Overall, the average vaccination coverages were 95.5% (SD = 1.1; range 93.3–96.8) for pertussis vaccine, 95.6% (SD = 1.1; range 93.4–96.8) for diphtheria vaccine, 95.7% (SD = 1.0; range 93.6–96.8%) for tetanus vaccine, 95.6% (SD = 1.1; range 93.3–96.8%) for polio vaccine, 90.9% (SD = 10.1; range 54.7–96.0%) for Hib vaccine, 87.5% (SD = 5.1; range 74.1–94.4%) for MMR vaccine, and 74.5% (SD = 21.5; range 30.7–90.6%) for varicella vaccine, with some variations from 2000 to 2020. This evidence concerns the gene MRC1 and diphtheria.
