Pneumonia Vaccine: 10 Facts Everyone Should Know

Effectiveness

Pneumonia vaccines are very effective in protecting against pneumococcal infections, which can result in meningitis, pneumonia, and infections in the bloodstream. It is important to note that these vaccines do not offer protection against all types of pneumonia.

The pneumonia shot does not stop you from getting pneumonia. However, it helps reduce cases of invasive pneumococcal diseases.

Studies show that at least one dose of PCV13 protects:

  • Approximately 8 in 10 babies from invasive pneumococcal disease
  • One dose of PPSV23 helps protect about 50–85 out of 100 healthy adults against invasive pneumococcal disease.
  • 45 in 100 adults 65 years or older against pneumococcal pneumonia
  • 75 in 100 adults 65 years or older against invasive pneumococcal disease
