Based on the information presented in Figure 43.24, which of the following statements is FALSE regarding the impact of vaccination campaigns on polio and measles?

  • A: The introduction of the polio vaccine in the U.S. led to a dramatic and sustained decrease in annual deaths from the disease.
  • B: By 2014, a significant number of countries worldwide had successfully eliminated polio, as indicated by the global maps.
  • C: Measles vaccination rates for infants in 2014 were consistently high (90-100%) across all surveyed regions globally, indicating uniform coverage.
  • D: Annual deaths from measles in the U.S. saw a significant reduction following the introduction of the measles vaccine, similar to the trend observed for polio.

Explanation

Figure 43.24, specifically the 'Rates of measles vaccination for infants in 2014' map, clearly shows that vaccination rates were not consistently high across all global regions. There are significant areas with rates below 50% and even 'Data not available,' indicating non-uniform and often low coverage in parts of the world. The other statements A, B, D are supported by the graphs and maps in Figure 43.24.
