Target follow-up duration
Target follow-up type
Description of intervention(s) / exposure
Participants will wear a ultraviolet radiation (UVR) absorbant wrist band which will measure UVR personal exposure for 5 days. Subsequently all participants will be vaccinated subcutaneously with 125mcg keyhole limpet hemocyanin (KLH) administered to a sun exposed part of the forearm. Participants will be recruited over a 52 week period.
Intervention code [1] 256161 0
Not applicable
Comparator / control treatment
We are correlating UVR exposure against immune response to vaccination. There is not control group.
Control group
Uncontrolled

Outcomes
Primary outcome [1] 258033 0
Humoral response to primary subcutaneous vaccination with Keyhole Limpet Hemocyanin (KLH). KLH-specific immunoglobulins (Ig) (Ig types M, E, G and subsets) will be quantified via enzyme linked immunoassay techniques.
Timepoint [1] 258033 0
KLH specific antibody titres taken at baseline (immediately prior to vaccination which follows the 5 days of UVR exposure measurement); 1 week and 3 weeks post vaccination
Secondary outcome [1] 263599 0
Delayed-type hypersensitivity (DTH) response to intra-dermal KLH will be measured in millimetres of skin reaction
Timepoint [1] 263599 0
Intradermal KLH given at day 21 post vaccination. DTH response read at 48 hours post intradermal KLH.
Secondary outcome [2] 263600 0
KLH specific T-cell response will be measured via lymphocyte proliferation assays and cytokine production.
Timepoint [2] 263600 0
Measured at baseline (immediately prior to vaccination) and day 21.
