Most people think chickenpox is a harmless childhood disease.
But it can cause serious problems in children. And it can be especially bad for pregnant women and other adults who have never had the disease. Chickenpox can be prevented with a new vaccine that was recently approved for use in Canada. A handout for parents and caregivers that looks at exclusion policies, and whether children should attend school or daycare while they have chickenpox. The NACI statement , published in May 1999, includes details about chickenpox in Canada and recommended use of the vaccine.
