COVID-19 "natural immunity"

Which is best, vaccine-induced immunity, “natural immunity,” or “super immunity” to COVID-19?

Those opposed to public health interventions to slow the spread of COVID-19, including masks, "lockdowns," and vaccine mandates, are hyping "natural" immunity again as somehow "superior" to vaccine-acquired immunity. It's a deceptive simplification of a complex issue.

John Ioannidis uses the Kardashian Index to attack critics of the Great Barrington Declaration

This isn't a title that I ever thought I'd use or a post that I ever thought I'd write, but John Ioannidis has really done it. He's incompetently used the Kardashian index to attack John Snow Memorandum signatories and argue that the Great Barrington Declaration signatories, who argue for a "natural herd immunity" approach to the COVID-19 pandemic, are the underdogs who...

How the DMED works

Antivaxxers misuse the Defense Medical Epidemiology Database to demonize COVID-19 vaccines

Over the last couple of weeks, a claim that the Defense Medical Epidemiology Database (DMED) shows that COVID-19 vaccines have caused a massive increase in cancer, neurological, and cardiovascular diseases in military personnel has gone viral. A closer look shows that the increases are almost certainly spurious and due to underreporting in previous years.

Oz challenges Fauci to debate

“Debate me, bro!”: Debate challenges by science deniers in the age of COVID-19

Quacks, science deniers, and conspiracy theorists love to challenge doctors, scientists, and science communicators to "live public debates" over the science they deny. I just say no, and you should say no too if you are in a position to receive such a challenge.

Brownstone Institute

The “spiritual child of the Great Barrington Declaration” promotes antivaccine misinformation

The signatories of the Great Barrington Declaration and its "spiritual child" the Brownstone Institute, swear up and down that they are not anttivaccine. If that's so, why are Brownstone-affiliated academics spreading antivaccine misinformation in Uganda?

Rubber Duck quack

Why are physicians threatened by efforts to report doctors to their state medical board for COVID-19 misinformation?

It's not "cancel culture" to delicense physicians promoting dangerous misinformation about COVID-19. It's quality control. Why do so many physicians think it is?

Substack

Substack: Where quacks and antivaxxers all go now

With social media companies like Twitter and Facebook/Meta deplatforming those spreading misinformation, COVID-19 quacks, antivaxxers, and conspiracy theorists are flocking to Substack, where they can monetize their misinformation while Substack profits.

Everything old is new again

Since the pandemic hit, I've frequently said things like, "Everything old is new again", referring to the antivaccine movement in the age of COVID-19. As 2022 dawned, I thought I'd expand a bit on what I mean. Is there a term for déjà vu, but what I'm seeing now is amplified a thousand-fold? Proponents of science-based medicine have been warning us for...

VAERS database

As 2021 shambles to a close, the misuse of VAERS by antivaxxers continues apace

Misuse of the VAERS database to spread fear, uncertainty, and doubt about vaccines has been a favorite technique of antivaxxers for decades. Unfortunately, 2021 was the year when this particular antivax trope was turbocharged, and public health messaging seemed powerless to counter it.

Carl Sagan

John Ioannidis and the Carl Sagan effect in science communication about COVID-19

We have been critical about John Ioannidis over a number of his statements about the COVID-19 pandemic. Now he's done it again, producing a poor-quality paper whose unwritten assumptions suggest that the Carl Sagan effect, in which scientists are penalized professionally by their peers for becoming popular science communicators, still holds considerable sway in science and medicine.
