And then you have plumbing and electricity.
"A virus can affect all of those aspects of your house," he said."
"That makes being vaccinated against COVID-19, flu and other illnesses an important way for people with heart disease to protect themselves."
"That fact can get lost in the swirl of new information, not to mention misinformation, surrounding vaccines.
Now that the updated COVID-19 vaccine is available – and can be given at the same time as the flu shot – here are more straightforward answers from the experts on what people with cardiovascular issues should know about viruses and vaccines."
"Viruses pose serious heart risks"
"Heart issues and infection are linked in many ways.

"Diseases caused by viruses, such as the coronavirus, influenza and respiratory syncytial virus, or RSV, can cause inflammation.
