In her clear and concise overview of the MMR/autism debate (Managers & Medicine , pages 4-5, 28 October), Jenny Bryan suggested that the question 'how serious is measles?' was central. The implication was that its being serious offers prima facie support for maximising the uptake of MMR immunisation.

But as she points out, there is an alternative: the single measles vaccine 'used routinely before. . . 1988'. The government's withdrawal of this, coinciding with concern about MMR, may be implicated in any future measles epidemic. The decision should be reversed.
