don't your links directly contradict the article that was posted?
The article states infection from COVID seems to produce better immunity than the vaccines.
- Being previously infected with COVID-19 confers greater immunity than the COVID-19 vaccines
- Being previously infected with COVID-19 and being vaccinated confers >2x the immunity than being previously infected alone
The posted article seems to agree as well, but it's unfortunate many folks seem to just be taking the headline at face value:
"The researchers also found that people who had SARS-CoV-2 previously and then received one dose of the Pfizer-BioNTech messenger RNA (mRNA) vaccine were more highly protected against reinfection than those who once had the virus and were still unvaccinated."
