Here’s the clearest picture we have from actual data — not rumors — about serious adverse events (SAEs) after COVID-19 vaccination in U.S. military personnel, especially in the context of active service members and military health system reporting:

===== Boldest signal that has actually been studied is myocarditis (inflammation of the heart) — not thousands of events, but a small cluster seen after mRNA COVID-19 vaccines: =====
* A JAMA Cardiology research brief described cases of myocarditis in 23 generally healthy U.S. service members (median age ~25) who developed acute chest pain within about 4 days after vaccination with mRNA vaccines (Pfizer or Moderna). Most occurred after the second dose of the primary series. This was out of millions of doses given in the military population. siicsalud.com<ref>{{cite web|title=siicsalud.com|url=https://www.siicsalud.com/dato/resiic.php/167589|publisher=siicsalud.com|access-date=2025-12-20}}</ref>
* Earlier analyses also noted this finding: myocarditis was observed and reported among military members shortly after mRNA vaccination. JAMA Network<ref>{{cite web|title=JAMA Network|url=https://jamanetwork.com/journals/jamacardiology/fullarticle/2781601|publisher=JAMA Network|access-date=2025-12-20}}</ref>
* These reports are consistent with external civilian studies showing elevated myocarditis risk in young males after mRNA COVID-19 vaccines, including military-age demographics, although these events remain rare in absolute terms. AHA Journals<ref>{{cite web|title=AHA Journals|url=https://www.ahajournals.org/doi/10.1161/CIRCULATIONAHA.121.056135|publisher=AHA Journals|access-date=2025-12-20}}</ref>

Context & interpretation:
Myocarditis in this reporting is not common — it was a signal, not a widespread epidemic — and researchers highlight both the temporal association and the need for careful surveillance, but also that these events are uncommon relative to the massive number of doses administered. siicsalud.com<ref>{{cite web|title=siicsalud.com|url=https://www.siicsalud.com/dato/resiic.php/167589|publisher=siicsalud.com|access-date=2025-12-20}}</ref>

===== For military personnel specifically, most SAE data come through broad U.S. systems like VAERS (Vaccine Adverse Event Reporting System) or Defense Health Agency monitoring, not special stand-alone military registries, so: =====
* VAERS reports capture events after vaccination, but do not prove causation — meaning a report after a shot isn’t evidence the vaccine caused it. Further clinical review and epidemiologic study are needed to determine that. CDC<ref>{{cite web|title=CDC|url=https://www.cdc.gov/vaccine-safety-systems/vaers/index.html|publisher=cdc.gov|access-date=2025-12-20}}</ref>
* Independent fact-checks have flagged misuses of such data where people claim “hundreds of serious reactions among military veterans” from COVID shots — these claims misinterpret VAERS reports as causal. Science Feedback<ref>{{cite web|title=Science Feedback|url=https://healthfeedback.org/claimreview/unsupported-claim-that-covid-19-vaccines-caused-hundreds-of-serious-reactions-among-military-veterans-misuses-vaers-reports/|publisher=Science Feedback|access-date=2025-12-20}}</ref>

Because VAERS is a passive system that accepts all reports, both military and civilian data require contextual interpretation before concluding anything causal.

===== Even within military-aged populations: =====
* Real-world evidence — including in broader U.S. data — shows the risk of myocarditis or other serious outcomes is higher after COVID-19 infection itself than after vaccination. This has been seen in multiple civilian populations and likely applies to young service members as well. Wikipedia<ref>{{cite web|title=Wikipedia|url=https://en.wikipedia.org/wiki/COVID-19_vaccine|publisher=en.wikipedia.org|access-date=2025-12-20}}</ref>
* Other serious events (like Guillain-Barré, thrombosis) are very rare and have been reported at low frequencies in general vaccine surveillance, without clear large increases due to vaccination. CDC Archive<ref>{{cite web|title=CDC Archive|url=https://archive.cdc.gov/www_cdc_gov/coronavirus/2019-ncov/vaccines/safety/adverse-events.html|publisher=CDC Archive|access-date=2025-12-20}}</ref>

===== ✔ Serious adverse events among U.S. military personnel after COVID-19 vaccination do occur, but they are rare. =====
✔ Myocarditis — particularly in young men shortly after the second mRNA dose — has been documented and studied, but represents a tiny fraction of millions of doses. siicsalud.com<ref>{{cite web|title=siicsalud.com|url=https://www.siicsalud.com/dato/resiic.php/167589|publisher=siicsalud.com|access-date=2025-12-20}}</ref>
✔ VAERS data must be interpreted carefully and do not establish causation on their own. CDC<ref>{{cite web|title=CDC|url=https://www.cdc.gov/vaccine-safety-systems/vaers/index.html|publisher=cdc.gov|access-date=2025-12-20}}</ref>
✔ Overall safety surveillance — including CDC and FDA monitoring — views serious events as uncommon relative to the protective effects of vaccination against SARS-CoV-2 infection.

If you want, I can also dive into specific incidence rates from military vs. civilian cohorts (e.g., per 100,000 doses) or link to the primary studies so you can explore them directly.
