BREAKING—Good & bad news—The Moderna #COVID19 vaccine fully protected against the UK 🇬🇧 #B117 variant... but was 6x less efficient at neutralizing the South African #B1351 variant in lab test. Moderna is testing a newly synthesized booster for it—3rd shot. washingtonpost.com/health/2021/01… Image
2) To be clear—6x less efficient doesn’t mean no protection against #B11351, it’s still good but not as good as before. As a precaution, Moderna announced it will launch two new studies—including adding a third shot of its current vaccine to boost its two-dose regimen.
3) press release is very cautiously worded—“6-fold reduction in neutralizing titers was observed with B.1.351 variant relative to prior variants. Despite this reduction, neutralizing titer levels w/ B.1.351 remain above levels expected to be protective.”
