Update: The J&J Vaccine Pause Probably Had No Effect on Vaccine Hesitancy

A new study suggests that the CDC's pause in administering the Johnson & Johnson vaccine had little to no effect on attitudes toward vaccination. Here are the results of a survey that spans before, during, and after the pause:

Before the pause, 60% of the respondents had either gotten vaccinated or wanted to as soon as possible. After the pause, that number was 63%. The percentage who wanted to wait until "after most people I know" stayed the same, as did the number of people who flatly didn't want it.

The authors also break down the results by demographic group, and there's not a single group that's more vaccine hesitant after the pause. Their conclusion:

Our survey suggests that awareness of the J&J pause was extremely high. Despite this, vaccine hesitancy/resistance did not increase for responses received after the pause, and our analysis of repeat respondents suggests a small but systematic shift decrease, largely because a fair number of people who were vaccine hesitant in early April were vaccinated by late April. In short, it seems very unlikely that the pause had major negative effects on vaccine attitudes.

My update to Wednesday's post about the J&J pause points in the same direction. The immediate decline in vaccination rates after the pause was due mostly to a decline in J&J vaccines, as you'd expect, and the subsequent smaller decline in the overall vaccination rate was most likely because we had vaccinated nearly everyone who was enthusiastic and were now entering a new phase that required more work to persuade people to get shots.

For now, then, I've changed my mind. It appears as if the J&J pause, regardless of whether it was right or wrong, probably had little to no effect on vaccine resistance.

    This teaches us that not every doomsayer is a Cassandra. One of the warning lights in the earlier post's study is the implausible magnitude of the effect.

    The pause was always the right decision: If something serious had been discovered while not making that pause it would have been perceived as a cover up and the effects of that on vaccine hesitancy would be of an altogether different order of magnitude.

    "MIAMI — A fifth-grade math and science teacher peddled a bogus conspiracy theory on Wednesday to students at Centner Academy, a private school in Miami, warning them that they should not hug parents who had been vaccinated against the coronavirus for more than five seconds because they might be exposed to harmful vaccine shedding."

    You watching the drama in Brazil's rejection of Sputnik V vaccine? https://bityl.co/6ea4

    The article links up to Brazil's regulatory body doing a video defending its decision by showing Russia's own documents. Skip to 11:46 in the video: https://ytube.io/3HQX

    This, a month after Slovakian officials complained that the shipment they received was of a different dose than what was used in testing, published in the Lancet.

    Almost no one trusts Russia's vaccine, and it has everything to do with the secrecy surrounding its vaccine data and its response to criticism.

    "A recent survey by the Globsec research group found that, among those willing to be vaccinated, only 1 percent of Poles and Romanians and 2 percent of Lithuanians would choose Sputnik over American and European brands. Even in Hungary, the lone European Union member to start inoculating its citizens with Russia’s product, only 4 percent want Sputnik V." -- https://bityl.co/6ean

    Now, if you want to drive vaccine hesitancy, do what Putin does: Be as opaque as possible. But, if you want to avoid driving vaccine hesitancy, be as transparent as possible.

      Trouble in paradise? The autocrat lovefest of Jair & Vlad hits a shoal.

      Well, this is just a new reason for Glemm Greemwald to hit at Bolsonaro as a dangerous fascist while further redeeming Pooty Poot.

    I still expect the J&J Vaccine Pause to lead lamestream media write-ups of the scandals of El Pepe Maximo's First 100 Days, right after the Neera Tanden Nomination Disaster, & just ahead of Major Biden's teething issues & Jen Psaki's attempted bribery of the White House Press Corps with homemade chocolate cookies.

    It seems so long since we had an honest & operationally sound White House, but it's only been four months.

      Tanden, Bicycle... 100 Scandals in 100 Days. by Chris Cillizza

      "Opening before President Biden had sworn his oath, & even prior to Donald Trump & the Republicans's last-ditch effort to remake the election with the Congressional certification standoff on January 6, the 46th presidential regime of Joseph Robinette Biden & Kamala Devi Harris has been dogged by missteps both avoidable & predictive of continued disorder. From the expected & expectedly ill-advised elevation of Clinton surrogate Neera Tanden to the Office of Management & Budget, to questions over the confidence with which Biden could operate his Peloton without indulging compromise by foreign intelligence services, we as a nation knew we were entering unchecked territory. Not only were we going to see our first woman executive officer in the federal government, & beyond that our oldest first term president by four years, but a White House on already shaky ground after the contentious transition marked by legal challenge & physical conflict...."

          So. Many. Scandals.

