All staff influenza and Covid-19 vaccination information is inputted into the Welsh Immunisation System (WIS). This is a national database developed by Digital Health and Care Wales (DHCW) in response to the Covid-19 pandemic and the mass vaccination programme. Its use has been extended to also record information about influenza vaccinations. The WIS does not record specific information about a Health Board employee’s host Clinical Board, department and staff group. Therefore, to allow us to monitor vaccination uptake amongst employees, data on your influenza and Covid-19 vaccinations within the WIS is matched to your ESR record (for Covid-19 vaccination) and to the Occupational Health database (for influenza vaccinations) which both contain the required information about your Clinical Board, department and staff group. The matching process is necessary to link your WIS vaccination record with your ESR / occupational health record. Once matching is complete, reports can be prepared on uptake by Clinical Board, department and staff group. Reports are aggregated and anonymised so no individual is identifiable through this reporting process. DHCW will provide data from the WIS to the Health Board about the influenza and Covid-19 vaccinations received by CVUHB staff members.
Your individual Covid 19 vaccination status will remain in the WIS system and not enter the occupational health system and is therefore not accessible to occupational health staff. Your individual influenza vaccination status will be transferred to the occupational health database from the WIS system as it is the responsibility of the Health Board’s occupational team to offer all staff an influenza vaccination in line with Welsh Government policy. Influenza vaccination is therefore included in a staff member’s vaccination history alongside their other vaccinations required for occupational purposes. If an NHS employee obtains an influenza vaccination from the Health Board but is not employed by the Health Board, recording the influenza vaccine given in the occupational health database enables the occupational health department to cross-charge other NHS organisations and report uptake to them. This is only possible when the influenza vaccination is recorded on the occupational health system. For staff who receive their influenza or Covid-19 vaccination(s) from a Health Board area other than Cardiff and Vale University Health Board or for staff who decline a vaccination, there is a self-certification process available at Flu vaccine and COVID-19 autumn booster - Flu vaccine and COVID-19 winter booster - Cardiff and Vale University Health Board (nhs.wales). This process is not mandatory but once notified, will be recorded in the occupational health database accordingly.
