Antivenom injections provide passive immunity by introducing preformed antibodies against specific toxins, such as snake venom, directly into the patient In contrast, polio drops are a vaccine that induces active immunity. Vaccines typically consist of inactivated or weakened (attenuated) pathogens or antigenic proteins When these attenuated pathogens are administered, they stimulate the host's immune system to produce antibodies against the antigen without causing the disease
