This topic sound as if it's new in the Nigeria system, the system has been bastardized to the point that many healthcare collect money for immunization despite is stated clearly to be free if you refuse paying they end up telling their branch don't have that particular immunization, I noticed some irregularities in the health sector I therefore made conclusion that it takes revolution to change the narrative because all sector if the Nigeria system have their magic they uses to extort or deprived citizens from gaining full benefits of what seem to be their right, the worst of this they have principle of not taken transfer you must pay in cash so that you won't have evidence even if the government attached small fees those in charge increase to have their cut making things difficult for citizens corruption is from the root to the top, only when capital punishment is put in action to all who fall into this corruption that will reduced the corruption.
in Nigeria immunization is not free of course, people has moved on, there are many things happening in our health sector, the staffs are criminals, Government will import drugs, nurses and doctors will sell them off and request for new one and even if the drugs are replaced, they will still do the same thing, the corruption in this country has effected every sectors, recently a woman told me that if not for one thing that she would've not bothered herself going for immunization, I ask her what happened, what she told me, got me thinking, every office in Nigeria has become an avenue to make money, the worst of it all is that, the people doing this are not afraid of anything because they know that corruption is a normal thing here.
