Oral Vaccines

Oral vaccines are immunizations given by mouth, rather than by injection. They contain weakened or inactive parts of a virus or bacteria, stimulating the body’s immune system to produce a defense, or antibodies, against future infections. This method is often easier to administer, especially in children, and can enhance immune response in the gut, where many diseases begin. Oral vaccines have been effective in preventing diseases such as polio and rotavirus, contributing significantly to public health by improving access to vaccination programs.
