Final answer:
Measles, mumps, whooping cough, polio, and rubella are all diseases that can lead to severe complications in children and are preventable through vaccinations. While some diseases have been nearly eradicated by vaccines, a decline in vaccination rates has led to a resurgence of some illnesses.
Step-by-step explanation:
Measles, mumps, whooping cough, polio, and rubella are all common illnesses that can lead to severe complications in children. These diseases are preventable through vaccinations, and while some illnesses like smallpox have been eradicated thanks to vaccination efforts, others like polio have been nearly eradicated. However, diseases such as measles and whooping cough, which had been rare due to widespread vaccinations, are now on the rise in some areas, particularly where vaccination rates have declined.
The importance of vaccinations is significant as they help the body to develop immunity against diseases like measles, mumps, and rubella, thereby reducing the prevalence of these infections. The resurgence of certain diseases highlights the ongoing need for immunization among children to prevent the spread and potential complications of these diseases.
