The flu vaccine is the best prevention against the flu, which can cause serious health problems.

Who is Most at Risk for Flu?

Those most at risk for complications and serious illness from flu include:

Paul Edward Sax, MD, an infectious disease doctor at Brigham and Women’s Hospital, urges pregnant women to get the vaccine, for themselves and their unborn babies. “As an infectious disease doctor, I’ve seen pregnant women who are terribly sick with flu, and it’s such a difficult situation because they’re obviously trying to care for themselves and their unborn child,” Dr. Sax says. “Pregnant women really need to get the flu vaccine.”

Over Age 65? Opt for the High Dose

There are now a number of types of flu vaccines. Dr. Sax strongly recommends that people over 65 receive the “high-dose” shot that has been available in recent years. “The data are growing stronger that the high-dose vaccine is actually a better vaccine for older patients — that they get higher protective levels of antibodies and it correlates with reduced clinical events,” he says. “That’s what I do in my practice.”

Be Prepared Before Flu Starts Spreading

The CDC recommends yearly flu vaccines for people 6 months and older. Vaccination by the end of October is encouraged. But if you miss that date, it is still useful to be vaccinated later in the flu season.
