 I'm getting vaccinated with Prevnar 20, a Pfizer vaccine. So am I, because I'm at risk for pneumococcal pneumonia. If you're 19 or older with chronic conditions like asthma, diabetes, COPD, or heart disease, or are 65 or older, you are at increased risk for pneumococcal pneumonia. Ask your doctor or pharmacist about Prevnar 20, pneumococcal 20-valent conjugate vaccine.
