Components of a vaccine
- Used to inactivate viruses (e.g.IPV) and to detoxify bacterial toxins, such as the toxins used to make diptheria and tetanus vaccines
- During production, a purification process removes almost all formaldehyde in vaccines
- The amount of formaldehyde in vaccines in several hundred times lower than the amount known to do harm to humans, even infants. E.g., DTP-HepB+Hib”5-in-1″ vaccine contains less than 0.02% formaldehyde per dose, or less than 200 parts per million.
