For the 2003-04 school year, all states except one submitted reports
of vaccination coverage levels for children entering kindergarten. Fifty reports
included coverage for poliovirus vaccine, diphtheria and tetanus toxoids and
pertussis vaccine, diphtheria and tetanus toxoids and acellular pertussis
vaccine, or diphtheria and tetanus toxoids (DTP/DTaP/DT), measles vaccine,
and rubella vaccines; 49 reports included coverage for mumps vaccine. Coverage
for HepB vaccine was included in 43 reports, and coverage for varicella vaccine
was included in 33 state reports. DC reported on all of the vaccination coverages.
When determining coverage, up-to-date (UTD) status was used rather than number
of doses because the doses required to be UTD vary depending on timing of
vaccinations, area requirements regarding number of doses, and brand of vaccines.
