Decline in MMR rates. Spatial (county-wise) distribution of MMR immunization rates in the (a) base case (\(\mathrm{\alpha }=0\)); (b) post-COVID scenarios (\(\mathrm{\alpha }=10, 15, 25\)) when the decline in the immunization is random uniformly distributed over the population; (c) post-COVID scenarios (\(\mathrm{\alpha }=10, 15, 25\)) when the decline in the immunization is random uniformly distributed over the population when it is correlated with the household income (“weighted”); (d) the difference in the two types of distributions by county
