Israel was mostly closed to foreign nationals from March 2020 until March 2022.
When it reopened, passengers had to take a PCR test and had to wear a mask in-flight. Those requirements were dropped this past May, but Israel still required that you complete a health entry form before flying to Israel.
As of this Sunday, that form is no longer required, and with that, all of Israel’s COVID entry requirements are history.
The US still requires that adult foreign nationals be vaccinated, one of the few countries that still have that rule on the books.
