adverse events following immunization

Adverse events following immunization are health issues that happen after receiving a vaccine. They can range from mild, such as soreness or swelling at the injection site, to more serious, but rare, reactions like allergic responses. It's important to remember that most side effects are temporary and much less serious than the illnesses vaccines prevent. Monitoring these events helps ensure vaccines are safe, and healthcare providers are prepared to address any reactions. Overall, vaccines are safe and an essential tool to protect individual and public health.
