"We recommend getting the flu shot as soon as you can," said Dr. Vivian Torio, a Family Medicine Physician with Kaiser Permanente Fresno.
But it's especially important for people dealing with underlying heart conditions.
Dr. Torio explains that respiratory illnesses can take a toll on the heart.
"It'll cause the heart to beat faster, that can increase your blood pressure," said Dr. Torio. "We're seeing those who are hospitalized with the flu infection and pre-existing cardiovascular disease have a higher risk for heart disease, acute heart failure, heart attacks, pneumonia, bronchitis, and respiratory failure, among other complications."
That's why health experts say getting the flu shot can help prevent future heart problems and complications.
Dr. Torio adds that getting your flu shot is an extra layer of protection to keep you healthy.
"Irregardless of if you get the infection, the vaccine will still help decrease the severity of the symptoms and the longevity of the symptoms," said Dr. Torio.
Last year saw a severe season for the respiratory virus. While cases aren't up yet, doctors say getting your flu shot can help keep more people out of the hospital.
"We see less people getting severe illness is what we call it," said Dr. Torio. "We saw that with those who are vaccinated versus not."
With Halloween and other holidays coming up, doctors say to give your body at least two weeks to adjust to the flu vaccine.
