The Australian Department of Health and Aged Care said it does not promote one vaccine over another. Modernas team recently showed that a half dose of the vaccine still sent antibody levels soaring. The most significant finding suggested that people who initially got the J&J vaccine seem to have gotten the best response if they got Pfizer or Moderna as their booster. Study compares effectiveness of Pfizer vs. Moderna booster COVID vaccines after third dose. There is limited evidence showing the effect of that dose, and none on how long the higher antibody levels might last. An ideal comparative effectiveness study of mRNA vaccines should cover racially diverse populations and evaluate possible differences in vaccine efficacy based on the time when an individual completed the primary vaccination series.

AmeshA.Adalja, MD, infectious disease expert and asenior scholarat the Johns Hopkins Center for Health Security, emphasizes that both vaccines are crucial tools for curbing the pandemic. However, its important to note that the dose of the Moderna booster given in the study was twice as high as what will be given in the real world. The mistake was approving this as a one-dose vaccine to start with because it was such an outlier, says John Moore, a professor of microbiology and immunology at Weill Cornell Medicine. It was a constant refrain from federal health officials after the coronavirus vaccines were authorized: These shots are all equally effective. Its difficult to make head-to-head comparisons because the Moderna vaccine is a higher dose than Pfizer and the doses are spaced further apart, which may explain higher efficacy seen.. News-Medical.

A second CDC report looked at 25 U.S. states between April and December and similarly found that while defence against infection waned, those with boosters had much higher protection against symptoms both when Delta was dominant and when Omicron overtook it. The study, which was sponsored by the National Institutes of Health, involved 458 volunteers. "Moderna does seem to have a more durable protection, which is going to protect you for potentially a bit longer against those breakthrough infections," Grindrod said. Both vaccines reduced the absolute risks of breakthrough SARS-CoV-2 infections and severe COVID-19 outcomes. People who got the Moderna vaccine for their original shots and Moderna again for their booster appear to have gotten the best immune response, followed by those who got Pfizer boosted by Moderna and then Moderna boosted by Pfizer although the increase in immune response with the mRNA vaccines was probably too small to really make a difference in protection in most groups. "No new or unexpected safety signals have been reported," it said. Three million doses of Moderna's BA.4/5 vaccine are expected to be available from April. Scientists measure antibodies not only because theyre an important part of the immune defense, but also because its very easy to do so. Mathur, Neha.
