For many children, flu season means an increased risk of ear infections as well. Although ear infections can strike at any time, they do show some seasonal variation. In a large study published in December, researchers looked at more than 270,000 cases of acute ear infections. They found that ear infections increased along with the flu and illnesses caused by two other respiratory viruses (though not the common cold).
So does that mean that vaccinating against the flu might prevent ear infections in children? Some researchers think so.
