PORTLAND, Ore. -- Oregon has new immunization requirements for preschool, kindergarten, and seventh grade this fall.

Health officials said a Hepatitis A vaccine is now required for entrance into preschool and kindergarten.

Tdap, a combination of tetanus, diphtheria and pertussis vaccines, is required for entrance into seventh grade. This vaccine differs from the shots that most children received as a baby.

Parents were urged to check immunization records to determine if their child needs additional vaccinations.

• August 28th,
