Had hit chickenpox vaccine to still be able to give chickenpox

Chickenpox still occurs after vaccination. The protection rate of chickenpox vaccine is about 83%. If two doses of chickenpox vaccine are vaccinated, the protection rate can be increased to 95%, and 100% prevention cannot be achieved. If the child has chickenpox, isolation treatment should be carried out. Acyclovir antiviral treatment should be applied early to shorten the course.
