Additional key concepts from this publication:

Immunization can help protect unimmunized children, adults and the elderly through herd effects.

Key Evidence: While there have been concerns that vaccinating infants against varicella (chicken pox) would shift the disease to older age groups, numerous studies in countries that have introduced the vaccine have shown a decrease in varicella incidence or in hospitalizations in older age groups of 80% or greater. Indirect protection from vaccination has been reported in individuals not eligible for live vaccines and those who may be at higher risk of complications from chicken pox, such as children <1 year of age, pregnant women and immuno-compromised individuals.
