can you make this better and clear. The aim of this research investigation is to determine the impact of vaccination coverage on the number of measles cases and the spread of diseases controlled by the Australian government’s MMR vaccination program on the incidence rate. To strengthen the validity of this report, the solution to the research question has been reached based on a systematic review of research journals and websites. Based upon the analysis and interpretation of three relevant pieces of evidence of vaccine coverage rate with number of measles cases and herd immunity of vaccines, has been found that the increase in MMR vaccine coverage has a statistically significant effect on the decreasing incidence rate of measles infection.

The purpose of this research is to examine how vaccination coverage impacts the number of measles cases and the spread of diseases controlled by the Australian government's MMR vaccination program. To ensure the credibility of this report, a systematic review of research journals and websites was conducted to find a solution to the research question. After analyzing and interpreting three pieces of evidence related to vaccine coverage rate, number of measles cases, and herd immunity, it was discovered that an increase in MMR vaccine coverage has a significant effect on reducing the incidence rate of measles infection.
