Advantages and a non-existent threat

Utilizing an adjusted odds ratio, the researchers discovered that vaccination decreased the chance of creating lengthy COVID with a number of signs by 57 p.c, and decreased the chance of creating lengthy COVID with two or extra signs by 73 p.c. Vaccination previous to an infection was additionally linked to a 75 p.c discount in threat of creating lengthy COVID that impacted day-to-day functioning. The authors be aware that the estimates of safety are doubtless underestimates as a result of the calculations don’t account for the truth that vaccination prevented some kids from getting contaminated within the first place.

“Our findings recommend that kids ought to keep updated with present COVID-19 vaccination suggestions as vaccination not solely protects in opposition to extreme COVID-19 sickness but additionally protects in opposition to [long Covid],” the authors conclude.

In a second brief report in JAMA Community Open, researchers helped dispel concern that the vaccines might trigger sudden cardiac arrest or sudden cardiac demise in younger athletes. That is an unproven declare that was fueled by anti-vaccine advocates amid the pandemic, together with the brand new US Well being Secretary and long-time anti-vaccine advocate Robert F. Kennedy Jr.

Whereas previous analyses have failed to find a link between COVID-19 vaccines and sudden cardiac deaths, the brand new research took a broader method. The research, led by researchers on the College of Washington, checked out whether or not the variety of sudden cardiac arrests (SCA) and sudden cardiac deaths (SCD) amongst younger athletes modified in any respect throughout the pandemic (2020–2022) in contrast with prior years (2017–2019). The researchers drew information from the Nationwide Heart for Catastrophic Sports activities Harm Analysis. In addition they collected medical information and post-mortem experiences on circumstances amongst aggressive athletes from the youth, center college, highschool, membership, school, or skilled ranges who skilled sudden cardiac arrest or demise at any time.

In all, there have been 387 circumstances, with no statistically vital distinction within the variety of circumstances within the years previous to the pandemic (203) in contrast with these throughout the pandemic (184).

“This cohort research discovered no improve in SCA/SCD in younger aggressive athletes within the US throughout the COVID-19 pandemic, suggesting that experiences asserting in any other case have been overestimating the cardiovascular threat of COVID-19 an infection, vaccination, and myocarditis,” the authors conclude.