          Seuss. Tuber... uh... tubers. Just this week, displaying his dementia in its most obvious way, wandering off from the walk to Marine 1 to pick a dandelion fir his False Doctor wife.

          Kamala's booksales gaming with issue of her children's book to unaccompanied minors at the border. Her stepdaughter's couture contract as both on camera talent & workshop designer. Her husband deciding he's no longer Doug anymore, but Douglas. (Being First Doug was too close to being White Doug in the Hangover?)

          1. MontyTheClipArtMongoose

            I agree, but there are just so many scandals in this American regime born under a bad sign.

    I wonder how things will work out regionally. Here in California we have some counties that are already approaching the herd immunity threshold, at least with regard to people over 16. Marin County has over 80% with at least one shot. Kings County only has about 34%. Will the Counties that have a vaccinated population have very few cases while the unvaccinated counties are still Covid hot spot? If so, will that spur people to get the vaccine? How will that work with states that have a majority of people unvaccinated?

  7. Jerry O'Brien

    The number of unvaccinated people in the United States has dropped so rapidly that this decreasing number of eligibles is itself driving down the absolute number of vaccinations given every week. No need even to talk about how you've picked off the most enthusiastic and now it's harder to persuade people. There just aren't as many people left who need the vaccine.

    Thanks for the update.
    There was also a report that some of the unexpected side effects to J&J vaccinations reported earlier, the dizziness and fainting right after the vaccine, were due to nervousness--and that is also a more common reaction among younger cohorts. And in some cases, that might just be due to relief.

    I've seen reports that in juggling vaccinations, some places now dealing with expiration dates. All the more reason to send vaccinations out to other countries.

    1. Crissa

      I had the opposite! I haven't received a vaccine without then suffering a seizure since I was 6. And this time... Nothing!

      Of course, they let me lie down and talked me through it. And I had a vigorous walk through the maze of the line at the mass vaccination clinic ahead of time that definitely helped.

    And again, there are significant population numbers that aren't hesitant but need help over coming barriers to vaccination: they need to know: no cost, where to get it, how to sign up, time off work, sometimes in a different language.

    This is different qualitatively from persuation and one reason why I feel strongly that we can get 75% population immunity which should be enough for herd immunity.

  10. Midgard

    Time to get rid of mask mandates. If people don't want to get it and get sick, so be it. Glad some northeastern states are getting it.

    Fwiw, my 21 year old cousin waited for the jj one so yeah, I expect a mini burst in vaccination.

    Would you like to hear another horror story about the side effects experienced after getting a second dose of covid-19 vaccine? Well, too bad, I don't have one. My second shot of Pfizer was twenty-four hours ago, and the sore shoulder is once again the whole deal.

    1. MontyTheClipArtMongoose

      My injection site pain was worse the first time thru than the second.

      Pfizer was a smash.

      Vince Vaughn turning MAGA still surprises me.

      But, knowing that, & his Notre Dame fandom, surprised he wasn't at Amy Crate & Barrel's confirmation hearing to introduce her.

        That is maga??? Please. It's more wannabe tough man. Calling it anti-Semitic or homophobic based on catch phrases is lolz.

        What struck me was the complete association of conservative virtue with brutalization, where anything not brutalizing is 'far-left'.

        It's straightforward Nazism and crass juvenility. They're almost always unable to resist expressing the emotional maturity of their first boner, in any situation, as on that occasion when our prior president assured the world his was really enormous, as if anyone doubted it.

      Ever read Marx's Jewish question??? Homophobia, self-hatred all rolled into a nice package. Marx advised Lincoln to get rid of negro slaves so white southerners could have revolutions.

      History is not always kind to dialectics. Conservatives forget this. Who ran money for peak era Catholic dominance in western Europe??? I think Hutton Gibson may not like that answer.

    Is every idiot who refuses a vaccination going to get a story in the media? Let it go. It really doesn't help to write about them or interview them.

    "The reluctance of police to get the shots threatens not just their own health, but also the safety of people they’re responsible for guarding, monitoring and patrolling, experts say."

    https://www.washingtonpost.com/health/2021/05/02/police-low-vaccination-rates-safety-concerns/

    Stop reporting on their foolishness.

      "every idiot"
      Hey, the "Eleet Media" got into the habit of visiting rural diners for the last five years, to interview and marvel over the Trumpist hicks. That's going to be hard to break.

      As long as the Volstead Act doesn't maintain in Ohio, the Sulzberger Advertiser will never stop looking for Trump voters.

      They will also never start looking for Biden voters.

      Today we who don't live in Ohio are all Manhattan lesbian Trump supporters.
