The headline doesn't quite do the article justice. Boosters in this one study reduced measured infection (they didn't measure actual hospitalization/disease!) by some amount in the very short term. But experts say this tells us very little about what effect they will have over even months, instead of weeks/days. Last paragraph: > If the booster’s additional immunity fades quickly, or if the booster campaign distracts from surveillance efforts or from reaching people who have not been vaccinated at all, Dowdy says, the effort will have little long-term impact: “We need longer term data before we can say that giving people boosters at any given interval is the right strategy.”
