In this review, we provided an up-to-date summary for current COVID-19 vaccines, discussed the biological basis and clinical impact of SARS-CoV-2 variants and subvariants, and analyzed the effectiveness of various vaccine booster regimens against different SARS-CoV-2 strains. Additionally, we ...
compared to adults [26]. Besides, a booster dose was reported to significantly increase neutralizing antibody titer [27] but AstraZeneca did not solicit regulatory authorization for a booster dose of its vaccine. In several countries such as the UK and Australia, mRNA vaccines (BNT162b2 and mRN...
In conclusion, our results indicate the short-term effectiveness of booster vaccination using either the mRNA or inactivated vaccine in preventing SARS-CoV-2 Omicron BA.2 infection. As such, surge booster campaigns could be strategically used to rapidly boost population immunity before upcoming waves ...
Also, no serious adverse events were reported in the AWcorna booster group. The researchers said this vaccine booster's effectiveness in preventing COVID-19 infection remains to be determined, but its potent antibody induction supports the emergency use as a heterologous booster in China. The ongoi...
