What Are the Most Common Reactions to a Pneumonia Shot?

The most common reactions to the pneumonia vaccine include mild swelling, redness and soreness at the injection site for a few days, states WebMD. Rarely, the vaccine may cause fever, muscle aches, a severe reaction at the injection site or a severe allergic reaction to an ingredient in the vaccine.

Patients who have a severe allergic reaction to the pneumonia vaccine usually begin experiencing symptoms within several minutes of receiving the shot, explains WebMD. Symptoms may include changes in behavior, problems breathing, dizziness, hoarseness and hives. Pale skin, rapid pulse, weakness and high fever may also result. Patients experiencing any of these symptoms following a pneumonia vaccine should seek immediate medical attention.

A pneumonia vaccine, also called a pneumococcal vaccine, protects people from serious infections that are caused by Streptococcus pneumoniae bacteria, including meningitis, pneumonia and septicemia, states WebMD.

There are two different types of pneumococcal vaccines: Pneumovax and Prevnar 13, notes WebMD. Prevnar 13 is a routine vaccine for infants and toddlers, but it is also approved for use in adults 19 years of age and older with certain medical conditions. Pneumovax is recommended for adults 19 to 64 years old who are cigarette smokers or have certain medical conditions. Both Prevnar 13 and Pneumovax are recommended for all adults 65 years of age or older.
