Moderna’s third dose, following Astrazeneca’s two-dose vaccine, was able to induce a 29-33-fold increase in immunity against the “Omicron” virus, which was sufficient to counteract Omicron. Effectiveness against the second viral subspecies (BA.2), the current main strain. are 1.7 times less than the first subspecies, therefore it is necessary to follow up on further studies whether How long will the level of immunity for the 3rd vaccination last? which has preliminary information from some countries that Live for about 3-6 months.
