Actually, Joe Biden, as President, can nominate somebody to be the Vice President, yet it is easier said than done since there is less than five months remaining in Biden's term. The last time there was a vacancy in the Vice Presidency was when Gerald Ford became President when Richard Nixon resigned. He nominated Nelson Rockerfeller to the Vice Presidency and both houses approved of the nomination therefore we had a Rockerfeller as Vice President.
Let's say that President Nixon didn't have a Vice President in place when he resigned. The new President would have been House Speaker Carl Albert. If something were to happen to Joe Biden and Kamala isn't the Vice President, Speaker Mike Johnson would become the new President.
