No vaccine is available yet for group B strains. A new vaccine composed of the purified polysaccharide linked to a protein has been developed for group A and group C meningococci. The new vaccines are very safe and induce high levels of protective antibodies in infants and young children. A large trial of the new group C vaccine is currently underway in the United Kingdom. All children under 18 years of age will be vaccinated with the new vaccine between November 1999 and November 2000.
Early results are very promising.
