For the past couple of years, I’ve been wondering why the Vet can vaccinate our dog for Lyme*, but the best our doctor can offer is a dose of doxycyline, ex post facto. Why is it, despite the spraying and tucking and checking out the nooks and crannies post-walk, a simple stroll on a glorious summer day is more of a health risk for humans than for their best friend? (And here in Western MA, it’s a big risk.) Why isn’t there a human Lyme vaccine? In part, there isn’t a human vaccine thanks to the anti-vax movement.
