Odds that Israel will be open to foreigners? Will they have to be fully vaccinated?
IMHO 75% chance open for vaccinated foreigners and 25% open for all
Has anyone seen any indication that they will accept vaccines given in another country?
Yes, the media reported Israel is working out a scheme. It was promised to Greece in reciprocation for Greece accepting Israelis, and a similar deal is being ironed out with the UAE. The main holdup appears to be a debate in Israel whether to accept Chinese & Russian vaccines.
