Can you get chickenpox from someone who has shingles if had before?

Yes, it is possible to get chickenpox from someone who has shingles if you have never had chickenpox or have not been vaccinated against it. Shingles is a reactivation of the varicella-zoster virus, which is the same virus that causes chickenpox.

People with shingles can spread the virus to those who have not had chickenpox or have not been vaccinated through direct contact with the fluid from the blisters. If someone who has never had chickenpox or has not been vaccinated comes into contact with the fluid from the shingles blisters, they may develop chickenpox.
