The National Agency for Food and Administration and Control (NAFDAC) has clarified the source of COVISHIELDTM Vaccine, saying it is the same as Astrazeneca Oxford University Vaccine being used by many countries across the globe.

In a statement Sunday, signed NAFDAC’s Director General, Prof. Mojisola Adeyeye and sent to African Community News, the Agency said AstraZeneca and Oxford University (AZOU) originally developed the ChAdOx1 recombinant adenoviral vector vaccine to be used for prevention of COVID-19 disease, adding that AZOU gave the license of its vaccine to Serum Institute of India PVT Ltd (SIIPL) to manufacture this vaccine at commercial scale.

Explaining further, NAFDAC said that- “SIIPL is the largest vaccine manufacturer in the world and the company got the license by signing manufacturing agreement with AstraZeneca (AZ)/Oxford University to manufacture this vaccine. SIIPL gave the vaccine the trade name COVISHIELDTM.

“COVISHIELDTM is the result of a cooperation and a technology transfer from AstraZeneca – University of Oxford to SIIPL.

“Serum Institute of India Pvt. Ltd. is now the world’s largest vaccine manufacturer by number of doses produced and sold globally (more than 1.5 billion doses) which includes Polio vaccine as well as Diphtheria, Tetanus, Pertussis, Hib, BCG, r-Hepatitis B, Measles, Mumps and Rubella vaccines. Vaccines manufactured by the Serum Institute are accredited by the World Health Organization, Geneva and are being used in around 170 countries across the globe in their national immunization programs, saving millions of lives throughout the world.

“Both COVISHIELD™ manufactured by Serum Institute of India Pvt Ltd and COVID-19 Vaccine AstraZeneca manufactured by AstraZeneca are the same vaccine – ChAdOx1 nCoV- 19 Corona Virus Vaccines (Recombinant).

“COVISHIELDTM was granted Emergency Use Listing (EUL) by the World Health Organisation on 15th February, 2021 and it is one of the listed vaccines under the COVAX Facility,” Prof. Adeyeye stated.
