Answer
# Brief Explanations:
The poor and immigrant populations often have higher - need health care situations. Their presence has led to an increased demand for medical services, which in turn has contributed to the growth in the number of vaccines and the need for more hospitals to serve them. Medical transport popularity is not directly related to this population impact. Formation of government agencies is a response but not the most direct impact on health - care improvements. Awareness of germs and bacteria is a general medical discovery not specifically tied to this population's impact on improvements.
# Answer:
The number of vaccines and the need for hospitals grew.
