Yesterday's episode of "More or Less" (BBC Radio 4, now on iPlayer)
explained how the effectiveness figure is arrived at.
If you use the same methodology there's little difference between the
three approved vaccines, and one dose *is* highly effective.

Isn't the unknown the effectiveness if the second dose is changed from
within 3 weeks to within 12 weeks.
