To create their vaccine, the researchers focused on the serotype 3 gene that codes for pneumolysin, a toxin produced by all pneumococcal strains.
The research, published in the international peer-reviewed journal PLoS Pathogens, found that pneumolysin, the toxin in the bacteria, also triggers an immune response.
