Simply tell her even with the vaxx that she can't fly as of now, tell her to wait until flights resume and see if it's compulsory. Show her the Isreal court decision that it's illegal for gov't to stop people from traveling unless vaccinated, hope it sinks in and all the best. Unfortunately my friends in hotel quarantine have buckled and got the Pfizer jab, i lost my shit at them but they have to eat i suppose, all four of them had a fever and sweats for two days and a very sore arm for about 4 days. We won't know of the complications from these jabs for years to come, but finger crossed nothing happens. Good luck sierra i do feel for you.
