The Nigerian Medical Association has called for the clinical trial and testing of Covid-19 vaccines before giving them to Nigerians.
NMA President, Professor INNOCENT UJAH, made the call, as the Federal Government expects to receive some doses of Covid-19 vaccines by January next year.
Professor UJAH said he cannot say whether African countries were involved in the clinical trials during the process of developing the Covid-19 vaccines.
He said the differences in biology, environment, and genetic composition require Nigeria to do its own clinical trials before using the vaccines on citizens.
