Vaccines stand among the greatest achievements in public health, yet myths and misinformation persist. Separating fact from fiction helps communities stay protected against preventable diseases.

Common Myths

• “Vaccines cause the disease they prevent.”
  Fact: Vaccines contain inactivated or weakened pathogens that cannot cause full-blown illness.
• “Natural immunity is better than vaccine immunity.”
  Fact: Natural infection can lead to severe complications; vaccines safely train the immune system.
• “Vaccines overload a child’s immune system.”
  Fact: Children encounter thousands of antigens daily; vaccines represent a tiny fraction.

How Vaccines Work
Vaccines introduce an antigen that sparks an immune response—creating memory cells ready to fight the real pathogen in the future. Herd immunity protects those who cannot be vaccinated.

Safety & Monitoring
All vaccines undergo rigorous clinical trials and continuous post-marketing surveillance. Adverse events are rare and closely investigated by regulatory bodies.

Takeaway: Vaccination is a safe, effective way to protect yourself and your community—stay up to date with recommended immunizations.
