Fourth Pfizer Dose Is Insufficient to Ward Off Omicron, Israeli Trial Suggests (bloomberg.com) 173

Posted by BeauHD from the better-than-nothing dept.
A fourth dose of the Pfizer-BioNTech vaccine was insufficient to prevent infection with the omicron variant of Covid-19, according to preliminary data from a trial in Israel released Monday. Bloomberg reports: Two weeks after the start of the trial of 154 medical personnel at the Sheba Medical Center in Tel Aviv, researchers found the vaccine successfully raised antibody levels. But that only offered a partial defense against omicron, according to Gili Regev-Yochay, the trial's lead researcher. Vaccines which were more effective against previous variants offer less protection with omicron, she said. Still, those infected in the trial had only slight symptoms or none at all.

Israel started rolling out the fourth dose of the vaccine to the over-60s and immunocompromised in late December amid a surge in cases. Since then, more than half a million Israelis have received the extra dose, according to the Health Ministry. The decision to give the fourth vaccine to the most vulnerable was the correct one, Regev-Yochay said at a virtual press conference, since it may have given additional benefit against omicron. But she added the results didn't support a wider rollout to the whole population.

        I'm conflicted on this. People who get indoctrinated into cults are usually seen as victims, people we should help. Is anti-vaxx a new kind of cult, based around Facebook? A kind of stochastic cult where you can't point to specific leaders or organizations, but it's effective none-the-less.

        On the other hand, I don't want to get COVID so I have very little tolerance for such people being around me.

        • Victims, sure I get your point. Cult members tend to be people with poor critical thinking skills. Cults can be dangerous though, not just to the "victims", but also to society in general. If the victims are a threat they still need to be treated as such.

Whereas today, not only can we develop a vaccine for a coronavirus, we developed 6 different Covid vaccines in less than a year (J&J, Moderna, Pfizer, Astrazeneca, Sputnik, Sinovac) and distributed them throughout the world.

    It literally says right in the summary that it offers partial defense. All vaccines offer partial defense. There's no such thing as a perfect vaccine. This research is more useful in the sense that it shows that another booster this early isn't going to help. Meaning there's no reason to put additional strain on the vaccine supply to do fourth shots Because by the time it would be worth doing that we will likely have an omicron specific vaccine.

    The 24/7 news cycle has well and truly borked our entire national discourse. It means that whoever gets their headlines out first and flashiest is the one who reaps the rewards. As a result I have read a 50/50 mix that omicron is nothing to worry about and that we're all going to die sometime later this week. And as long as the clicks keep coming it's all good.

    Keep calm. Wear your mask. Wear the best mask you can get. Remember that the best mask is the one that you will wear. And get your three shots. Don't go looking door knobs and don't go to clubs and parties. If you're going to hang out with people hang out with people who are also vaccinated.

    Remember that if nothing else the first two variants and the flu are still out there and people can still get sick from them especially people who refuse to get vaccinated and if you can avoid giving those fools the virus maybe you can keep a few more people out of the hospital while we wait for this surge to abate. I just read a story about a doctor having to take a critical cancer patient who is probably going to die out of the ICU to make room for an unvaccinated covid patient. Yeah the cancer patient was going to die but they could have had a slim chance at life and maybe a more comfortable death. I can't get those people vaccinated for bumping people out of ICU beds but I can't at least prevent a few people from getting covid should I happen upon it myself in my thrice backed state of being.
    • Are the vaccines to date just not properly targeted for Omicron? Or is this the maximum level of defense that our immune system has to offer even if it is fully prepped?

      The Omicron wave does pass after a couple weeks, which means most people aren't immediately getting re-infected with it, or failing to clear it from their system in the first place.

        Omicron mutated enough that the antibodies developed against the vaccine (and earlier variants) are much less effective. There's no reason to believe an updated vaccine would not produce more targeted defenses, but, like Delta, Omicron might reproduce so rapidly that it wouldn't be as effective vs. infection when antibody levels declined (ramping them back up would take longer than it took to develop the infection), even if it reduced deaths and hospitalizations dramatically (because memory B cells could pump out the antibodies reactively much faster than the weeks it takes to become hospitalized or die).
      • All of the vaccines to date I’m aware of, all that are available for public use in America anyhow, are all geared to the original strain and not even alpha much less delta or omicron. Typically noticeable reinfection only occurs with a different variant either after vaccination or getting sick the hard way. Note however that the most effective vaccines actually provide more and additional benefit to natural immunity through infection so it’s best to get vaccinated.
    • There's not much to go on but I found this additional info that suggests the fourth shot didn't perform measurably better than the control group:

      Regev-Yochay noted that only slightly fewer people who received the fourth dose caught coronavirus than those in a control group, who were fully vaccinated with two shots in the last two months or three shots.

      No numbers were shared during the briefing because the infections were so close to receiving the fourth dose; "they do not shed light but are only confu

  • Last I checked, vaccine efficacy was defined in terms of the rate of infections prevented not in terms of hospitalization prevented. So first of all, we are lowering the bar a lot.

    Secondly, if vaccines do little to prevent the spread of the disease then getting vaccinated is mostly a personal decision. Forcing other people to get vaccinated will not lower your probability of ending up infected or in hospital.

    Thirdly, even if the vaccine reduces your chances of landing in hospital you have to remember that a
