Brief summary

We will recruit up to 3000 participants including ideally 200-300 clinically proven COVID cases to assess 1) Antibody prevalence, performance and responses 2) active T-cell prevalence, responses and types 3) cardiac outcomes over the next 3 years in proven COVID cases versus “others”. Event rates will be obtained through Ministry of Health, GP, DHB, Birth Death & Marriages and phone or email follow up with participants. This will provide a biobank to draw upon for future investigator inspired work.

Interventions

Participants aged over 18 years entering New Zealand, or working at the borders and those who have had COVID-19 will be asked to provide blood and saliva sample at yearly intervals over a 3 year period. They will also be asked to complete a 10 minute health questionnaire and consent to follow of of their health by direct contact and remote access through the Ministry of Health, GP, District Health Board, Laboratory, Pharmaceutical, Births and Death & Marriages administrative records
