According to WebMD, side effects of the pneumonia vaccine in infants and children include inflammation and swelling at the injection site, irritability, fever and appetite loss. Side effects of the pneumonia vaccine in adults include muscle aches, fever and pain at the injection site.
Mayo Clinic explains that additional side effects of the pneumonia shot can include muscle stiffness, muscle cramps and movement difficulty. Less common reactions can include headache, nasal stuffiness, sore throat, cough and swollen glands. Not all side effects following a pneumonia injection require medical attention, and certain reactions may dissipate as the body adjusts to the medication. However, individuals should consult with a medical professional if they experience any side effects that cause concern, are unknown, are too uncomfortable or do not subside.
The Centers for Disease Control explains that the pneumococcal conjugate vaccine protects children and adults from 13 different strains of pneumococcal bacteria. The pneumococcal polysaccharide vaccine protects individuals against 23 different types of pneumococcal bacteria and is recommended for senior citizens ages 65 or older, adult smokers between the ages of 19 and 64, and individuals 2 years of age or older who are at a higher risk of contracting the disease. The CDC also states annual flu vaccinations are important because influenza can increase the risk of developing pneumococcal disease.
