She said three additional vaccines were currently undergoing evaluation, “but the evaluation on AstraZeneca shows that the vaccine is effective against the UK variant of the virus, which has been reported in Nigeria.”

According to her, the South African variant has not been reported in Nigeria and that the agency has over 30 herbal medicines undergoing review for listing.

“The Oxford AstraZeneca vaccine, also known as ChAdOx1 nCoV-`9, or AZD1222, is a viral vector vaccine. Scientists used an adenovirus, originally derived from chimpanzees, and modified it with the aim of training the immune system to mount a strong response against SARS-CoV-2 (the virus that causes COVID-19).

“Nigeria is expected to get the first batch of the COVID-19 vaccines by the end of February.
