A United Kingdom Health Security Agency report published on Thursday suggests that the effectiveness of the COVID-19 booster against symptomatic infections of the omicron variant wanes within 10 weeks.

In all cases, data showed that the vaccines’ effectiveness against omicron was lower compared with their effectiveness against delta. The effectiveness of both the Moderna and Pfizer boosters was also found to decrease within weeks of people receiving the extra dose.
