Pneumonia shot side effects

Updated April 17, 2017

The pneumonia vaccine is an important shot to get, particularly for the elderly and people with a weak immune system, as pneumonia is a common and dangerous disease. Side effects of the pneumonia vaccine are common, affecting about half of all patients, but they are generally mild and subside within a few days.

Composition of the Pneumonia Vaccine

Many people fear that the pneumonia vaccine will cause them to get pneumonia. This is not possible because the vaccine is not made from the bacteria that causes pneumonia. The vaccine is composed of a small part of the bacteria that cannot infect you.

Mild Side Effects

Mild side effects include swelling, soreness and redness at the spot of the injection as well as a low-grade fever, loss of appetite and fatigue.

Severe Side Effects

Severe side effects are rare. A high fever is occasionally reported, and some patients report extreme muscle pain or swelling in the arm.

Allergic Reaction

People who are allergic to latex occasionally have an allergic reaction to the pneumonia shot. Indications of an allergic reaction include trouble breathing, dizziness, racing heart, skin inflammation, swelling of the tongue or throat, and severe fatigue.

Treatment for Side Effects

Treatment for side effects isn't usually necessary, and most side effects subside within a few days. If side effects are severe or if the patient experiences any difficulty breathing, a doctor should be seen immediately. Any side effect that lasts longer than five days should be reported to a doctor, as this could be an indicator of another illness or developing condition.
