MGWR parameter estimates for the age group variables. The grey colour pertains to statistical non-significance at 95% interval. In comparison with the age 30–39 (the reference age category), the age 18–29 is associated with a lower vaccination rate in several parts of England, implying that young people are less likely to get vaccinated than the 30–39 group. The senior groups (40–49, 50–59, 60–69, 70–79, and 80 over) exhibits a positive association with the vaccination rates, especially in the central and northern England
