MINNEAPOLIS/ST. PAUL (10/14/2022) — Flu season is here once again. The last two years have been quieter for influenza activity because of mask-wearing, social distancing and other pandemic restrictions related to COVID-19. Many of those measures have been lifted over the last six months, leaving many to wonder how that could impact flu cases this fall and winter. 

University of Minnesota Medical School expert Marc Jenkins, PhD, speaks about the upcoming flu season and why it’s crucial to get the flu shot. 

Marc Jenkins, PhD
"Flu is still a dangerous infection. Although imperfect, vaccines are by far our best defense against the serious illness that this virus can cause. Vaccines stimulate the layers of our immune system — such as T and B cells — to build up a response for when a virus enters our  the bodies. Vaccines are like an insurance policy for future infection.”

“I keep my COVID-19 and flu vaccines up to date and encourage my friends and family members to do the same.”

Marc Jenkins, Professor at the U of M Medical School, Director of the Center for Immunology
