Important Points to Remember about Viral Vector Vaccines

Like all vaccines, COVID-19 viral vector vaccines have been rigorously tested for safety before being authorized for use in the United States.

  • Vaccines of this type have been well-studied in clinical trials, and viral vector vaccines have been used to respond to recent Ebola outbreaks.

The virus used in a viral vector vaccine poses no threat of causing illness in humans because it has been modified or, in some cases, the type of virus cannot cause disease in humans.

Viral vector vaccines: 

  • Do not affect or interact with the recipient's DNA in any way. 
  • Cannot give the recipient COVID-19 disease
