The first approach would use variant-specific booster shots, such as mRNA-1273351, but at a lower dosage than the original vaccine. The second one would combine the initial vaccine with a variant-specific vaccine into a single shot at 50 micrograms or lower, Moderna stated. The 3rd would evaluate a third shot of the initial vaccine at a lower dose.
Moderna said it also plans to evaluate the initial vaccine and the new booster shot as a two-dose routine in people without coronavirus antibodies.
