In regard to the modification, it is suggested to change the test variable in order to enhance all pieces of evidence. To refine the research question and experiment, different types of childhood vaccines will be considered, such as pertussis, rubella, and hepatitis B.
By implementing a process of creating reliability through repeated testing trials or changing the test variable of the effect of measles on transmission rate, and a standardised method of data collection that is consistent worldwide, the validity of the outcome will be improved by addressing limitations. As stated above, the quality of the evidence is bind to the dataset used to establish a direct causal relationship.

By implementing a process of creating reliability through repeated testing trials or changing the test variable of the effect of measles on transmission rate, and a standardized method of data collection that is consistent worldwide, the validity of the outcome will be improved by addressing limitations. As stated above, the quality of the evidence is tied to the dataset used to establish a direct causal relationship.

To improve the reliability of the study, implementing a process of creating reliability through repeated testing trials or changing the test variable regarding the effect of measles on transmission rate is necessary. Additionally, using a standardized method of data collection that is consistent worldwide will also contribute to enhancing the validity of the outcome and addressing limitations.

It is important to note that the quality of the evidence is tied to the dataset used to establish a direct causal relationship, as mentioned above.
