Vaccines contain weakened or inactive copies of diseases. When injected, they stimulate the immune system to develop immunity against those diseases, protecting individuals from future infections. Vaccines have greatly reduced the prevalence of once life-threatening diseases and contribute to the overall immunity of populations, benefiting both individuals and society as a whole.
