When is the second shot of varicella vaccine? Is it a problem to make it domestically before importing it?

Only one shot is recommended for varicella vaccine in the first few years, and it can be given after one year old. Later, because some children who have been injected will still be infected with chickenpox, it is recommended to take a second injection at the age of 4-6. The second injection can be done two months after the first injection. As for children making domestic products before importing, there is no problem. Children should receive the first dose of varicella vaccine at 12- 18 months, and the second dose at 4-6 years old. Although most children can be protected by a shot, some children still do not form the expected resistance. Especially in kindergartens, children are still at risk of being infected with varicella virus. & gt
