Oral vaccination

Oral vaccination is a method of immunization where vaccines are given through the mouth, typically in the form of drops or pills. This approach stimulates the immune system to recognize and fight specific diseases without needing injections. It is especially useful for widespread immunization campaigns because it is easy to administer, non-invasive, and can reach populations with limited healthcare access. Oral vaccines have been effectively used against diseases like polio, cholera, and rotavirus. They work by introducing weakened or inactivated parts of a pathogen to safely trigger immunity, helping protect individuals and communities from infectious diseases.
