The varicella vaccine consists of two doses, the first of which can be given after the age of one year, and the second after the age of four weeks. Chickenpox is a contagious disease, and varicella vaccination is the most effective way to prevent chickenpox by causing the body to produce protective antibodies against the varicella zoster virus. For children between the ages of 1 and 12 years, the 1st dose is recommended between 12 months and 18 months of age, with the 2nd dose completed after four weeks of age. If adolescents or adults over the age of 13 have not been previously vaccinated with this vaccine, the interval between the two doses is shortened to 6 to 10 weeks. All in all, the chickenpox vaccine requires a total of two injections, which can be given voluntarily and at your own expense, depending on your child’s or your own needs.
