On Sunday morning, Health Secretary Matt Hancock said he was in regular contact with his counterpart in Israel, and with good reason.
More than a quarter of Israelis have already been given their first vaccine dose.
As the world-leader in the vaccine rollout, experts across the globe are watching the impact on the outbreak there closely.
Israel says it will share every lesson it learns – but it will not share the jabs with the Palestinians, who say the occupying Israelis have a legal duty to help.
Israel rejects this charge.
Now that the most at-risk groups have been vaccinated, there are growing arguments over who should get the jabs next, as John Ray reports.
