The newly authorized shots are specifically tailored to combat omicron subvariants and the first updates to the original COVID-19 vaccines since they were introduced in late 2020. — The Conversation
and other laboratory findings, such as the ability of antibodies to neutralize the virus, to decide whether to authorize the bivalent boosters.over whether it is appropriate for the FDA to approve a booster without direct human data to support it. However, the FDA has stated that millions of people have safely received the mRNA vaccines – which were originally tested in humans – and that the changes in the mRNA sequences in the vaccines.
It is also noteworthy that influenza vaccines are introduced each year based on prediction of the strain that is likely to be dominant,Based on available evidence from the previous COVID-19 vaccines, we believe it is very likely that the new boosters will continue to offer strong protection from4. Will it only be a booster shot?as a booster shot at least two months after the completion of the primary series – or initial required shots – or following a previous booster shot.
Because of the superiority of the bivalent vaccines, the FDA has also removed the use authorization for the original monovalent Moderna and Pfizer COVID-19 vaccines for booster purposes in individuals 18 years of age and older and 12 years of age and older, respectively., and as such are meant to be used only as boosters and not in people who have never received a COVID-19 vaccination.
If it is a minor mutation or set of mutations when compared to the original strain or to omicron variants BA.4 and BA.5, the new shots will provide good protection. However, if a hypothetical new strain were to possess highly unique mutations in its spike protein, then it’s likely that it could once again dodge immune protection.
On the flip side, the successful development of the updated vaccines demonstrates that the mRNA vaccine technology is nimble and innovative enough that – within a couple of months of the emergence of a new variant – it is now likely possible to develop and distribute new vaccines that are tailor-made to fight an emerging variant.
