Most Covid Vaccines Will Work as Boosters, Study Suggests

People looking for a booster shot of a Covid-19 vaccine probably don’t need to fret about what brand it is: Many combinations of shots are likely to provide strong protection, according to a large new study. In a comparison of seven different vaccine brands, British researchers found that most of them prompted a strong immune response, with the mRNA shots from Moderna and Pfizer-BioNTech eliciting the largest responses. The study was published on Thursday in The Lancet. These are welcome data for policymakers,” said Merryn Voysey, a statistician at the University of Oxford who was not involved in the study. “The most significant take-home message here is that there are a large number of excellent boosting options for third doses.”
