Anaphylaxis & Allergic Reactions to Vaccines

Vaccines, like any other medication, can cause Anaphylaxis, also known as an allergic reaction. Our vaccine injury lawyers are skilled at handling cases of adverse reactions to vaccines such as the flu shot, TDaP/DTaP, and others that are covered under the National Vaccine Injury Program. In the past year alone, our firm has obtained over $40 million in vaccine injury settlements since 2019.


What is anaphylaxis?

Anaphylaxis or an anaphylactic reaction is a severe allergic reaction and can be potentially life-threatening. The reaction can occur within seconds or minutes of exposure to a foreign substance. The most common causes of Anaphylaxis are drugs, foods, or insect bites. Recently, Paul Brazil Won Compensation for Woman Who Suffered Injuries from Multiple Vaccines. Symptoms of Anaphylaxis can include:

  • Hives
  • Swelling of the tongue and/or throat
  • Shortness of breath
  • Hoarseness
  • Spasms
  • Abdominal pain
  • Vomiting

How is anaphylaxis treated?

In severe anaphylactic reactions, the universal treatment is epinephrine injection, usually referred to by the brand name EpiPen®. Epinephrine is injectable adrenaline. The injection is performed in the thigh as soon as symptoms begin. The epinephrine works by relaxing and opening airways which makes breathing easier. The adrenaline also relieves itching, hives, and swelling.

Recently, My Vaccine Lawyer's founding partner Paul Brazil was interviewed by Jodie Fleischer of NBC4 Washington about vaccine injuries such as Anaphylaxis and Anaphylactic Shock, along with the National Vaccine Injury Compensation Program which is a federal compensation program for vaccine injuries in the United States. Paul and Jodie also discuss the frequency of these injuries and the lack of public knowledge about the VICP.
