  1. The flu shot helps prevent against the flu. The flu shot is a vaccine that helps prevent against certain strains of the Influenza virus – the virus that causes flu. It takes two weeks after receiving the shot for the body to build up immunity, and it is important to get vaccinated each year because every year there are different strains of the flu that the shot protects against.
  2. Young children with hypoplastic left heart syndrome (HLHS) may face complications due to the flu. While healthy children and adults may only have cold-like symptoms, individuals with other healthcare concerns may need escalated medical support. HLHS patients who get influenza can become critically ill.
  3. If people around patients with HLHS are vaccinated against the flu, they act as a barrier and protect the patients from getting the flu.This concept is known as herd immunity which protects people with compromised immune systems when the majority of the population is able to shield them from the virus.

Sometimes it is not possible for some individuals to get the flu shot. It’s essential to always discuss your specific situation with your care team but generally, the flu shot is recommended for everyone over the age of six months.
