The concurrent administration of bivalent mRNA COVID-19 boosters and influenza vaccines should be considered as a strategy to potentiate neutralizing antibody responses against SARS-CoV-2. Concurrent administration of the bivalent COVID-19 booster and the inactivated influenza vaccine may result in higher and ...
5 days ago · Background: This study (ARVAC-F2-3-002) assessed the immunogenicity, safety, and tolerability of a recombinant booster vaccine (ARVAC) containing the receptor binding domain of the SARS-CoV-2 Spike protein in three different versions: Gamma (ARVACGamma), Omicron BA.4/5 (ARVACOmicron), and Gamma/Omicron Bivalent (ARVACBivalent). Methods: Randomized, double-blind, crossover, placebo-controlled ...
4 days ago · In January, a different self-amplifying mRNA vaccine (ARCT-154) made by Arcturus Therapeutics and CSL received full approval as a COVID-19 booster in Japan. In the pivotal Phase 3 study, the vaccine was administered at a 5 microgram dose, which resulted in higher immune responses than a 30 microgram dose of Comirnaty, the Pfizer/BioNTech vaccine.
4 days ago · Understanding the association between booster vaccination and COVID-19 outcomes can help strengthen post-pandemic messaging and strategies to increase vaccination and reduce severe and long-term consequences of COVID-19. Using the Household Pulse Survey data collected from U.S. adults from 9 December 2022 to 13 February 2023 (n = 214,768), this study assessed the relationship between COVID-19 ...
