WASHINGTON Children who attend licensed day care
centers that require
immunizations appear to be more up to date than
children who do not attend a day care facility.
Ayaan Gedi, MPH,City Research Scientist/Unit
Chief, New York City Department of Health and Mental Hygiene, and colleagues
from New York City identified licensed day care centers in the target areas
registered with the New York City Department of Health and Mental Hygiene
Bureau of Immunization (DOHMH). Centers with children enrolled at the time of
assessment were included in the study. Records for all children aged younger
than 6 years were assessed.
The investigators reviewed records for four doses of
diphtheria-tetanus toxoids and acellular pertussis vaccine (DTaP) at 2 years of
age among children aged at least 2 years and for the 4:3:1:3:3:1 series for
children aged 19 to 35 months. The recommended immunization schedule for
children aged 19 to 35 months includes four-dose DTaP, three doses of polio,
one dose of measles- mumps-rubella, three doses of Haemophilus
influenzae type b, and three doses of hepatitis B vaccine. This is referred
to as the 4:3:1:3:3.
Rates of the children attending day care were then
compared with the citywide rates for the 2009 National Immunization Survey.
Of the 7,751 records reviewed at 216 day care centers,
80% of children were up-to-date at the time of the of assessment. Four-dose
DTaP coverage for children aged 2 years was 76%, and 75.5% of children aged 19
to 35 months were up to date for the 4:3:1:3:3:1 series. The median age of the
children was 3.5 years (range, 1-71 months).
In 2008, the New York City DOHMH identified 10 target
areas with the lowest four-dose DTaP coverage among children aged 2 years.
Four-dose DTaP coverage in 2008 in those targeted areas was 71% compared with
the citywide average of 74%. The city average for the 4:3:1:3:3:1 series,
according to the 2009 National Immunization Survey, was 71.7 ± 6.9.
