The increased incidence of breakthrough infections has led to a few countries administering booster shots. Now, a small study involving just 33 participants measured the antibody responses before and soon after a booster dose was administered. The study found “large antibody responses” soon after the booster dose was administered. The researchers found that a booster dose still has “high” capability to neutralise the Delta variant. In short, the efficacy to neutralise the Delta variant even after a booster shot did not become comparable with the strains that were in circulation early during the pandemic.
