11 thoughts on “Biden Administration to Push For Covid-19 Vaccine Boosters

  1. I guess it’s better than nothing, but at this point, shouldn’t we be looking at intranasal and/or delta- or multivariant-targeted boosters, rather than just going for a third round with the original vaccine?Report

    1. I suspect the administration has some internal indication of when the BioNTech and Moderna vaccines will be fully licensed. At that point, a couple of things happen. (1) A booster dose of a licensed vaccine falls within the usual “off label” laws, and administering such w/o further FDA licensing doesn’t threaten providers’ medical licenses. (2) It makes approval of alternative vaccine tech more difficult. At least as I understand it, getting an EUA for such would require initial clinical testing that showed some significant improvement vs the fully-licensed mRNA vaccines: more effective, safer, less expensive, something.

      Right now, the administration “will announce” the desirability of boosters. Watch for it to happen right after the full licensing.Report

  2. Someone within the CDC releases their internal data (power-point presentation) in support of their claim that “the war has changed,” and it seems everyone just selects the bits that support their pre-existing position. Here is the entireity of what the CDC said about waning immunity:

    “Preliminary VE estimates assessing duration of protection for 2 doses of mRNA vaccines

    ▪ VISION (test negative design across 8 integrated healthcare systems), data through June 22, 2021
    – VE against hospitalization 88% (CI 86-90)
    – No evidence of waning immunity to 16 weeks post-2nd dose

    ▪ IVY3 (test negative design across 21 hospitals), data through June 2021
    – VE against hospitalization 87% (CI 85-97)
    – No evidence of waning immunity through 20 weeks post-2nd dose

    ▪ Healthcare personnel (test negative design across 33 sites), data to May 31, 2021
    – VE against symptomatic infection 90%
    – No evidence of waning immunity through 14 weeks post-2nd dose

    (CONFIDENTIAL – preliminary data, subject to change)”Report

  3. “The Biden administration is planning to announce that most Americans who have received the coronavirus vaccine will need booster shots to combat waning immunity and the highly transmissible delta variant that is sparking a surge in covid-19 cases, according to four people familiar with the decision.”

    Is anyone claiming that the surge in cases is due to declining immunity? I mean, if immunity will fall and we need boosters, that’s one thing, but this opening paragraph indicates something different.Report

    1. You may be parsing the sentence incorrectly. Try “to combat (waning immunity) and (the highly transmissible delta variant that is sparking a surge in covid-19 cases).”Report

        1. The other issue is the surge already peaked in the initial round of states and the Rt has dropped below 1. (Florida, Texas, Louisiana, Arkansas, and Missouri for example) Other states are surging (D.C., Dakotas, Indiana, Iowa, Maine, New Mexico, North Carolina, Ohio, Oregon, and Washington), with Rt 1.3 or more.

          Seems like we’ve seen this movie before. Cases go up, people pull back, cases peak and then government announces a policy change.Report

          1. Texas has peaked? News to me.

            I mean GOOD news, as our ICU’s are packed full and I know several people waiting on urgent surgeries.

            Oh, and we just re-ordered some mortuary trucks.Report
