Vaccine-associated enhanced disease (VAED) is a rare phenomenon in which a (usually) more severe clinical presentation of an infection that would normally be seen in an unvaccinated person occurs in someone who has been vaccinated. 

MVEC’s reference page on VAED has recently been updated. This resource outlines:  

  • what VAED is  
  • mechanisms for enhanced disease 
  • assessment and evaluation of VAED
