High vaccination success rate
Nevertheless, Arbel and his team analyzed the effects of the bivalent booster with the vaccine against the original SARS-CoV-2 variant (“wild type”) and against the omicron mutations BA.4/5 in the first three months of using the adapted vaccine . The scientists compared those 134,215 insured persons who had received a bivalent vaccine at an average age of 76.9 years (for 89 percent it was already the fifth vaccination; note), with 435,304 elderly persons with an average age of 74.7 years who had not had been vaccinated again. However, half of this group had already had three vaccinations, and 40 percent had received four vaccinations. Almost a third of all people whose data was analyzed in the study had had Covid-19 disease, which also leads to immunity.
