Covid-19 Vaccine?: Maybe, Maybe Not

professor, equationsThe governments “top men” are working on it

Peter Doshi, an associate editor at British Medical Journal, is not favorably impressed with the recent vaccine trial announcements. “90% effective.” “95% effective!”

Coronavirus guru Anthony Fauci assures us that a coronavirus vaccine will only be FDA-approved if it’s “safe and effective.”

From Doshi:

But what will it mean exactly when a vaccine is declared “effective”? To the public this seems fairly obvious. “The primary goal of a covid-19 vaccine is to keep people from getting very sick and dying,” a National Public Radio broadcast said bluntly.

Peter Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine in Houston, said, “Ideally, you want an antiviral vaccine to do two things . . . first, reduce the likelihood you will get severely ill and go to the hospital, and two, prevent infection and therefore interrupt disease transmission.”

Yet the current phase III trials are not actually set up to prove either. None of the trials currently under way are designed to detect a reduction in any serious outcome such as hospital admissions, use of intensive care, or deaths. Nor are the vaccines being studied to determine whether they can interrupt transmission of the virus.

 

elderly man, face maskDo you ever wonder why we didn’t see widespread use face masks during a typical flu season?
Switching gears to the flu vaccine for a minute. The flu vaccine’s been a godsend in preventing influenza death among the frail elderly, right? Not so fast there, pardner. Doshi again:

But the truth is that the science remains far from clear cut, even for influenza vaccines that have been used for decades. Although randomised trials have shown an effect in reducing the risk of symptomatic influenza, such trials have never been conducted in elderly people living in the community to see whether they save lives.

Only two placebo controlled trials in this population have ever been conducted, and neither was designed to detect any difference in hospital admissions or deaths.

Moreover, dramatic increases in use of influenza vaccines has not been associated with a decline in mortality.

The Moderna and Pfizer trials enrolled 30,000 and 44,000 participants, respectively. That sounds like a lot of people to be vaccinated. But they only vaccinate half the folks. The other have serve as a control group. Next, the investigators track the occurrence of coronavirus events over time, then compare the two groups. An “event” may be anything from a cough plus positive COVID-19 PCR test, to hospitalization or death. Of course, they also look at potential adverse effect of vaccination, comparing the two groups.

The trials aren’t going to give us good information on COVID-19 hospitalizations and death rates because those outcomes are so infrequent. Most people with symptomatic COVID-19 experience only mild symptoms; there are relatively few cases of serious disease in a general population of 30,000.

  1. Any human merely being, or even a reader of this blog, who still has ANY faith in vaxxing has failed to watch the dead and dying infants in the movie VAXXED11
    I was shocked and appalled beyond belief (and I’m an antivaxxer supposedly aware and awake)
    Spoiler (for some folks out there): Dr Wakefield is a HERO

    • Too true, Mike. Western medicine has been through some dark time (when bleeding was in favor, for example) when dogma and superstition, rather than empirical science, governed practice. I suspect we are in another one now, with the heavy emphasis on unproven public health measures such as vaccines, lockdowns, low fat diets and fluoridation.
