The 37-year-old 'Wannabe' hitmaker has teamed up with UNICEF and bosses at a baby products company in their campaign to provide vaccinations to countries where the spasm-inducing infection can prove deadly for mothers and their babies, reported Contactmusic.
The singer, who is a mother to two sons - Beau, six, and Tate, two - has voiced her support for the cause in a bid to raise awareness and to encourage families worldwide to join the campaign.
"UNICEF and Pampers have been working together now for ten years and in that time amazingly they have eliminated it (tetanus) in 10 countries and we have saved millions of mothers and newborn babies all over the world," Bunton said.
