Rotavirus vaccine (RVV) coverage for children remains lower than that for the diphtheria-tetanus-acellular pertussis (DTaP) vaccine, a recent study found. Therefore, timely DTaP administration may help improve RVV coverage. Researchers compared coverage and timing of each vaccine series and analyzed characteristics associated with RVV initiation and completion. 10,603 children were enrolled in the study. They found:
- In 2015, ≥1 dose coverage was 91% for RVV and 97% for DTaP.
- 7% of children received their first DTaP vaccine at age ≥15 weeks vs 4% for RVV.
- Recent birth years (2013–2016) were associated with higher odds of RVV initiation (OR=5.72), whereas preterm birth (OR=0.32), older age at DTaP initiation (OR=0.85), income between $50,000 and $100,000 (OR=0.56), and higher maternal education (OR=0.52) were associated with lower odds.
- Once RVV was initiated, recent birth years (2013–2016; OR=1.57) and higher maternal education (OR=1.31) were associated with higher odds of RVV completion, whereas preterm birth (OR=0.76), African American race (OR=0.82), and public or no insurance (OR=0.75) were associated with lower odds.
