The fee of HZ amongst children who have been unvaccinated climbed from 2003 to 2007 after which declined sharply by way of the tip of the examine interval. Increasing charges of vaccination over the examine interval decreased the danger of contracting HZ total for all children, together with those that have been unvaccinated.
