The Food and Drug Administration is looking for to drastically change procedures for testing vaccine security and approving vaccines, based mostly on unproven claims that mRNA-based COVID-19 vaccines triggered the demise of a minimum of 10 kids.
The company detailed its plans in a memo launched to employees on Nov. 28, 2025, which was obtained by a number of information shops and revealed by The Washington Post.
Citing an inner, unpublished evaluate, the memo, written by the company’s prime vaccine regulator, Vinay Prasad, attributes the kids’s deaths to myocarditis, an irritation of the center muscle. And it says the deaths had been reported to the Vaccine Adverse Event Reporting System, or VAERS, however offers no proof that the vaccines triggered the deaths.
The demise of kids as a consequence of an unsafe vaccine is a severe allegation. I’m a pediatric heart specialist who has studied the hyperlink between COVID-19 vaccines and heart-related unwanted effects akin to myocarditis in kids.
To my data, research thus far have proven such unwanted effects are uncommon, and extreme outcomes much more so. However, I’m open to new proof that might change my thoughts.
But with out enough justification and stable proof, limiting entry to an authorized vaccine and altering well-established procedures for testing vaccines would carry severe penalties. These strikes would restrict entry for sufferers, create roadblocks for firms and worsen mistrust in vaccines and public well being.
In my view, it’s necessary for folks studying about these FDA actions to grasp how the proof on a vaccine’s security is usually assessed.
Determining reason behind demise
The FDA memo claims that the deaths of those kids had been instantly associated to receiving a COVID-19 immunization.
From my perspective as a clinician, it’s terrible that any baby ought to die from a routine vaccination.
However, well being professionals like me owe it to the general public to uphold the very best attainable requirements in investigating why these deaths occurred. If the FDA has proof demonstrating one thing that nationwide well being companies worldwide have missed – widespread baby deaths as a consequence of myocarditis attributable to the COVID-19 vaccine – I don’t doubt that even probably the most pro-vaccine doctor will hear. So far, nevertheless, no such proof has been introduced.
While a demise logged in VAERS is a place to begin, by itself it’s inadequate to conclude whether or not a vaccine triggered the demise or different medical causes had been accountable.
To show a causal hyperlink, FDA employees and physicians should align the VAERS report with physicians’ assessments of the affected person, in addition to knowledge from different sources for monitoring vaccine security. These embrace PRISM, which logs insurance coverage claims knowledge, and the Vaccine Safety Datalink, which tracks security indicators in digital medical information.
It’s recognized that the majority deaths logged solely in VAERS of kids who not too long ago acquired vaccines have been incorrectly attributed to the vaccines – both by chance or in some instances on goal by anti-vaccine activists.
Heart-related unwanted effects of COVID-19 vaccines
In his Substack and Twitter accounts, Prasad has mentioned that he believes the speed of extreme cardiac unwanted effects after COVID-19 vaccination is severely underestimated and that the vaccines must be restricted way over they at present are.
In a July 2025 presentation, Prasad quoted a danger of 27 instances per million of myocarditis in younger males who acquired the COVID-19 vaccine. A 2024 evaluate prompt that quantity was a bit decrease – about 20 instances out of 1 million folks. But that very same examine discovered that unvaccinated folks had higher danger of coronary heart issues after a COVID-19 an infection than vaccinated folks. In a unique examine, individuals who received myocarditis after a COVID-19 vaccination developed fewer issues than individuals who received myocarditis after a COVID-19 an infection.

Existing vaccine security infrastructure within the U.S. efficiently identifies risks posed by vaccines – and did so throughout the COVID-19 pandemic. Today, most COVID-19 vaccines within the U.S. depend on mRNA expertise. But as vaccines had been first rising throughout the COVID-19 pandemic, two pharmaceutical firms, Janssen and AstraZeneca, rolled out a vaccine that used a unique expertise, referred to as a viral vector. This sort of vaccine had a really uncommon however real security drawback that was detected.
VAERS, the Vaccine Safety Datalink, scientific investigators within the U.S. and their European counterparts detected that these vaccines did prove to trigger blood clotting. In April 2021, the FDA formally beneficial pausing their use, and so they had been later pulled from the market.
Death as a consequence of myocarditis from COVID-19 vaccination is exceedingly uncommon. Demonstrating that it occurred requires proof that the individual had myocarditis, proof that no different cheap reason behind demise was current, and the absence of any further reason behind myocarditis. These elements can’t be decided from VAERS knowledge, nevertheless – and thus far, the FDA has introduced no different related knowledge.
A problematic imaginative and prescient for future vaccine approvals
Currently, vaccines are examined each by seeing how properly they forestall illness and by how properly they generate antibodies, that are the molecules that assist your physique combat viruses and micro organism.
Some vaccines, such because the COVID-19 vaccine and the influenza vaccine, should be up to date based mostly on new strains. The FDA typically approves these updates based mostly on how properly the brand new variations generate antibodies. Since the earlier technology of vaccines was already proven to forestall an infection, if the brand new model can generate antibodies just like the earlier one, researchers assume its means to forestall an infection is comparable too. Later research can then take a look at how properly the vaccines forestall extreme illness and hospitalization.
The FDA memo says this method is inadequate and as an alternative argues for changing such research with many extra placebo-controlled trials – not only for COVID-19 vaccines but in addition for broadly used influenza and pneumonia vaccines.
That could seem cheap theoretically. In observe, nevertheless, it isn’t real looking.
Today’s influenza vaccines should be modified each season to mirror mutations to the virus. If the FDA had been to require new placebo-controlled trials yearly, the vaccine being examined would turn out to be out of date by the point it’s authorized. This could be an enormous waste of time and assets.
Also, detecting vaccine-related myocarditis on the low price at which it happens would have required scientific trials many instances bigger than those that had been carried out to approve COVID-19 mRNA vaccines. This would have price a minimum of thousands and thousands of {dollars} extra, and the delay in rolling out vaccines would have additionally price lives.
Placebo-controlled trials would require evaluating individuals who obtain the up to date vaccine with individuals who stay unvaccinated. When an older model of the vaccine is already obtainable, this implies purposefully asking folks to forgo that vaccine and danger an infection for the sake of the trial, a observe that’s broadly thought of unethical. Current scientific observe is that solely a brand-new vaccine could also be in contrast in opposition to placebo.
While suspected vaccine deaths ought to completely be investigated, stopping a vaccine for inadequate causes can result in a big drop in public confidence. That’s why it’s important to totally and transparently examine any claims {that a} vaccine causes hurt.
Vaccine vs sickness
To precisely gauge a vaccine’s dangers, it’s also essential to match its unwanted effects with the results of the sickness it prevents.
For COVID-19, knowledge persistently exhibits that the illness is clearly extra harmful. From Aug. 1, 2021, to July 31, 2022, greater than 800 kids within the U.S. died as a consequence of COVID-19, however only a few deaths from COVID-19 vaccines in kids have been verified worldwide. What’s extra, the illness causes many extra heart-related unwanted effects than the vaccine does.
Meanwhile, in depth proof exhibits that COVID-19 vaccination reduces the chance of hospitalization by greater than 70% and the chance of extreme sickness in adolescent kids by 79%. Studies additionally present it dramatically reduces their danger of creating lengthy COVID, a situation during which signs akin to excessive fatigue or weak spot persist greater than three months after a COVID-19 an infection.
Reporting solely the vaccines’ dangers, and never their advantages, exhibits only a small a part of the image.
