Many criticized the article below co-authored by Jay Bhattacharya, who also co-wrote the Great Barrington Declaration.
But I haven't seen a detailed explanation of why the article was wrong + dangerous. So I'll give one here

It was clear Bhattacharya + others were wrong long before the recent resurgence of COVID-19 in India.
So this is not just "hindsight is 20/20."

Imagine the spread of SARS-CoV-2 as an accelerating car.
Some brakes help slow the car, such as masks, social distancing, contract tracing, etc.
But even without brakes, the car will eventually start slowing down on its own; that's herd immunity.

Once you have enough people immune to infection at herd immunity (whether immune by prior infection or vaccination), you can stop using the brakes and the car still won't accelerate.
Bad idea to release the brakes too early without herd immunity.

Bhattacharya doesn't like various brakes for ideological reasons (there's a reason he goes to right-wing outlets a lot).
So he exaggerated how close India was to herd immunity.
"a near majority of the population has developed immunity to the virus"

That's consistent with Bhattacharya exaggerating the number of infections for over a year.
It's convenient for him in a number of ways, such as allowing him to give COVID-19 fatality rates so low they're impossible.

Bhattacharya accepts models when they're convenient for his ideology, + ditches them otherwise. He mixed that with his usual bad extrapolations from non-representative samples.
Anyway, India was nowhere near ~50% of their population being infected.

So the car is facing the edge of the cliff.
Bhattacharya (falsely) tells the driver they are very close to not needing the brakes anymore to slow down the car.
What could be worse than that?
Well... Bhattacharya telling them brakes don't work. 🤦♂️

I'm not going to rehash the reasons why limiting people being near each other limits transmission of a virus that spreads by people being near each other.
Not like Bhattacharya + his fans will learn at this point anyway.

One of Bhattacharya's proposed solutions is to reserve vaccinations for people who were not infected before.
That would be an interesting point,... except that he can't help but add to that his distortions of immunology and vaccines.

There's good reason to think that vaccines will work better than "natural" infection with SARS-CoV-2.
There's also a chance they may improve the immune response of those previously infected.
There are other issues as well.

For herd immunity, we want antibodies + B cells / plasma cells that prevent re-infection; i.e. we want neutralizing antibodies that cause sterilizing immunity.

Unfortunately:
- not all antibodies are neutralizing
- neutralizing antibodies can wane, allowing for re-infection
- SARS-CoV-2 mutations could evade antibodies, or result in a more contagious form needing more people immune for herd immunity
Etc.

Vaccines can help with this by increasing levels of neutralizing antibodies or addressing variants (see part 11/Y).
Conversely, allowing many infections facilitates the evolution of harmful mutants.

So who in their right mind would advocate for taking off brakes to allow for many infections?
Jay Bhattacharya, and his Great Barrington Declaration group.
At this point, he's just sabotaging the brakes for India and pushing the car off the cliff.

But if you're going to push the car off the cliff, you may want to downplay how dangerous that is.
So Bhattacharya reaches into his usual bag of tricks for doing that. For example, citing Ioannidis' work on fatality rates:

But Ioannidis' poor work leads to fatality rates so impossibly low that they require more people are infected than actually exist (Bhattacharya did the same in part 6/Y).
One of the places that happens is... India.

And of course, Bhattacharya knowingly abuses the misleading "infection survival rate" framing.
Easy to cover up how bad 600,000 deaths are by saying '99.4% survival rate', without mentioning 100 million infected.

I value the feelings of deniers like Bhattacharya less than the lives they put at risk.

On vaccinating infected people (see part 10/Y):
- vaccines help infected folks
- other priorities, like vaccinating the elderly + those in regular contact with the infected (ex: healthcare staff)
- risk of doses expiring waiting to find non-infected

And Bhattacharya's January 2021 article was in line with horrible advice he's given to India *for months.*
For example, before there was a vaccine he advocated for herd immunity via people getting infected.

Yet Bhattacharya + his Great Barrington Declaration team refuse to admit to they were wrong.
That's in contrast to those with integrity like Monica Gandhi, who apologized for what she said on India + herd immunity.

The results in 7/Y showing ~24% infected, were out by February 4.
I re-tweeted them on February 10.
So if Bhattacharya bothered to pay attention, he had weeks to correct his dangerous mistake + warn people.
Yet he didn't.

So hopefully this thread explained some reasons why so many experts were rightly upset with Jay Bhattacharya.
He's been ludicrously irresponsible during this pandemic.
