AskScience AMA Series: Let's talk ticks! We are experts from WebMD and Johns Hopkins Medicine here to answer your questions about preventing tick bites and Lyme disease - Ask Us Anything!

Hello, Reddit. I am Dr. Michael Smith, WebMD's chief medical director. Have a question about ticks? We'll cover everything from ways to protect from tick bites to first aid steps to take if one bites you. AMA! 

Hi Reddit, we are John Aucott, and Mark Soloski and we are researchers at Johns Hopkins Medicine studying ticks and Lyme disease. Ever wonder why Lyme disease and other tick-borne infections have become so common? What makes some people get sicker than others? And how can we prevent and diagnose Lyme disease - that the classic bull's eye target is not as common as people think? We cover everything from fundamental research to clinical treatments - AUA!

We will begin answering questions at 12pET (17 UT). Ask us anything!

I've read a few times that there is a perfectly good vaccine for Lyme's that is essentially held back because of anti-vax hysteria. Is this true, and if so, what are the prospects for getting it to happen?
