Of greatest concern — the vaccine was 96% efficacious against the original strain, nearly 86% efficacious against the new UK strain, and, in a smaller South African study, 60% efficacious against the new S African strain (among specifically HIV-negative South Africans, it did worse among HIV positive and negative S Africans).
Novavax was the most promising vaccine early on, and its (preliminary) efficacy of 96% against the original strain is the highest yet. So, I worry the other vaccines could be less than 60% efficacious against the S African strain.
I am very glad Moderna and Pfizer have begun work on a modified shot for the new mutations.
