When JFK was shot, LBJ assumed the presidency. At that time there was no method of replacing a VP.
That situation, among others, is largely responsible for the 25A.
Johnson completed Kennedy's term with no VP.
When he ran in 64 he selected Humphrey as his running mate and HHH remained his VP for the term.

Thank you, so If Joe died suddenly, Kamala would be sworn in and be able to help? select a VP candidate that would become her actual VP with the cooperation of a friendly US Senate?
