i already got a pneumonia vaccine, but i'm asking about the added protection of prevnar 20®. if you're 19 or older with certain chronic conditions like asthma, diabetes, copd, or heart disease, or are 65 or older, you are at increased risk for pneumococcal pneumonia. prevnar 20® is approved in adults to help prevent infections from 20 strains of the bacteria that cause pneumococcal pneumonia. in just one dose. don't get prevnar 20® if you've had a severe allergic reaction to the vaccine or its ingredients. adults with weakened immune systems may have a lower response to the vaccine. the most common side effects were pain and swelling at the injection site, muscle pain, fatigue, headache, and joint pain. i want to be able to keep my plans. i don't want to risk ending up in the hospital with pneumococcal pneumonia. that's why i chose prevnar 20®. ask your doctor or pharmacist about the pfizer vaccine for pneumococcal pneumonia. welcome back to "morning joe."
