Deadly bacterial infections could be halved by giving personalised vaccines, scientists claim. Different strains of bacteria are found in across the world, and risk of infection will depend on where a person lives and their age. This means jabs could be modified to suit them. For example, there are more than 100 strains of Streptococcus pneumoniae, which can lead to pneumonia, sepsis and meningitis. Vaccines are currently based on a broad approach, but tailoring them to be more specific could improve them, new research suggests. It could also help combat the threat of antibiotic resistance, which is described by the World Health Organisation as one of the greatest threats facing humanity. Children currently have the pneumococcal (PCV) jab on the NHS when they are babies. But scientists say it could be improved (stock image) The study published in the journal Nature Microbiology analysed the bacterium Streptococcus pneumoniae, which claims around 30,000 lives a year. S. pneumoniae is often found at the back of the nasal cavity, where it is normally harmless. But when it migrates to other parts of the body, it can cause serious bacterial infections such as pneumonia, sepsis and meningitis. Infants and the elderly are most at risk.
