  • In addition, a 2nd booster resulted in an increase in neutralizing antibodies against VOCs Alpha, Beta, Delta, and Omicron subvariants BA.1 and BA.2. (researchsquare.com)
  • Neutralization of Omicron BA.1 and BA.2 was limited even after the 2nd booster vaccination indicating that an antibody-mediated protection against infection with this VOC is unlikely, as evidenced by the fact that three of the quadruple vaccinated individuals became infected with BA.1 during the course of the study. (researchsquare.com)
  • Interestingly, in subjects with Omicron BA.1 breakthrough infection, a significant increase in neutralizing antibodies to all tested VOCs studied was observed after the 2nd booster vaccination. (researchsquare.com)
  • Omicron is characterized by a multitude of mutations particularly in the Spike sequence and up to now at least three circulating sub-lineages (BA.1, BA.2 21 and BA.3 22 ) have been identified. (researchsquare.com)

  • Here we showed that it's possible to design a variant-specific booster that doesn't just strengthen the antibodies people already have but elicits new antibodies. (nih.gov)
  • In order to stimulate the development of novel and varied antibody-producing cells, the booster vaccine must target a variant that is very divergent from the primary SARS-CoV-2 strain. (selfgrowth.com)
  • In this study, we show that it is possible to build a booster vaccine against a specific variation that does more than just increase the effectiveness of preexisting antibodies. (selfgrowth.com)
  • Ellebedy noted that updating the vaccine so that it targets the new strain was the reasonable next step, but that due to the initial vaccines' efficacy against the original SARS-CoV-2 strain, producing a successful booster vaccine against the variant became difficult. (selfgrowth.com)
  • The second booster vaccination resulted in an increase in anti-RBD IgG antibodies and neutralizing antibodies against B.1 in all individuals tested, then remained nearly constant over the observed period. (researchsquare.com)

  • The study, published in Science , also showed that the increased neutralizing antibody responses were sustained for at least eight weeks after the boost, were significantly higher than after the primary vaccine series, and generated high-level protection - meaning the ability to significantly limit virus from replicating in the lungs and nose. (nih.gov)
