Vaccines and Immunization

Vaccines Against Infectious Diseases

Children aged younger than 5 years. Much of the burden of infectious diseases could be alleviated if appropriate mechanisms could be put in place to ensure access for all children to basic vaccines, regardless of geographical location or economic status. In addition, new safe and effective vaccines should be developed for a variety of infections against which no effective preventive intervention measure is either available or practical. The public, private, and philanthropic sectors need to join forces to ensure that these new or improved vaccines are fully developed and become accessible to the populations in need as quickly as possible Vaccines against infectious diseases are powerful tools for preventing illness, reducing transmission, and saving lives. These vaccines stimulate the immune system to recognize and mount a defense against specific pathogens, such as bacteria or viruses, thereby preventing infection or reducing its severity. Over the years, vaccines have played a crucial role in controlling and eradicating many infectious diseases, leading to significant improvements in public health worldwide.
