Nigeria, March 25 -- It wasn't planned. I was seeing off my neighbour and friend on Thursday evening when one of the officers of our estate residents' association called out to me.

He was in knickers and shirtsleeves, with his right hand clutching his left shoulder. "I've just been vaccinated," he said. "Would you like me to put your name forward for it tomorrow?"

After what I have seen in the last one year - COVID-19 related deaths first becoming statistics, and then statistics becoming people, and people having faces, and faces becoming friends and relatives - news of the discovery of vaccines was a huge relief.

But vaccines, like many good things, are made abroad, while rumours and myths about them are manufactured locally.

Nigeria...
