The best time to get the varicella vaccine is when your baby reaches one year of age after birth. Usually one dose of varicella vaccine is sufficient for children between the ages of 1 and 12 years old.
If the child is older than 12 years old, including adolescents and adults older than 12 years old, two doses of varicella vaccine are required, with an interval of 6 to 10 weeks between doses.
Varicella vaccine is a live attenuated vaccine, and a detailed medical history is needed to clarify whether there is any allergy to varicella vaccine components. It is also necessary to conduct a detailed examination of the child’s body to ensure that the vaccine is administered in good health, so as not to affect the production of antibodies.
After receiving the varicella vaccine, you should stay at the vaccination site for 30 minutes to avoid other adverse reactions. Transient redness, swelling and hard nodules may appear at the vaccination site, which is a normal reaction after chickenpox vaccination and need not be overly worried.
