As the flu season continues, a pediatrician shares what she wants all parents to understand about the virus this season.

The flu vaccine, which is attenuated, prevents children from two strains of flu A and one or two strains of flu B, depending on the vaccine. It is the easiest way to protect against the flu.

Flu season lasts for months. Right now, most people are experiencing flu A of the N1H1 strain. But Patel suspects that in the spring there will be another surge and this time people will get flu B, which tends to be more severe. Getting vaccinated mid-flu season can protect you from becoming sick later in the season. “It’s never too late,” she said. “Sometimes you see flu until May.”
