Data source: VAERS (Vaccine Adverse Event Reporting System)

Data through 2026 · Updated quarterly

Built by TheDataProject.ai · © 2026 VaccineWatch

Important: VAERS accepts reports of adverse events following vaccination. For any given report, there is no certainty that the reported event was caused by the vaccine. Reports may contain information that is incomplete, inaccurate, coincidental, or unverifiable. Most reports to VAERS are voluntary, which means they are subject to biases. This data cannot be used to determine if vaccines cause or contribute to adverse events.

⚠️

Important: VAERS reports alone cannot determine if a vaccine caused an adverse event. Reports may contain incomplete, inaccurate, or unverified information. Correlation does not equal causation.

Pneumonia Vaccine Side Effects

Pneumococcal vaccines protect against pneumonia, meningitis, and bloodstream infections. Given primarily to young children and adults 65+, these vaccines have extensive VAERS data spanning multiple formulations.

Types of Pneumonia Vaccines

  • Pneumovax 23 (PPV/PPSV23): Polysaccharide vaccine covering 23 serotypes — for adults 65+ and high-risk groups
  • Prevnar 13 (PCV13): Conjugate vaccine covering 13 serotypes — for children and some adults
  • Prevnar 20 (PCV20): Newer conjugate vaccine covering 20 serotypes — replacing PCV13+PPSV23 combo
  • Prevnar 21 (PCV21): Latest formulation with 21 serotypes

Expected Side Effects

Common:

  • Injection site pain, redness, and swelling (very common)
  • Fatigue and muscle aches
  • Headache
  • Low-grade fever
  • Joint pain (more common with Pneumovax 23)

Side effects are generally mild and resolve within 1-3 days. The conjugate vaccines (Prevnar series) tend to cause slightly more injection site reactions than Pneumovax.

Context for Death Reports

Pneumonia vaccines are primarily given to elderly adults (65+) and people with chronic health conditions. This population has a naturally higher mortality rate, so many death reports in VAERS reflect the background death rate of the recipient population rather than vaccine-related events.

⚠️ Remember: VAERS reports show correlation, not causation. Death reports in elderly vaccine recipients largely reflect background mortality rates.
