From Ed Shields, Neebing, Ontario, Canada
I live in a very bad tick region and I spend hours each day outside always worrying about getting bitten. I was shocked by the idea that anyone wouldn’t want a vaccine that worked in part by giving them an unpleasant reaction to a tick bite. A choice between getting a bad disease from a tick or simply getting an itch seems a no-brainer(21 June, p 36).
