Newly released data from the US Centers for Disease Control and Prevention (CDC) show that patients vaccinated with the new wave of bivalent COVID-19 boosters had better protection than those that have only taken the original versions. Moreover, results from the real-world data (RWD) study show that the bivalent boosters appear to work better the longer its been since the previous administration.
According to Andrew Joseph, “For people 65 and older, the relative vaccine effectiveness of the bivalent shot was 28% for people who had more recently had a dose of the original vaccine, and 43% for people who were at least eight months out. For people 50 to 64, the estimates of effectiveness were 31% and 48%, respectively, and for people 18 to 49, they were 30% and 56%.”
