“If you’re a person who’s not vaccinated and a potential carrier, to protect the people, I have to sequester you in jail,” Duterte said late Monday. Village leaders should keep a list of those who refused to be vaccinated, he said.

If implemented, Duterte’s threat could be among the severest measures to boost inoculations in a nation where majority are unsure of or reject vaccines. Indonesia earlier this year moved to punish those who refuse shots with fines or delayed aid.

The Philippine leader halted plans to resume physical classes and retained mandatory wearing of face shields. Duterte said he will not obey the courts on how to manage the pandemic, after lawyers in the central province of Cebu questioned the national task force’s testing and quarantine protocols.

“The first wave has really depleted the resources of government,” Duterte said. “Another one would be disastrous for this country. That is why the stricter you are, the better.”
