The News Agency of Nigeria (NAN) reports that the National Primary Healthcare Development Agency on said as at Dec. 8, 3.5 million eligible Nigerians have been fully vaccinated against COVID-19.
The agency also said that 6.6 million Nigerians had also taken the first dose.
The Executive Director, NPHCDA, Dr Faisal Shuaib, said the Federal Government had adequate doses of vaccines in-store to cover a large percentage of the population, adding that the country was awaiting about 57 million doses of the vaccine.
According to him, the country needed to vaccinate about 70 per cent of the overall population to reach herd immunity against the virus.
“The risk this poses to the nation is that it would give a chance for mutation of the virus. The vimutates in an environment where herd immunity is low. And for us as a nation, we have only achieved 3.5 million for the second dose which is very low. This is why mutation can happen so fast.
“We have more than enough vaccine in Nigeria for now. We also have a pool of vaccines almost 57 million that are awaiting shipment. There is about 40 million already in the country and we have secured about 90 million doses.
