February is National Heart Health Month: How Vaccines Protect Your Heart

February is National Heart Health Month, a time to raise awareness about cardiovascular health and how to protect our hearts. In the US, heart disease is the leading cause of death among all adults. In 2022, roughly 1 out of every 5 deaths of adults under 65 was from cardiovascular diseases.
While most people associate heart health with diet, exercise, and lifestyle choices, one often-overlooked factor is vaccination. Vaccines play a critical role in protecting your heart and reducing the risk of serious complications from infections.
Heart conditions can weaken the body’s ability to fight off infections. Therefore, they heighten the risk of severe complications from illnesses such as COVID-19, the flu, pneumococcal disease, and respiratory syncytial virus (RSV). These infections can trigger inflammation, increasing the likelihood of blood clots and arterial blockages, which may lead to heart attacks or strokes.
At US Physicians’ Purchasing Group, we understand the importance of immunizations—not only for preventing infectious diseases but also for supporting overall health. Here’s why vaccines should be part of your heart-healthy routine.
1. Lower Risk of Heart Attack and Stroke
Studies have found that getting an annual influenza vaccine can significantly lower the risk of heart attacks and strokes. One study revealed that people who received a flu shot had a 34% lower risk of major cardiovascular events in the year following vaccination. The flu can put extreme stress on the heart, and preventing the virus can help keep your cardiovascular system stable.
Despite being high-risk, a survey from the National Foundation for Infectious Diseases showed a lack of awareness about the importance of annual flu vaccination.

Did you know?
A 2018 study found that the risk of heart attack was 6x higher during the first week following a positive flu test.
2. COVID-19 and Heart Health Protection
The COVID-19 vaccine is another crucial tool in heart health protection. COVID-19 can cause serious cardiovascular complications, including inflammation of the heart muscle (myocarditis) and blood clots, which can lead to strokes. Vaccination reduces the severity of COVID-19 and helps prevent these life-threatening complications.
3. Pneumonia and Shingles Vaccines Help Prevent Cardiac Events
These infections can pose serious threats to the heart. Pneumonia has been linked to an increased risk of heart attacks and strokes, especially in older adults and those with underlying conditions. The pneumococcal vaccine protects against pneumonia, while the shingles vaccine can reduce the risk of inflammation-related heart issues.
4. Vaccination is a Simple and Effective Preventative Measure
Taking steps to maintain heart health doesn’t have to be complicated. In addition to eating a heart-healthy diet, staying active, and managing stress, staying up to date on recommended vaccines is one of the easiest ways to reduce cardiovascular risks. By getting vaccinated, you’re not just protecting yourself from infections—you’re also safeguarding your heart.
Who Should Prioritize Heart-Healthy Vaccinations?
While vaccines benefit everyone, certain groups are at a higher risk of heart-related complications from infections. If you or your patients fall into any of the following categories, staying up to date on vaccinations is especially important:
- Adults aged 65 and older. As the immune system weakens with age, the risk of severe illness and cardiovascular complications from infections like the flu, pneumonia, and RSV increases.
- Individuals with existing heart conditions. Those with conditions such as coronary artery disease, heart failure, or a history of heart attack or stroke are more vulnerable to inflammation-triggered cardiovascular events.
- People with high blood pressure or diabetes. Both conditions already put strain on the heart, and infections can further increase the risk of complications.
- Smokers and individuals with chronic lung conditions. Smoking and lung diseases like COPD can compromise cardiovascular and respiratory health, making vaccinations an essential preventive measure.
- Pregnant women. Pregnancy places additional strain on the heart and immune system. Vaccines, like the flu and Tdap vaccines, help protect both mother and baby from serious infections.
Ensuring these individuals receive recommended vaccinations can help prevent severe illness, reduce hospitalizations, and ultimately save lives. As a healthcare provider, offering guidance on the connection between vaccines and heart health can encourage more patients to take proactive steps toward protection.
