Syncope or Fainting After Vaccination

Fainting or Vasovagal Syncope After a Vaccine

Vasovagal Syncope, or fainting, is a rare but possible vaccine side-effect.  Fainting is reported after nearly every type of vaccine. About 80% of post-vaccine fainting happens 15 minutes after the injections.  Patients may feel dizzy or light-headed though generally regain consciousness within a few minutes.

If you fainted and suffered serious injuries after getting a vaccination, you may be eligible for compensation from the Federal Vaccine Court. If we accept your case, our law firm represents you at no cost.

Severe Injuries After Fainting from a Vaccine

Sometimes fainting after a vaccination leads to falls that can cause serious injuries.  In very rare cases, fainting-related injuries are even fatal. The CDC conducted a study on post-vaccination fainting and found that “7% of the fainting reports were coded as serious; 12% of these involved head injuries.” Another study of post-vaccination fainting published in the U.S. National Library of Medicine finds that “hospitalization was reported in 9.6% of cases” (Braun et al).

Types of Severe Syncope/Fainting Injuries:

  • Head Injury
  • Skull Fractures
  • Brain Hemorrhage
  • Tooth Loss or Dental Damage
  •  Jaw Fracture
  • Other Severe Injuries Lasting More than 6 Months

Recently, we represented an eleven-year-old girl who suffered dental fractures from a syncope episode (fainting) after the flu shot. She stood up following the shot and fainted, falling and hitting her face and teeth on the floor. She went through hours of grueling dental reconstructive surgery to fix the damage. Her mctlaw vaccine injury lawyers won a $39,000 compensation settlement from the VICP to cover future and past expenses related to her injury, as well as an amount for pain, suffering and emotional distress.

Who is Most Likely to Faint After Getting a Vaccine?

Although anyone is susceptible to fainting after a vaccine, studies have found that some patients are more likely than others to experience post-vaccine syncope.  These include:

  • Adolescents: Adolescents between the ages of 11 and 18 are by far the most likely to faint after getting a vaccine, according to VAERS reports.  One study found that 62% of post-vaccine fainting occurred among adolescents.
  • Females: Some studies have found that females are more likely to faint than men after getting immunizations.  One report analyzed 697 cases of post-vaccine fainting and found that 57.5% of fainting episodes occurred among females (Braun et al).

Three vaccines typically given to teenagers are the most commonly reported to cause fainting:  HPV, MCV4, and TDaP.

  • Gardasil, also known as the HPV Vaccine, protects against human papillomavirus, a common viral infection that causes many kinds of cancer.  It is typically administered to children between 11 and 12 years old.
  • Menactra or Menveo, the MCV4 vaccine, protects against meningococcal disease, a serious illness that causes infections in the brain and spinal cord.  It is also typically given to children between 11 and 12 years old.
  • Daptacel or Infanrix, the TDaP vaccine, is a combination shot that protects against tetanus, diphtheria, and pertussis (whooping cough).  It is typically administered to children between 11 and 12 years of age as well.VA

My experience with mctlaw for my hip claim was remarkable, I found the communication to be outstanding. I also felt they did an excellent job setting expectations and then delivering on those stated expectations. From net amount, timing of the settlement, how much each related party would receive etc. they were outstanding. I would highly recommend them. They are very professional and set the bar in vaccine injury practice.


Five stars for mctlaw! Paralegal Leslie Williams did an outstanding job communicating with us and keeping us informed. Thanks for all the help.


I am excited to be receiving my final payment so I can put all this behind me. I am really grateful to everyone who played a part in getting me this well deserved settlement as my life has been negatively impacted over the years.


We cannot thank you enough for the services your firm has provided for Marie and I in our time of need. I could not have chosen a finer firm near or far to represent us.

My first response is “Wow!” It has only been 11 months since I first heard of “SIRVA” and an HHS program that awarded compensation to its victims and only 7 months since MC&T accepted my case. I feel that your efforts on my part made all the difference.
