Here's how long the flu is actually contagious, according to doctors

Parade, February 10, 2023

Dr. Megan Berman, an internal medicine doctor and associate professor of general medicine at the University of Texas Medical Branch, explains that the flu is primarily spread through respiratory droplets, AKA very small droplets made when someone infected coughs, sneezes or talks. “They find their way to someone’s mouth or nose nearby,” she said, adding that the flu can also be spread through kissing or sharing eating utensils. Dr. Berman also said that vaccines take a couple of weeks to work. “If someone was vaccinated and came down with laboratory-confirmed flu the next day, they were already exposed, and the vaccine did not have enough time to make an immune response for prevention.”
