Patel adds that there are no long-term side effects associated with the flu shot. This type of reaction is the most common adverse effect of the flu shot. Site reactions are a local response around the injection site that may include redness, swelling, soreness, discomfort, or pain. Most side effects from the flu shot can occur soon after getting vaccinated and typically resolve within one to two days (and are local), says Ankur Patel, MD, a geriatrician and chief medical officer at Tabula Rasa HealthCare in Moorestown, New Jersey. Flu shot side effectsįlu shot side effects generally fall into two categories: site reactions and systemic reactions. For many, concern over flu shot side effects makes them avoid getting the injection, but is this fear warranted? Let’s take an in-depth look at the potential side effects of the influenza vaccination. Also, getting the flu vaccine reduces the likelihood that you will pass the flu virus on to vulnerable family members or those who are not eligible to receive the vaccine.Įven in those who are otherwise healthy, getting sick with the flu puts you at risk for serious allergic reactions, but these are quite rare. But when the flu vaccine is well-matched to circulating flu viruses, research shows it can reduce the risk of illness by 40%-60%. Maybe you couldn’t find the time, or you felt like you were healthy enough to fight off the flu virus on your own.
Reasons for vaccination hesitancy are numerous. While that’s an increase of about 2% from the previous season, it still means that only half of the country chose to get the flu shot. But, during the 2020-201 flu season, only about 50% of adults in the United States received the flu vaccine and 59% of children. An annual flu shot is the single best way to protect yourself and your family members against influenza viruses, according to the Centers For Disease Control and Prevention (CDC).
