The Role of Vaccines

Vaccines are the primary tool used for immunization. They contain a small, harmless piece of a pathogen, such as a virus or bacteria, or a weakened form of the pathogen, which stimulates the immune system to produce antibodies and immune cells that can recognize and fight the disease. Vaccines can be administered through various routes, including injection, oral, and nasal. The WHO recommends a range of vaccines for different age groups, from infancy to adulthood, to protect against diseases such as measles, polio, and influenza.

Biologicals: The Building Blocks of Vaccines

Biologicals refer to the raw materials used to produce vaccines, such as viruses, bacteria, and toxins. The WHO works closely with manufacturers to ensure that biologicals are produced to the highest standards of quality and safety. The organization also provides guidance on the use of biologicals in vaccine development and production, ensuring that vaccines are effective and safe for use in humans.
