Yes, the vaccine is safe for people with heart and circulatory conditions. No vaccine will be approved unless it is considered safe for people with long-term conditions, including heart and circulatory conditions, and including older people.

In the case of the Pfizer/BioNTech vaccine, there were no meaningful differences in how well it works in people with health conditions that put them at risk of severe Covid-19 (including diabetes, high blood pressure, asthma and obesity.)

Testing for the Oxford vaccine included people with heart and circulatory disease, diabetes, lung disease and obesity, and found it gave similar levels of protection as to those who did not have those conditions.

Similarly, the testing for the Moderna vaccine included people with diabetes, significant heart or circulatory disease, chronic lung disease, severe obesity and liver disease. The research found that the vaccine worked similarly well in these higher-risk groups to the general population. 

The British Society for Heart Failure's (BSH) states that; "Vaccines allow an individual to develop immunity to a virus and they reduce the risk of infection. If patients are unfortunate enough to catch the infection despite vaccination, then vaccines may reduce the severity of the illness.

Nancy Albert, PhD RN, President of the Heart Failure Society of USA. “We have learned a lot about clinical care and infection control. Being vaccinated is an important step in prevention. We are now well positioned to let patients with heart failure know that both COVID-19 vaccines are safe and effective.”

Cardiomyopathy organization of UK strongly encourages people with cardiomyopathy to accept the COVID-19 vaccination if offered.

Experts have a simple answer for heart and stroke patients questioning whether they should get a COVID-19 vaccination. That answer: Yes.

"People with all kinds of cardiovascular risk factors and disease should definitely get vaccinated to protect themselves and their families from COVID-19," said Dr. Mitchell Elkind, a professor of neurology and epidemiology Columbia University Irving Medical Center in New York City.

The Food and Drug Administration-approved vaccines pose no special problems for such patients, said Elkind, who also is president of the American Heart Association. The AHA issued a statement encouraging people with cardiovascular risk factors, heart disease or a history of heart attack or stroke to get vaccinated "as soon as possible." Getting vaccinated is especially important for them, Elkind said, because people with such underlying conditions have a higher chance of developing complications from COVID-19, the disease caused by the coronavirus.

In general, yes.  As with any injection, there is some risk of bleeding.

Like most vaccines, the coronavirus vaccine is injected into the muscle of your upper arm. Injections into muscle may bleed a little more than injections that are given under the skin, but less than those that are given into a vein.

If someone is taking a blood thinner such as warfarin, or a new anticoagulant, the bleeding may take a little longer to stop and may get more bruising on upper arm.

Public Health England and the Department of Health have said that patient can have the vaccine if their anticoagulant treatment is stable. That generally means that patient taking the same dose for a while and that if they are on warfarin, that their INR checks are up to date and that their latest INR level was in the right range.

Yes, the vaccine is safe for people taking clopidogrel and other antiplatelet medications. People may experience a little more bruising around the injection site.

Yes, the coronavirus vaccine is safe for people taking heart medications. Expert don’t have any reason to think that any heart medication will interact with the coronavirus vaccine itself. Heart medication won’t stop the vaccine from working, and the vaccine won’t cause problems with heart medication.
