Vaccine injuries are a type of adverse reaction to receiving a vaccine. These reactions can range from mild to severe and can be categorized into three types: local reactions, systemic reactions, and allergic reactions.
Local reactions are reactions that occur in the area of the body where the vaccine was administered. These reactions can include redness, swelling, pain, itching, and tenderness in the area. These reactions are usually mild and resolve on their own within a few days.
Systemic reactions involve the body’s systems, such as the immune system, digestive system, and nervous system, and can range from mild to severe. These reactions can include fever, nausea, vomiting, fatigue, muscle aches, and joint pain.
Allergic reactions occur when the body has an abnormal immune response to the vaccine. These reactions can include hives, rash, difficulty breathing, and anaphylaxis, which is a severe and potentially life-threatening allergic reaction.
In some cases, more severe and long-term reactions can occur. These types of reactions are known as adverse events and can include autoimmune diseases, Guillain-Barré Syndrome, and chronic fatigue syndrome.
It is important to be aware of the signs and symptoms of vaccine reactions and to seek medical attention if a reaction is suspected. Vaccines are generally safe, however, reactions can occur.
