Also there were no vaccines trials in India in 2020! 😂😂😂
The author of the chicken research himself says in the above link that we still need to vax. Which kinda deflates the use of his research for your position.
I suspect you didn't read his link..so here is what he said..
"The paper has gone viral because some people are using it to stoke paranoia that the COVID-19 vaccines will cause the virus to evolve in the direction of even more severe variants.Doctors have told me that patients are using the paper to justify their decision to not get vaccinated. Some pundits are even using it to urge an end to vaccination campaigns in order to prevent the sort of viral evolution we were studying in chickens.
"Nothing in our paper remotely justifies an anti-vaccine stance."
He is doing nothing more than keeping himself from being a victim of the vaccine jihad. The actual published research says otherwise.
