You may satisfy the Varicella requirement in either of the following ways:

By vaccine

  • Two doses of the Varicella vaccine.
  • Doses must meet the following age/interval requirements:
    • First dose must be on or after your 1st birthday
    • Second dose must be at least one month after the first dose
  • If you only have one dose that meets the age/interval requirements, you still need to get an additional dose.
  • Note: since Varicella is a live vaccine, it is contraindicated in certain conditions (including if you are pregnant).

By titer (if you actually had chicken pox, or cannot find records for your past doses of the vaccines)

  • Blood titer for Varicella showing that you have immunity.
  • If your titer results do not show evidence of immunity, you will still be required to get any outstanding doses of the vaccine as indicated above.
  • Note: when reporting your titer results, remember that "positive" means "positive for immunity" and "negative" means "negative for immunity."
Not everyone who has chicken pox or shingles necessarily develops Varicella immunity, so a blood titer to prove that you are "positive" for immunity is required. A doctor's note stating that you had chicken pox or shingles is not sufficient.

If the Varicella vaccine or titer is not available in your country, or it is impossible for you to have it administered by the formal deadline:
