2. Safety and Tolerance Profile
Recent Data
- Large cohort studies (~100,000 participants) suggest a favorable safety profile with rare adverse events.
- Common side effects include mild injection site pain, fatigue, headache.
- Rare adverse events: myocarditis (notably in young males, incidence ~12.6 per million), pericarditis, and anaphylaxis [4].
Ongoing Trials
- Vaccine safety in special populations: pregnant women, immunosuppressed, elderly.
- Long-term safety: extended follow-up studies (>12 months) underway.
