Can the varicella vaccine cause chickenpox? Can other children or adults get chickenpox from being exposed to a child who has recently received the vaccine?
The varicella vaccine may cause chicken pox since it is a live, weakened virus. About 1% of recipients per year develop a chickenpox rash, which is much milder than the naturally occurring chickenpox, and is usually without fever. The few children who develop a rash after receiving the chickenpox vaccine may be contagious for a short period of time. Should this occur, they will spread the weakened vaccine virus, not the wild virus.
