Nine female health workers in Kano, Nigeria were brutally killed while on a polio vaccination routine exercise on February 8.
Nobody has claimed responsibility for the attacks yet.
The killing of the women in Kano has reignited the controversy surrounding oral polio vaccination.
However, this controversy is not peculiar to Nigeria alone.
In 2003 the polio endemic was limited to only seven countries- Afghanistan, Egypt, India, Nigeria, Niger, Pakistan, and Somalia.
In 2013 however, all the other countries have successfully kicked out polio except Nigeria, Pakistan and Afghanistan.
In late 2012, an estimated twelve health workers in all, administering oral polio vaccines were killed in a series of attacks in Pakistan.
The origin of anti-polio vaccines like earlier vaccines for Smallpox, Chickenpox, Measles, Diphtheria, Tetanus and a host of others are as old as the development of vaccines themselves.
It is believed religious motives may have played a part.
