These requirements prove you are protected against — and cannot pass on — the
infectious diseases you may encounter during your placement. Each one follows
the same five-part layout: what it is, what to submit, accepted proof, good to
know, and validity.

  <Card title="COVID-19" href="/immunizations-serology/covid-19">
    Proof of your primary series and any boosters your site requires.

    Proof of a completed polio series or immunity shown by a blood test.
  </Card>

  <Card title="Influenza (flu)" href="/immunizations-serology/influenza">
    Proof of this season's flu shot — a new dose is required each year.

</Cards>

**Start early:** blood tests and missing vaccine doses can take weeks —
some series need time between doses. Book appointments as soon as you know
your placement date.
