For which age group is the varicella vaccine mainly indicated?

The varicella vaccine, commonly known as the chickenpox vaccine, is primarily indicated for children over the age of 12 months and for susceptible individuals who have not previously had chickenpox or have not been vaccinated. This recommendation is in line with public health guidelines, which emphasize the importance of vaccination during early childhood to ensure adequate immunity against varicella disease.

Vaccinating children at a young age helps protect them from potential complications associated with the infection, such as pneumonia, encephalitis, and secondary bacterial infections, as well as reduces the overall spread of the virus within the community. It's important to note that while older age groups may benefit from vaccination if they are susceptible, the primary target population for the varicella vaccine is indeed young children, particularly those who are at least one year old.
