The Global Polio Eradication Initiative (GPEI) is extremely saddened that two committed frontline health workers were killed while delivering vaccines in Quetta, Pakistan. We extend our deepest condolences to their family. The delivery of health care is impartial and any attack against health workers is an attack on the children of Pakistan, whose very lives health workers are working to protect. The GPEI remains committed to supporting the government and people of Pakistan in continuing their important work to stop polio for good.
