COVID-19 vaccines aim to prevent COVID-19 disease by triggering an immune response.

COVID-19 vaccines are being developed following the same legal requirements for quality, safety, and efficacy as for all other vaccines.

Like all vaccines, the effects of COVID-19 vaccines are tested first in the laboratory, including in animals, and then in human volunteers.

The National Regulatory Authority, such as NAFDAC, is the agency in charge of evaluation and supervision of medicinal products. It will evaluate COVID-19 vaccines against the same high standards as for all other vaccines before they can be released for use. NAFDAC will continually monitor side effects in people who have received COVID-19 vaccines and identify and evaluate new information that arises on the benefits and safety of COVID-19 vaccines promptly.
