Summary

The 'Experimental Human Pneumococcal challenge' (EHPC) model is a way of putting drops of bacteria into the nose. Investigators have studied this model of putting bacteria in the nose safely in over 1500 volunteers over the past decade with no serious side effects and now want to test the model using a different strain of the bacteria that is commonly found in the community, SPN3.

The aim of this study is to determine how much pneumococcus is needed to achieve nasal colonisation and how long the bacteria live in the nose for before natural immune responses eradicate them. By doing this, Investigators will then be able to test how well future vaccines prevent colonisation with pneumococcus. Investigators want to learn more about how the immune system responds to nasal colonisation with pneumococcus, again to help with development of new vaccines.

Conditions

  • Streptococcus Pneumonia

Interventions

OTHER

SPN3 innoculation

Healthy adult participants aged 18-50 (inclusive) will be inoculated with pure culture of well-characterised, fully sequenced amoxicillin-sensitive SPN3. They will be observed for safety and development of pneumococcal colonisation
