A regular paediatric vaccine could help to prevent meningitis in children and adults, new research has suggested.
The study, which was carried out at the University of Pittsburgh School of Medicine, US, showed that the injection - which is normally used to protect against common deadly infections - reduced rates of pneumococcal meningitis.
The authors discovered that, after the vaccine was introduced in 2000, signs of meningitis decreased in both children and adults.
Commenting on the finding, senior author Lee Harrison said that immunised children were "less likely" to carry pneumococcal strains at the back of their throats.
"When vaccinated children don't carry these virulent strains, they don't end up transmitting them to other children, their parents and grandparents," he said.
The pneumococcus bacterium is capable of causing pneumococcal meningitis - an infection in the brain and spinal cord membranes.
Most instances of pneumococcal meningitis occur in babies and young children that are aged under 18 months. Around one in five of those who develop the condition die, while a quarter are left with severe after-effects.
