Vaccinations

About

Vaccinations are a crucial medical intervention that protects individuals against infectious diseases by stimulating the immune system to produce antibodies. This process helps prevent diseases, disabilities, and deaths from vaccine-preventable diseases (VPDs) such as measles, polio, and tetanus. Vaccines contain weakened or killed forms of pathogens, which do not cause the disease but train the immune system to recognize and fight them. Over the years, vaccinations have saved millions of lives and are considered one of the most effective public health strategies. Vaccines protect against more than 20 life-threatening diseases and are essential for global health security. They not only safeguard individuals but also contribute to herd immunity, protecting those who cannot be vaccinated. The World Health Organization and other health bodies continually work to improve vaccination coverage and develop new vaccines against emerging diseases. Vaccination is a safe and effective way to build immunity without exposing individuals to the full force of a disease, making it a cornerstone of preventive medicine.
