How many shots of varicella vaccine are needed? Children aged 2 should be vaccinated against varicella

Chickenpox is a contagious skin disease that occurs mainly during the change of seasons, especially in spring and autumn. Moreover, most children will be infected as long as the disease occurs. It is mainly transmitted through direct contact between people, and sometimes through droplets in the air. So in order to prevent the occurrence of chickenpox, the country has developed a chickenpox vaccine. How many shots of the chickenpox vaccine are needed?

The development of varicella vaccine has reduced the incidence of varicella for many people, especially for children. As for the varicella vaccine, how many shots are needed to play a preventive role? Now, let's ask an expert to tell us how many shots of the varicella vaccine are needed.

Varicella vaccine is prepared by passaged strains of varicella virus and is the only means of preventing varicella infection. Getting the varicella vaccine not only prevents chickenpox, but also prevents complications caused by varicella-zoster.

It is recommended that children begin receiving varicella vaccination at age 2. Children aged 1 to 12 years should receive one dose (0.5 ml); children aged 13 years and above, adolescents and adults should receive two doses, with an interval of 6 to 10 weeks. Children and adults should inject subcutaneously in the upper arm and never inject intravenously. The vaccine should be reconstituted with the diluent provided and should be completely dissolved. Inoculation should be carried out after the disinfectant has completely evaporated. For healthy people, the attenuated varicella vaccine can be administered at the same time as other live attenuated vaccines or inactivated vaccines; for immunocompromised patients and other high-risk groups, the attenuated varicella vaccine can be administered at the same time as other inactivated vaccines. However, they must be injected into different parts of the body and cannot be mixed in the syringe. If the varicella attenuated vaccine cannot be administered at the same time as the measles vaccine, the interval between vaccinations should be at least 1 month.

The experts have given us the above answer to the question of how many shots of chickenpox vaccine should be given. Experts also say that vaccination for chickenpox is generally recommended to start at the age of 2. Experts point out that after receiving the chickenpox vaccine, generally there will be no reaction. Some children will experience symptoms such as fever and rash within a week, but this phenomenon will disappear quickly.
