The first participants in Moderna’s trial assessing new variant-specific booster shots have been vaccinated, the company announced.
Secondly, Moderna said it plans to study a combination of the original vaccine and the variant-specific one in a single jab at 50 micrograms. Lastly, it will study the effects of the variant booster shot at a higher dose, 50 micrograms. In a recent published study, the biotech giant said its existing COVID-19 jab was found to have a six-fold reduction in vaccine-induced antibodies against the B.1.351 variant. Despite this reduction, however, "neutralizing titer levels with B.1.351 remain above levels that are expected to be protective," the company said.More Related News
