At first blush, receiving a vaccine can seem like an obvious choice. Rather than potentially getting a dangerous illness, a vaccination is offered that you are told can prevent serious harm.

However, there are times when a vaccine does not work the way that it is supposed to. In some cases, the vaccination can have unintended consequences, creating an injury.

These are some of the symptoms you should watch for after receiving a vaccine.


Allergic reactions to vaccines are rare but can occur in some individuals. The first symptoms of an allergic reaction to a vaccine can include hives, itching, wheezing, difficulty breathing, and a drop in blood pressure. You should seek medical attention immediately if you experience any of these symptoms after being vaccinated.


Anaphylaxis is a severe and potentially life-threatening allergic reaction to a vaccine. Symptoms of anaphylaxis can include rapid heartbeat, difficulty breathing, swelling of the face and tongue, and a drop in blood pressure. If you experience symptoms of anaphylaxis after being vaccinated, you should seek emergency medical attention immediately.


Systemic reactions refer to symptoms that occur throughout the body rather than just at the injection site. These symptoms can include fever, fatigue, muscle aches, and headaches. Some systemic reactions are mild and go away on their own within a few days.  Others can become chronic and lead to more debilitating autoimmune or autoinflammatory type of conditions.


Vaccines can also cause neurological reactions, such as seizures, encephalitis, and Guillain-Barre syndrome, just to name a few. These symptoms can be severe and require immediate medical attention. If you experience any unusual or severe symptoms after being vaccinated, it is vital to seek medical attention right away.

The first symptoms of a vaccine injury can include local reactions, allergic reactions, systemic reactions, neurological reactions, and anaphylaxis. If you experience any unusual or severe symptoms after being vaccinated, it is essential to seek medical attention right away.
