Abstract:
|
Routine administration of all age-appropriate doses of vaccines during the same visit is recommended for children by the Advisory Committee on Immunization Practices. It is an important standard for achieving the national targets of 90% vaccination coverage of two year old children for most recommended vaccines. However vaccination coverage for the fourth dose of DTaP (diphtheria and tetanus toxoids and acellular pertussis vaccine), fourth dose of PCV (pneumococcal conjugate vaccine), and full series of Hib (Haemophilus influenzae type b vaccine) have not reached the 90% target. Potentially achievable (PA) vaccination coverage is defined as coverage if missed opportunities for same day administration of childhood vaccines had been eliminated. Using National Immunization Survey data, we assess the PA vaccination coverage of these three vaccines, compare the PA vaccination coverage to the reported vaccination coverage in the United States from 2001 to 2012, and evaluate the PA vaccination coverage by state and selected socio-demographic factors in 2012. Compared to reported coverage, PA vaccination coverage would increase significantly, and reach or be very close to the 90% target.
