COVID vaccines still protect against heart problems, large study finds
A study of over a million veterans confirms COVID-19 vaccination reduces all-cause cardiac events by nearly 24%, including heart attacks and cardiac death. While benefits remain strong, vaccine uptake has declined amid persistent anti-vaccine messaging. The FDA maintains its warnings about rare mRNA-related heart risks but has not identified new safety concerns outweighing cardiac protection. CDC reaffirms vaccination as the safest strategy to prevent severe outcomes, including hospitalization and death, for all ages 6 months and older.
What changed
New data from a JAMA Internal Medicine study reinforces the 24% reduction in cardiac events, with no conflicting evidence on vaccine efficacy.

COVID vaccines still cut heart risks by nearly 24% in major veteran study
confidence 98%A study of over a million veterans confirms COVID-19 vaccination reduces all-cause cardiac events by nearly 24%, including heart attacks and cardiac death. While benefits remain strong, vaccine uptake has declined amid persistent anti-vaccine messaging. The FDA maintains its warnings about rare mRNA-related heart risks but has not identified new safety concerns outweighing cardiac protection. CDC reaffirms vaccination as the safest strategy to prevent severe outcomes, including hospitalization and death, for all ages 6 months and older.
What's confirmed:
- COVID-19 vaccination is linked to a nearly 24% reduction in all-cause cardiac events, including heart attacks and cardiac death, in a study of over a million veterans.
- The FDA has not identified new safety concerns that outweigh the cardiac benefits of COVID-19 vaccines, though it continues to warn about rare heart risks tied to mRNA vaccines.
- CDC recommends COVID-19 vaccines for all individuals aged 6 months and older, emphasizing vaccination as the safest strategy to avoid hospitalizations, long-term health outcomes, and death.
- Three separate studies indicate that COVID-19 vaccination remains beneficial for adults in reducing cardiovascular risks.

COVID vaccines reduce heart risks by 24%, study confirms despite anti-vax decline
confidence 92%A large-scale study of over a million veterans shows COVID-19 vaccination cuts all-cause cardiac events by nearly 24%, reinforcing protection against heart attacks and cardiac death. While benefits persist, vaccine uptake has fallen due to persistent anti-vaccine messaging. The FDA has also strengthened warnings about rare heart risks tied to mRNA vaccines. No new safety concerns have emerged to outweigh the cardiac benefits.
What's confirmed:
- COVID-19 vaccination reduced all-cause cardiac events by nearly 24% in a study of over one million veterans, covering risks like heart attack and cardiac death.
- The benefits of COVID vaccines extend beyond respiratory protection, including significant reductions in heart-related complications.
- Anti-vaccine rhetoric has contributed to declining vaccination rates despite ongoing cardiac risk reductions from the shots.
- The FDA has required Pfizer and Moderna to add stronger warnings about rare cardiotoxicity risks to their vaccine labels.
Still unconfirmed:
- A single study from Massachusetts suggests a slight link between maternal COVID-19 infection during pregnancy and neurodevelopmental diagnoses in children by age 3, but this is not related to vaccines.
- Robert F. Kennedy Jr.’s opposition to vaccines has intensified public debate, though no new evidence challenges vaccine safety or efficacy.
