The Director-General, National Agency for Food and Drug Administration and Control (NAFDAC), Prof. Mojisola Adeyeye said that the agency had granted approval to Serum Institute Pvt. Ltd. (SIIPL) R21 malaria vaccine for the treatment of malaria in Nigeria.

At a news conference in Abuja on Monday, Prof. Adeyeye said that the granting of registration/approval was in line with the agency’s mandate as stipulated by its enabling law — NAFDAC Act CapN1, Law of the Federation of Nigeria (LFN) 2004.

She stated that it became necessary to grant approval for the vaccine following the 2021 World Malaria

According to her, Nigeria had the highest number of global malaria cases of 27 per cent, and the highest number of deaths stood at 32 per cent of global malaria deaths in 2020.

Prof. Adeyeye added that Nigeria accounted for an estimated 55.2 per cent of malaria cases in West Africa in 2020. She explained that the estimated number of malaria deaths stood at 619000 in 2021 compared to 625000 in 2020.

“Malaria is transmitted throughout Nigeria, with 97 per cent of the population at risk. The duration of the transmission season ranges from year-round transmission in the south to three months or less in the north,’’ she stressed.

She said that the Marketing Authorisation Holder’s (MAHs) for the vaccine is Fidson Healthcare Ltd, which had the agency’s Drug and Related Products Registration Regulation 2021.

The R21 malaria vaccine according to Adeyeye, is an adjuvanted protein vaccine presented as a sterile solution.

She explained that “a dose, which is 0.5ml, is composed of R21 Malaria antigen 5µg and Matrix-M1 50µg as an adjuvant filled in a vial as ready to use liquid formulation for intramuscular injection.’’

She said that the vaccine is indicated for prevention of clinical malaria in children from five months to 36 months of age, adding that the storage temperature of the vaccine is 2-8 °C.

The NAFDAC boss said the agency had several pathways for registration of vaccines, in line with the agency’s guideline for registration of Imported Drugs, Vaccines and IVDs under Collaborative Registration Procedure.

Adeyeye said the agency received the dossier of the R21 Malaria manufactured by SIIPL and subjected it to independent review at two different levels.

She added that as a matured regulatory agency, it is expected as part of global benchmarking that external advisory committee was put in place to give advice upon invitation on certain functions of the agency.

NAFDAC boss stated that as a new biological molecule being given consideration for full registration, the independent review by an external body became imperative to further safeguard public health.

The external advisory body known as NAFDAC’s Vaccine Advisory Committee (NEVAC) is made up of four highly recognised, well-published experts from Nigeria’s tertiary institutions, she said.She listed the institutions where the advisory body members were selected as Nnamdi Azikwe University, Awka, Anambra State; University of Lagos, Lagos State, University of Ibadan, Oyo State and Usman Dan Fodio University, Sokoto, Sokoto State.

Adeyeye said that the agency also had in-house Vaccine Review Committee (NEVAC) extracted from different directorates of NAFDAC to oversee, evaluate, as well as carry out clinical trials on vaccine before approval was made.

She said that the dossier was reviewed using WHO standard across relevant domains, in addition to the European Medicines Agency guidelines (where appropriate), scientific rigor on the vaccine.

According to her, the review of NAFDAC’s committee has always been guided by the same international standards and best practices with the same modality of independent review by members.

She said that the committee also independently scored the assessment as satisfactory, which was then forwarded to the director-general and that upon submission of the reviews of both committees, the NAFDAC boss called for a joint review session on April 14.

Adeyeye said that the joint review process provided the opportunity to harmonise the assessments, the outcomes of the reviews were discussed, and the recommendations and queries/clarifications were consolidated to be referred to the manufacturers.

The R21 Malaria Vaccine dossier, she affirmed complied substantially with best international standards with which the dossier was benched-marked.

She added that the Joint Review Committee concluded that the data on the R21 malaria vaccine were robust and met criteria for efficacy, safety and quality.
