Vaccine and Clinical Trials

Adverse reactions to the vaccination

 Before being approved for clinical usage, anti-infection medicines are tested for adverse responses. Depending on the type of antimicrobial used, the organisms being treated, and the patient, certain antitoxins cause mild to severe side effects. Immunizations usually cause less harmful side effects, such as mild fever, migraine, muscle and joint pain, shaking, and so on, but almost no antibodies cause rare symptoms, such as hypersensitivity, or anaphylactic reaction.
