Immunization is a vital public health strategy, protecting individuals and communities from infectious diseases through vaccines. This section explores the...
Vaccines introduce a weakened, inactive, or partial version of a pathogen to the body. This safely stimulates the immune system to produce antibodies and memory cells, providing future protection against the actual disease.
Immunization primarily prevents serious infectious diseases, reducing illness, disability, and death. It also contributes to herd immunity, protecting vulnerable populations who cannot be vaccinated.
Yes, vaccines undergo rigorous testing and continuous monitoring for safety and effectiveness before approval and throughout their use. Serious side effects are extremely rare, and their benefits far outweigh potential risks.
Herd immunity, or community immunity, occurs when a significant portion of a population is immune to a disease, making its spread unlikely. This indirectly protects those who are unvaccinated or cannot develop immunity.
