- Scientists are pushing for the development of a new vaccine for Lyme disease.
- A first-generation vaccine worked pretty well but was pulled from the market in 2002.
- The number of Lyme disease cases has been increasing every year.
It's tick season again, which means it's also Lyme disease season, and that puts outdoorsy people on edge.
The tick-borne illness, after all, brings fevers, aches and other nasty symptoms that, for about 10 percent of victims, last for months or more.
Doctors know a lot about Lyme and the bacteria that transmit it. Yet, there is no human vaccine for the disease -- at least not anymore. While there is a highly effective vaccine available for dogs, a series of unfortunate events doomed a first-generation human vaccine, which was pulled from the market in 2002.
As numbers of Lyme cases continue to rise each year, some scientists are pushing to bring back a Lyme vaccine, either in its old form or in a new one. Failing to offer a vaccine, they say, is failing the many millions of people who live in the vicinity of deer ticks.
