What are the potential side effects of chickenpox vaccine?

Fact Checked

The chickenpox vaccine is formally called as the varicella vaccine which is a type of inflammation given in order to prevent the development of chickenpox among those who are treated with the vaccine. Chickenpox is an infection triggered by the virus known as varicella-zoster and considered as a highly transmissible disease. With the help of the vaccine, it might help prevent the condition from developing or help minimize the severity of the symptoms.


The vaccine is given as an injection among children between 12 and 15 months old and then followed by a booster shot that is given between 4 and 6 years old. Parents must carefully discuss with the doctor the possible symptoms as well as the side effects of the chickenpox vaccine before the child is immunized.
