Where can I find more information on side effects?ĭuring the immunization visit, your health care provider will review with you the common reactions to each vaccine and will advise that you seek medical attention if you or your child experiences a serious or unexpected reaction. The vaccine is still safer than the risk of disease. For instance, the risk of GBS after influenza infection is about 17 times higher than it is after influenza vaccination. Most of these events occur following infections with viruses or bacteria, and not following vaccines. These events may occur in about one in a million people who receive the vaccine. ![]() Rare events, such as Guillain-Barre syndrome (GBS), a form of paralysis that usually resolves, are thought to be associated with some vaccines such as influenza and perhaps with tetanus. For example, if you get hives (an allergic reaction) right after a vaccination, it's more likely to be caused by the vaccine than if you get them the next day. It is often hard to tell if a reaction was caused by the vaccine, or if it was caused by something else.

Febrile seizures which happen more commonly in infants and young children, look serious, but almost never are, and children recover with no lasting effects. Sometimes a high fever (which can be caused by many common childhood infections) can cause a seizure, called a febrile seizure. Some people might have a more serious reaction to a vaccine, like a high fever. Some side effects are from the process of immunization, such as those related to fear of getting a needle (for example, anxiety with hyperventilation or fainting). These side effects usually only last a day or two. For those that do, the side effects are usually very minor, like soreness, redness, or swelling where the vaccine was given, or a mild fever.

Of the survivors hundreds of thousands haven't fully recovered, with many suffering from prolonged symptoms for months on end. Keep in mind that COVID-19 is responsible for the deaths of 1.54 million people globally. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases, has said "prolonged side effects" from vaccines like this are "very rare," mentioning "side effects that occur" can include "immediate pain in the arm and the fever." 6254a4d1642c605c54bf1cab17d50f1e But some people have more severe than others."ĭr. "The numbers I've seen range from maybe 2% to 10% - maybe up to 15% - of people having these kinds of really noticeable side effects. "The type of side effects we're seeing with the Pfizer and Moderna vaccines are typical of any vaccine, though there is a spectrum," Moss explained. ![]()
