  Severe allergic reactions to vaccines are rare but can happen. If you get a COVID-19 vaccine and you think you might be having a severe allergic reaction after leaving the vaccination provider site, seek immediate medical care by calling 911.
  
  A severe allergic reaction can cause
  
  • difficulty breathing or wheezing,
  
  • a drop in blood pressure,
  
  • swelling of the tongue or throat, or
  
  • a generalized rash or hives, which may include mucus membranes.
