What the vaccination pass is (and isn’t)
1982
In the broadest sense, the initial release of the CVC achieves the following:
ACT
• It provides a digitally verifiable record that the person the pass was issued to is
considered vaccinated for COVID-19, up
until the pass expiry date. For the purposes of the CVC this includes:
• people who have received a suitable schedule of a recognised COVID-19 vaccination, including vaccinations
administered overseas, or
• a very limited number of people who are medically exempted from being vac
INFORMATION cinated for COVID-19.
• It could be used for any health status where we consider the holder to be treated the same as a vaccinated person, provided
we do not care for the ability for a verifier to be able to distinguish that status from a person who is considered vaccinated.
• It
does not provide assurance that the person presenting the pass to
OFFICIAL be verified is the person it was issued to.
• It
does not necessarily guarantee that the person is imm
THE une from COVID-19. They may still carry or transmit the virus while
immunised, or they may be exempt from vaccination.

Fewer may exclude people.

Different vaccinations may be effective for different lengths of time, and could
influence the pass expiry time
How many doses are required

Allowing after only one dose of any approved vaccine means people can get a pass,

INFORMATION
• If a full schedule, is the pass only valid after X days from the schedule being completed?
• How long after their last dose can they request a pass (before they would need to get another shot)?
