Pakistan's Vaccine Worries: Rich People And Conspiracy Theorists

Keeping an eye on vaccine snatchers. Turning dial tones into public health messages. Selling vaccines to the wealthy to make sure they don't elbow their way to the front of the line.

These are among the strategies being employed by Pakistan as it gears up for an extraordinary task – acquiring enough vaccines for its enormous population of 220 million.

"A lot of things can go wrong" with Pakistan's vaccine rollout, says Fatima Akram Hayat, a health adviser to the government's COVID-19 response team. "Even if it goes very well, considering the costs, considering the far-flung areas, considering how big the population is, I don't think [nationwide immunization will] happen in 2021," she says.
