I'm not sure how that contradicts what I said? Most of the people in the COVID-19 group tested positive before the vaccines were approved in December 2020. Yes, they might have been vaccinated afterwards, but my point is they did not have vaccine-induced antibodies at the time of their infections.
That's the pool of 60+ year-old veterans who were selected after testing positive and then subsequently monitored for one year.
It is likely that many were vaccinated during the 1-year period from Jan 2021 - Jan 2022.
e.g. as of July 2021, the VA % vaccinated was about 50%, https://www.usatoday.com/story/news/nation/2021/07/26/va-man...
We know that mRNA vaccines have resulted in negative cardiac consequences in some patients, although that has mostly been in younger men.
