NAFDAC Debunks Claim Of Mercury In Children Vaccines

National Agency for Food and Drug Administration and Control (NAFDAC), has debunked a report claiming that children in Nigeria were being administered a vaccine that contains 40 per cent mercury which was prescribed by foreign organisation.

The director-general, NAFDAC, Prof Mojisola Adeyeye, in a press statement said mercury is a metal and as such cannot be used as an element or as a component of vaccines.

The basic components of vaccines are antigens, adjuvants to improve immune response, antibiotics to prevent contamination during manufacturing, preservatives, and stabilizers, Adeyeye revealed, adding that thimerosal a mercuric compound which is a preservative used in multi dose vaccines contains a different form of mercury called ethyl mercury.

“As a vaccine preservative, thimerosal is used in concentrations of 0.003 per cent to 0.01 per cent, (for example, thimerosal content allowed in vaccines is between 30 parts to maximum of 100 parts out of million parts of the vaccine formula).

Thimerosal is a mercury-based preservative that has been used for decades in the United States in multi-dose vials (vials containing more than one dose) of medicines and vaccines,” she explained.

She averred that there is no evidence of harm caused by the low doses of thimerosal in vaccines, except for minor reactions like redness and swelling at the injection site.

“However, in July 1999, the Public Health Service agencies, the American Academy of Paediatrics, and vaccine manufacturers agreed that thimerosal should be reduced or eliminated in vaccines as a precautionary measure,” she added.
