Cardiologists share vaccine recommendations for heart patients: Flu, COVID-19 and more

August 6, 2026 - 23:17

The American College of Cardiology has released updated guidance stressing that vaccination is a critical part of care for anyone living with cardiovascular disease. The new recommendations cover not just flu and COVID-19 shots, but also several other vaccines that heart patients often overlook.

According to the cardiology group, people with heart conditions face a significantly higher risk of severe complications from respiratory infections. The flu, for example, can trigger inflammation that may lead to heart attack or stroke, especially in older adults with existing plaque buildup in their arteries. Similarly, COVID-19 has been shown to directly damage the heart muscle and increase the likelihood of blood clots.

The updated guidance strongly advises that all heart patients receive an annual influenza vaccine, a current COVID-19 booster, and a one-time pneumococcal vaccine series. The pneumococcal shot protects against pneumonia, which can be especially dangerous for those with weakened hearts. The ACC also recommends the Tdap vaccine to guard against tetanus, diphtheria, and whooping cough, as well as the shingles vaccine for patients aged 50 and older.

Doctors note that some patients worry about vaccine side effects or interactions with heart medications. However, the ACC clarifies that serious adverse reactions are extremely rare, and the benefits of preventing infection far outweigh the risks. They also remind patients that vaccination timing matters. For example, getting a flu shot in early fall provides protection before peak flu season, and COVID-19 boosters can be given at the same time as other vaccines.

The key takeaway from the new guidance is simple: heart patients should not skip their shots. Cardiologists emphasize that staying up to date on vaccines is one of the most effective, low-cost ways to prevent hospitalizations and protect long-term heart health. Patients are encouraged to talk with their care team about which vaccines are right for them and to keep a record of their immunization history.
