Encephalitis Caused by Vaccine

Encephalitis is the inflammation of the brain. It is a serious condition that can be caused by many things, including vaccines. Viral diseases such as herpes simplex virus (HSV) and enteroviruses can cause someone to develop encephalitis. Common childhood infections such as measles have also been linked to it. There are many other viruses that can cause someone to develop encephalitis including those spread by mosquitoes and ticks.  

Autoimmune inflammation, which sometimes occurs as a reaction to a vaccine, can also trigger encephalitis. If you have been diagnosed encephalitis after receiving a vaccine, it is important to speak with an experienced vaccine attorney right away. You may be entitled to compensation.

Encephalitis has flu-like symptoms including fever, headache, aches in muscles or joints, and fatigue. More severe symptoms include confusion and hallucinations, seizures, being unable to control certain areas of the face or body, problems with speech or hearing, and loss of consciousness. 

Young children and the elderly are most likely to be impacted by encephalitis. Young children may experience the previously mentioned symptoms as well as bulging in the soft spots (fontanels) of an infant's skull, nausea, vomiting, body stiffness, and poor feeding.  

If you or a loved one experience any of these severe symptoms it is important that you seek medical attention immediately. 



The earlier encephalitis is diagnosed the better. There are various types of effective treatments that are used depending on the severity of the condition. 

  • Antiviral Drugs: Medications like Acyclovir, Ganciclovir, and Foscarnet are most commonly used to treat encephalitis that has been caused by another virus. 
  • Anti-Inflammatory Druga: Similar to antiviral drugs, anti-inflammatory drugs fight off underlying infections that may have caused encephalitis. 
  • Immunotherapy: Steroids, intravenous antibodies (IVIg), and plasma exchange are used to treat encephalitis when the cause is believed to be autoimmune. 
  • Supportive Care: In more severe cases that require a hospital stay people may need intravenous fluids, anti-inflammatory drugs, breathing or feeding assistance, and other means of health support. 
  • Follow-up Therapy: Some cases require therapy such as physical or speech therapy to help overcome more severe symptoms. 



Encephalitis is considered an adverse reaction that can be compensated under the NVICP according to the Vaccine Injury Table. Encephalitis is a known adverse reaction to many vaccines such as childhood vaccines and seasonal flu vaccines. 

Individuals who have suffered from encephalitis after receiving a covered vaccine can be compensated through the National Vaccine Injury Compensation Program (NVICP). 

The NVICP is a federal program that was created to compensate people who have been injured by certain vaccines. If you or a loved one have been injured by a vaccine, you may be entitled to compensation for your injuries. 

In order to take advantage of the VICP, you must file a petition with the U.S. Court of Federal Claims. There are specific rules that must be followed when submitting a claim. An experienced vaccine attorney can help you navigate the process and help ensure that you receive the compensation you deserve. 



The amount of compensation you can receive is dependent on your situation, the severity of your symptoms, and how long they lasted. With some exceptions, there typically is no set compensation amount for specific vaccine injuries. However, depending on the severity of your vaccine-related injuries and damages, the compensation you receive can be substantial.  

Receiving compensation through the NVICP is complex, which is why it’s important to consult with a vaccine injury lawyer. An experienced vaccine attorney will be able to help you better understand your options. 


Encephalitis is an adverse reaction that can have serious effects on your day-to-day life. You may be entitled to compensation for your injuries through the VICP. Don't wait. There are deadlines to file a claim. The experienced vaccine injury attorneys at the Law Offices of DuPont and Blumenstiel can help. Call us today at 614-389-9711 for a case evaluation.
