Vaccines and sera serve different purposes in immunology. Vaccines are substances that stimulate the immune system to produce an adaptive immune response, including the formation of antibodies, to protect against specific infections. In contrast, sera contain pre-formed antibodies and are used for passive immunization, providing immediate but temporary protection against diseases. Essentially, vaccines prepare the body for future infections, while sera offer immediate, short-term immunity.
