The incredibly frustrating reason there’s no Lyme disease vaccine
Lyme has quickly become one of the most common infectious diseases in America, with many as 300,000 people infected every year. And public health officials fear the bacterial infection, which jumps from ticks to humans, will only spread farther and faster as climate change makes more parts of the US habitable for ticks. Lyme can be treated with antibiotics. And there are many ways to prevent tick bites. But there’s no vaccine available if you want extra protection against the disease (unless you’re a dog).
