Jordan's King Abdullah II said Thursday Israel's failure to provide vaccines to Palestinians in the West Bank or the Gaza Strip was counterproductive for the Jewish state.
"The Israelis have had a very successful rollout of the vaccine, however the Palestinians have not," Abdullah told the annual World Economic Forum in Davos, Switzerland.
"You cannot vaccinate one part of your society and not the other and think that you are going to be safe," he said via videoconference. "That is the number one lesson that COVID-19 taught us."
Israel launched its vaccination drive a month ago. Since then nearly 2.8 million of its nine-million population have received a first jab, with half of that number already getting the second dose too.
And although Jewish settlers in the West Bank are being inoculated, Palestinians are not, prompting sharp criticism from human rights groups and the Palestinians themselves.
Earlier this month the Palestine Liberation Organisation urged the international community "to hold Israel to account" and ensure that it provides vaccines to "all Palestinians living under Israeli occupation."
However, under the terms of the Oslo Accords, the Palestinian Authority is responsible for the healthcare of its own population.
Ramallah also did not make an official request from Israel and has repeatedly said it is obtaining its own vaccines via a UN scheme and from Russia for its Sputnik V treatment.
Abdullah said Thursday that the novel coronavirus "does not care about borders, the rich or the poor or whoever."
"We have got to look at the practicalities and the challenges that are ahead of us, to be able to communicate with each other and realize that we are one world, one small village," he said.
Some 2.8 million Palestinians live in the West Bank while two million others live in the Gaza Strip, which is blockaded by Israel and Egypt, citing security concerns.
In mid-January, under pressure from rights groups and Attorney General Avichai Mandelblit, the Israel Prison Service said it had begun vaccinating all its detainees, including the estimated 4,400 Palestinians held in its jails.
Jordan, which is home to Palestinian, Syrian and Iraqi refugees, launched its own vaccination campaign earlier this month.
It says it hopes to provide free vaccines to a quarter of the country's 10 million population, including foreign residents.
