Why FG may not rush to give Nigerians COVID-19 vaccines —Scientists Yusuff Moshood Nigerian scientists say that immunising Nigerians with COVID-19 vaccine when clinical trials have not been done in the country is very risky and should be reconsidered. They also expressed worries over its likely long-term effects. Nigeria expects its batch of vaccines by first quarter of 2021, with the Director-General of the National Centre for Disease Control, Dr. Chikwe Ihekweazu, saying that 20 percent of the population would have access to the vaccine. Speaking on the issue, a virologist at the Lagos University Teaching Hospital, Prof. Sunday Omilabu; and a Pharmaceutical Research Scientist with the National Institute for Pharmaceutical Research and Development, Abuja, Prof. Martin Emeje, are of the view that immunising Nigerians with COVID-19 vaccine when clinical trials were not done in the country is very risky and should be reconsidered.
