Figure 1. Vaccination coverage of children who turned the milestone ages each month from January to November in 2019 and 2020. VC assessed by 3 months old (Panel A) and 5 months old (Panel B) for the first and second doses of DTaP and rotavirus vaccines scheduled at 2 and 4 months old. *P-value < .05 for the comparison in VC between 2019 and 2020 using a chi-square test.
Figure 2. Vaccination coverage of children who turned the milestone ages each month from January to November in 2019 and 2020. VC assessed by 13 months old (Panel A) for the first dose of the measles-containing vaccine and for the third dose of the pneumococcal vaccine scheduled at 12 months old, and by 19 months old (Panel B) for the DTaP vaccine and the measles-containing vaccine (second doses) scheduled at 18 months old. *P-value < .05 for the comparison in VC between 2019 and 2020 using a chi-square test.
