    For those that don’t know, even if the annual vaccination doesn’t target the dominant specific strain that year, it still provides more protection than no vaccine!

    Where is my mRNA flu shot? I know research was on going, with all indications that they provided wider strain coverage, and could be updated faster as in this case right here.

    The mRNA-1010 in trials had better efficacy than a regular flu vaccine (40,000 person study, 11 countries).

    Makes me so angry. The US was really leading the way, and now is drastically set back. I am not being pro-us, I would be happy if any country was leading the way. But the US was getting there and then the “political morons” decided the US shouldn’t do that anymore.

    Gotta hope for UK, France, and Germany, they are the leaders now.

    Hopefully it doesn’t get too awful in the US. With RFK at the wheel, I doubt that the Fed is going to be doing a ton to help. Keep your elders inside!

    Got double boosted and already lying here with an annoying cold. I hope it doesn’t get much worse…

    As I understand it…the northern and southern hemisphere depend on each other in determining which strain to include in the vaccine. So the north looks at what has happened in the south to determine what to include in the north for the next season right? So I wonder…why do this? Why not just include all 14 of the known strains and be done with it? Is there an incompatibility that we don’t know about? Asking for a friend…

      Because we haven’t yet made a vaccine that is capable of targeting multiple strains effectively much less cost effectively. There are a few multivalent flu vaccines in clinical trials but it’ll take a while for those to fully pan out.

        Trivalent seasonal influenza vaccines include two influenza A subtype viruses (H1N1 and H3N2) and one influenza type B virus. Influenza virus strains were selected based on the influenza vaccine production method: egg-based and cell- or recombinant-based.

        As a result of the meeting with the federal partners, the FDA recommends that the trivalent formulation of egg-based influenza vaccines for the 2025-2026 U.S. influenza season contain the following:

        - an A/Victoria/4897/2022 (H1N1)pdm09-like virus;
        - an A/Croatia/10136RV/2023 (H3N2)-like virus; and
        - a B/Austria/1359417/2021 (B/Victoria lineage)-like virus.
        

        The FDA recommends that the trivalent formulation of cell- or recombinant-based influenza vaccines for the 2025-2026 U.S. influenza season contain the following:

        - an A/Wisconsin/67/2022 (H1N1)pdm09-like virus;
        - an A/District of Columbia/27/2023 (H3N2)-like virus; and
        - a B/Austria/1359417/2021 (B/Victoria lineage)-like virus.
