Extremely and utterly emphatically no. This is the most healthy population and contains genetic outliers as it relates to the level of athletic talent to ever be birthed. But hey don't trust my word for it.
Long term effects of COVID on players in the big 5+WNBA sports leagues is at a crazy small rate.
Joint Statement on behalf of MLB, MLS, NBA, NHL, NFL and WNBA
Of the 786 cases 4.716 (so 5) athletes had evidence of inflammatory heart disease. And of those 5, their recovery continued the further they got away from original infection. (Some doctors in the SportsMed space are nuts and complete covidiots) Most rational folks in the industry look at what the Big 6 did when it came to contact tracing bracelets and isolation of unvaccinated players from meetings as extremely unnecessary especially as the infection rates of those vaccinated continued to climb. Leading the NFLPA and NFL to just say fuck it. But the CDC said fuck it like six months ago to, your vaccination status is no longer considered a control status.
But hey I just was the testing coordinator for a small sports league with over 600 athletes and I saw what the effects of our policy was.
ETA:
Just like when
@amlove21 and I said vaccinating Soldiers/Airmen/Marines/Sailors/Puddle Pirates/Star Trekkians was not only immoral but the wrong thing to do based on the science we had at the time "hey if you're really healthy, this will be the sniffles at worst". So the science may be still be out, but my huevos were telling me something in April 2020 that seems to be aligned with the science that has been coming out since last Summer.
