Is it necessary to give children the chickenpox vaccine?

Varicella is a relatively common infectious disease that occurs mostly in children. We all know that the varicella vaccine can prevent chickenpox. But does it really work? Is it necessary to give children the chickenpox vaccine? I believe this is a question in many people’s minds. Today, let’s take a look at what the experts say.

Varicella vaccine can stimulate the body to produce immunity against the varicella virus and is used to prevent chickenpox. The pathogen of chickenpox, varicella-zoster virus, is highly contagious. Humans are the only host and the disease is extremely easy to spread. There is currently no effective drug treatment. Vaccination with chickenpox vaccine is the only effective means of preventing the disease, especially in controlling the outbreak of chickenpox.

The immunity provided by the varicella vaccine lasts longer. A survey in the United States showed that 93% of children and 94% of adults had VZV antibodies five years after immunization, and 87% of children and 94% of adults had cell-mediated immunity. A recent report on vaccination by Ampofo et al. showed that the incidence and severity of breakthrough varicella did not increase during the 21 years since 1979, suggesting that there is no significant waning of immunity after vaccination in adults.

Six weeks after vaccination, the seroconversion rate was greater than 98%. For people over 13 years old, the seroconversion rate can reach 100% after two doses (with an interval of 6 to 10 weeks). Protection against varicella is conferred through immunity within 72 hours of exposure to natural varicella infection.
