Data have been ranked by order of the sum of diary symptom score entered after inoculation. Subject number 7 scored more than 12 points but did not meet the criteria of a progression of the symptom score, i.e. a 4‐point increase on 2 consecutive days, after inoculation. *: Score before and day 1–4 after inoculation and total score day 1–4.
