Chickenpox disease up to the age of eight is associated with a reduction in the risk of asthma by 88%, allergic rhinoconjunctivitis by 84%, atopic dermatitis by 43%, and allergic sensitization by 89%. In cases of chickenpox, IgE, responsible for allergic reactions) remains low for more than 10 years after the disease.
9.1% of children in the US suffer from asthma and 17% have atopic dermatitis.

Children who developed atopic dermatitis despite chickenpox in childhood visit doctors because of dermatitis at 83 The vaccine against chickenpox, despite the fact that it is alive, does not protect against asthma and allergies.
The authors conclude that vaccination against chickenpox contributed, perhaps, to a sharp increase in the incidence of atopic dermatitis.
Research , proving the economic benefits of vaccination against chickenpox and, did not take into account the increase in the incidence of atopic dermatitis. Since the protective effect of chickenpox on dermatitis lasts up to 8-10 years, it may make sense to wait with vaccination before this age, which will increase the economic benefits of vaccination, and at the same time provide collective immunity.
