While Israel has already become the world leader in vaccinations per capita, Palestinians in the West Bank and the Gaza Strip have yet to secure their first supplies.
Yasser Bozyeh, the Palestinian general director of public health, told Reuters that in addition to reaching an agreement in principle with AstraZeneca, the Palestinians had also sought supplies from Moderna, Johnson & Johnson and Russia, which has developed the Sputnik V vaccine.
Supplies would also come through a World Health Organization vaccine program for poor and middle income countries.
There was no immediate response from AstraZeneca to an emailed request from Reuters for comment.
The official, Gerald Rockenschaub, head of the WHO office in the Palestinian territories, said Israel indicated it would explore the option.
