, which used real-world data of 85,000 older adults taking the Pfizer bivalent booster, showed that older adults taking it were 81% less likely to get hospitalized. The study showed it also decreased death rates.

According to Melissa Healy, “During a 70-day period between late September and mid-December, 297 people in the larger, unboosted group were hospitalized and 73 died. During the same period, six people in the boosted group were hospitalized and one died. When the Israeli researchers crunched the numbers, they determined that the boosters reduced a recipient’s risk of hospitalization to about one-fifth that of an unboosted person.”
