Millions of people get the flu shot to protect themselves against influenza. This vaccine is usually administered as an injection or nasal spray. It reduces your risk of getting influenza by up to 60%, according to the CDC.
There is a misconception that flu vaccines can cause influenza, but this is not true. The flu shot is made from inactive or dead flu viruses, so there is no way that it can lead to an infection. This myth probably exists because a few of the flu shot’s side effects are similar to flu symptoms. For example, some people feel nauseated after getting a flu shot, which is a sign of influenza.
Most side effects caused by the flu shot are mild, and patients of all ages can experience them. Common side effects of the influenza vaccine include the following.
The injected area might be sore, warm, or red for a couple of days after getting the vaccine. In some cases, the soreness is accompanied by inflammation. Patients can treat this side effect by taking painkillers.
Some people report headaches or pain throughout their bodies after getting a flu vaccine. This is more likely to occur the first day after getting the vaccine, and it should be gone within two days. Over-the-counter painkillers can counter any discomfort.
It should be noted that there is controversy regarding taking painkillers that contain ibuprofen or acetaminophen after getting a flu vaccine. One chain of thought suggests that these painkillers might change the body’s response to the vaccine. However, research on the topic remains inconclusive.
Patients might feel dizzy after getting their flu shot. This typically goes away in one or two days. People who feel lightheaded when getting injections should inform the doctor about their condition before getting the flu vaccine. Eating a snack before getting the vaccine and resting for a few minutes can help prevent feeling dizzy.
Some patients report feeling feverish after getting vaccinated for the flu. It is usually a mild fever that goes away in a couple of days. Over-the-counter painkillers can be used to manage it if it causes significant discomfort. In rare cases, the flu shot can lead to a high fever that requires urgent medical care.
Allergic reactions to the vaccine are among the more severe side effects that a patient might find themselves dealing with. These reactions typically occur within a few hours of getting the vaccine. Common allergic reactions to the flu vaccine include:
Patients who notice any of these symptoms should go to a doctor for urgent care right away or head to the emergency room.
