The implication is clear: Israel should be ensuring the palestinians get vaccinated, as we do our own citizens. Actually, it is more than implied; both reports say it explicitly. For instance, from the AP one:
Physicians for Human Rights-Israel, a group that advocates for more equitable health care, says Israel has a legal obligation as an occupying power to purchase and distribute vaccines to the Palestinians. It says Israel must also ensure that vaccines that don’t meet its own safety guidelines — like the Russian shot — are not distributed in areas under its control.
“Israel still maintains control over many aspects of the Palestinians’ lives, whether checkpoints, importing goods and medication, and controlling the movement of people,” said Ghada Majadle, the director of the group’s activities in the Palestinian territories.
