Tetanus is a vaccine-preventable disease that yearly causes a total of 309,000 deaths. Of particular concern is maternal and neonatal tetanus (MNT), which can be prevented through immunization of the mother in pregnancy. In 2000, neonatal tetanus alone was responsible for an estimated 200,000 deaths. ⋯ Through SIAs, about 17 million women have been reached with at least two doses of TT vaccine in the past 3 years, and it is estimated that another 200 million need to be targeted in the years to come. SIAs should substantially reduce the burden of disease. Countries will also have to improve their existing immunization and clean delivery programs to ensure that the elimination of maternal and neonatal tetanus is maintained.

Maternal immunisation could help to prevent the 2-3 million neonatal and early infant deaths that occur in the developing world each year. Determining the causes of neonatal and early infant deaths in developing countries is difficult as most occur at home. However, it is likely that at least half are due to infections, several of which might be prevented by maternal immunisation. ⋯ Nevertheless, the potential of maternal immunisation to prevent early infant deaths in developing countries needs to be fully explored. The incidence of pneumococcal infections is high in many developing countries and about 25% of these infections occur at an age before protection could be anticipated following vaccination with a pneumococcal conjugate vaccine in infancy. Thus, a strong case can be made for a trial of the effectiveness of maternal immunisation with a pneumococcal vaccine in preventing serious illness or death in young infants in developing countries.
