  • 2. Aged 18-50 yrs - ages chosen to minimise the risk of pneumococcal infection
  • 3. Speak fluent English to ensure a comprehensive understanding of the research project and their proposed involvement, in order to minimise any communication issues to maximise participant safety

排除标准

  • 3. Egg allergy (as per influenza vaccines patient leaflet)
  • 4. Previous significant adverse reaction to any vaccination/immunisation
  • 5. Close contact with at risk individuals (children under 5 years, immunosuppressed adults, elderly, chronic ill health) – to minimise risk of pneumococcal transmission and transmission of virus for those receiving the LAIV
  • 6. Current regular smoker (smokes daily)
  • 7. Significant smoking history [defined as someone who has previously smoked more than 20 cigarettes per day for 10 years or the equivalent (>10 pack yrs)] – to minimise risk of bronchoscopy or pneumococcal disease
  • 8. Asthma (on regular medication) or respiratory disease – to minimise risk of bronchoscopy or pneumococcal disease
  • 9. Pregnant to minimise the risk of pneumococcal disease
  • 10. Women of childbearing potential (WOCBP) who are not deemed to have sufficient, effective birth control in place for 1 month prior to vaccination and 1 month after the final vaccination
  • 11. Allergic to penicillin/amoxicillin/ gentamicin
