Why is it important to have all your childhood vaccinations even though the possibility of getting one of those diseases is not great?

Herd Immunity and personal health

Explanation:

Because many of these deadly diseases have been eradicated years ago but they are coming back. If one person in a group of 100 has not been vaccinated that one person is putting others lives in danger.

An example of personal health would be that of mosquito spray. If a group of 99 people all had mosquito spray on(just like the group of vaccinated kids) and one person had no mosquito spray, all of the mosquito would bite the one person without the repellent.

for respect usually. some people might be little awkward if you meet or some would be different. usually   you dont love people when you meet them depends on the type of person.

hope this

obviously, the latter.
