good point ! i retract my statement <| sep |> I ask the same question every time I listen to Top 40 radio . <| sep |> Woo Maleficent HSC , been waiting for this . <| sep |> In this case it matters because in Pakistan , vaccination teams are almost entirely female . This is because they travel house to house checking on any kids who live there , how old they are , which immunizations are needed , etc . Men can ' t do this because they couldn ' t gain entry to homes or speak to mothers about their children . The practice of purdah prevents women from speaking to unknown men . So the weight of the vaccination effort in Pakistan rests entirely on these women who put their lives at risk to make house calls . The situation is so bad that security teams are sent to protect the vaccination staff men carrying rifles and submachine guns to escort these women workers from door to door . But as you can see , this isn ' t a perfect solution . The security guards can only escort you to the door , they can ' t go inside , and what will you alone inside the house when the parents turn their guns on you ? It ' s a strange juxtaposition of the good and the bad . On one hand you have these brave women knowingly risking their lives to vaccinate children , for pretty pathetic wages . On the other hand you have these evil fucks who murder them .
