Pakistani Prime Minister Imran Khan tested positive for Covid-19 on Saturday, two days after receiving his first vaccine dose, government officials said, urging people not to be deterred from getting vaccinated.

Pakistan’s vaccination roll-out has been met with widespread vaccine hesitancy, and Khan’s positive test could serve as a setback to the inoculation drive in the country of 220 million people, health experts said.

Health minister Faisal Sultan said Khan was “in good health” with a mild cough and fever and was self-isolating at home, adding that the 68-year-old Premier had likely been infected much before he got his first vaccine shot on Thursday. He said people should not link the Khan’s infection with the vaccine.
