One of the most common and contagious viral infections is chickenpox, which is caused by the varicella-zoster virus (VZV). It manifests as a rash with itching and fever and can have serious complications, especially for adults, pregnant women, and people with low immunity. The most effective way to prevent chickenpox and its complications is to get vaccinated. The chickenpox vaccine is a safe and effective vaccine that protects against VZV. The vaccine is recommended for all children, adolescents, and adults who have not had chickenpox or received the vaccine before. The vaccine is given in two doses, usually at 12 to 15 months and 4 to 6 years of age for children, and at least 28 days apart for people 13 years and older. The vaccine reduces the risk of getting chickenpox by about 90%, and also reduces the severity and duration of the disease if it occurs. Chickenpox vaccination is important for public health, as it reduces the transmission of VZV and protects vulnerable groups from exposure
In Case of Exposure to an infected person, several recommendations are available. This post is about Post Exposure Varicella Vaccination:
The Advisory Committee on Immunization Practices (ACIP) recommends that people who do not have evidence of immunity and are eligible for vaccination should be vaccinated. Vaccination ideally should be received 3 to 5 days after exposure. The committee also recommends vaccination even after 5 days. This will provide protection for future exposure.
