Vaccines vs variants - M_T - 07-21-2021 A (not-yet-reviewed) study has been posted that looks at neutralizing titers for those with different vaccines against the variants of concern (VOC) (including Delta and Lambda). Quote:SARS-CoV-2 variants have been classified by the World Health Organization (WHO)  based on increased transmissibility and/or pathogenicity as variants of concern (VOC;  Alpha (B.1.1.7), Beta (B.1.351), Gamma (B.1.1.248) and Delta (B.1.617.2) and variants of interest (VOI; Epsilon (B.1.427/B.1.429), Iota (B.1.526), and Delta plus (AY.1) and Lambda (C.37) Quote:This study compared the neutralization titers of serum antibodies from individuals immunized with three U.S. FDA Emergency use authorization vaccines (BNT162b2 ["Pfizer"], mRNA-1273 ["Moderna"] and Ad26.COV2.S ["J&J"]) against viruses with the VOC and Lambda spike proteins. If you download it, you may find it useful to skip to the Discussion section: Quote:In sera collected As I read that (I am neither a physician or one trained in this area), the Pfizer & Moderna vaccine series should provide much better than 50% protection against getting infected with the variants tested.  The J&J vaccine will provide less than 50% protection against getting infected, but will provide sufficient protection against getting severe disease. To be responsible, I also point out that these results differ from some other studies for J&J. Quote:The data reported here differ somewhat from those reported by Barouch et al. and Finally, the authors reference studies that suggest a booster for J&J increase the neutralizing titers (thus providing better resistance to infection). RE: Vaccines vs variants - Hurlburt88 - 07-26-2021 THanks for posting. I"ll stay tuned for J&J booster when approved & recommended. |
