The primary vaccination arm (reference group) includes participants who have never been vaccinated or have had 1 YF vaccination; secondary vaccination arm includes participants who have received 1 or 2 vaccinations; and multiple doses arm includes participants who have received >2 revaccinations. Participant subgroups indicate number of days or years since vaccination (in parentheses; d0 for those never vaccinated).
