Reminds me of the documentary Cold Case Hammarskjold where they discover the apartheid era South African government had set up fake medical clinics to infect (Black) Africans with HIV.
> In March health workers administered the vaccine in a poor neighbourhood on the edge of Abbottabad called Nawa Sher. The hepatitis B vaccine is usually given in three doses, the second a month after the first. But in April, instead of administering the second dose in Nawa Sher, the doctor returned to Abbottabad and moved the nurses on to Bilal Town, the suburb where Bin Laden lived.
I don't know if that changes anything. It does appear that they didn't "effectively" vaccinate people when it was convenient.
