Schedule considerations for specific groups

Some groups of people have special needs that should be considered in regard to vaccinations. In some cases our jobs may require extra protection, such as healthcare and childcare workers. In some situations, such as when traveling or when immune-compromised, pregnant or breastfeeding, vaccine questions may arise. And, in addition, some children have special vaccine needs, such as adoptees and pre-term infants.
