Side Effects of the Pneumococcal Polysaccharide Vaccine

Although most people have no problems with the pneumococcal polysaccharide vaccine, side effects are possible. In studies, the most commonly reported problems included swelling, pain, redness, and other reactions at the injection site. If you develop any serious side effects, such as hives, weakness, or difficulty breathing, let your healthcare provider know right away.

An Introduction to Side Effects of Pneumococcal Polysaccharide Vaccine

As with all vaccines, side effects are possible with the pneumococcal polysaccharide vaccine (Pneumovax^®). However, not everyone who receives the vaccination will experience problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.

(This article covers many, but not all, of the possible side effects with this vaccine. Your healthcare provider can discuss a more complete list with you.)
