A. Because you must be born in the US to run for president
This answer really depends on what wing of the Republican party.
The broadest answer to this would be that Republicans view liberty as being more important than public health.
As a result, the government should not compel citizens to get vaccines, even if it would be beneficial.
In George Washington's words "A pasionate attachment of one nation for another produces a variety of evils".
With this statement, as well as a many others in his famous Farewell Address, what Washington was mainly trying to warn the American people about is that becoming fanatical of any political party or overly-obsessive about geographical divisions would always set-up injustice. The privilege of any Nation always comes at the expense of others when sympathy grows into an illusion of "an imaginary common interest". Also of much importance, alliances must be chosen wisely as to not end up betraying the interests of our own Nation in order to defend these alliances. When they're formed without good justification, we end up wrongly following blind and passionate attachment instead of reason.
Hope this helps out!
