Pneumonia is an infection of one or both lungs that can cause fever, chills, cough with phlegm, and difficulty breathing. It can range from mild to potentially life threatening depending on individual factors. There are two pneumonia vaccines currently available that will significantly reduce your risk of getting this dangerous infection. Typically, one is given, then at least one year later, a second vaccine is given. This schedule can vary depending on individual factors, so be sure to ask your pharmacist to get your personalized recommendation!
