By Joseph Erunke, Abuja

The National Agency for Food and Drug Administration and Control, NAFDAC, has given conditional approval for use of Janssen COVID-19 vaccine in Nigeria.

The conditional emergency use authorization of the vaccine, according to the agency’s Director-General, Prof. Mojisola Adeyeye, Tuesday, came after a thorough evaluation of the product.

Adeyeye said after the evaluation, NAFDAC Vaccine Committee concluded that the data on the vaccine were robust and met the required standard for use in the country.

The Janssen COVID-19 vaccine is the third vaccine recommended for administration in the country.

The NAFDAC boss said unopened vaccine vials can be stored and/or transported frozen at -25°C to – 15°C for up to 24 months and 3 months when stored at 2 to 8°C.

She said the data also showed that the vaccine’s known and potential benefits outweigh its known and potential risks thereby supporting the manufacturer’s recommended use.

“The Janssen COVID-19 vaccine is administered as a single dose. Results from a clinical trial involving people in the United States, South Africa, and Latin American countries found that the Janssen COVID-19 vaccine was effective at preventing COVID-19 in people from 18 years of age.

“The Phase III clinical trial involved over 44,000 people. Half received a single dose of the vaccine and half were given a placebo (a dummy injection). People did not know if they had been given Janssen COVID-19 Vaccine or placebo,” she said.

She further explained that: “The trial found a 67 percent reduction in the number of symptomatic COVID-19 cases after two weeks in people who received Janssen COVID-19 Vaccine. The most commonly reported side effects were pain at the injection site, headache, fatigue, muscle aches, and nausea. Most of these side effects were mild to moderate in severity and lasted 1-2 days.”

Adeyeye said NAFDAC, in line with its pharmacovigilance and safety monitoring plan for COVID-19 vaccines, will closely monitor and subject the Janssen COVID-19 Vaccine to several activities that apply specifically to COVID-19 vaccines.

“Manufacturers are required to provide monthly safety reports in addition to the regular updates generated by NAFDAC activities, she said.

She said the Federal Ministry of Health and the National Primary Healthcare Development Agency, NPHCDA will announce when the vaccine becomes available for use in Nigeria.
