First-Ever mRNA Vaccine for Lyme Disease Shows Promise in Guinea Pigs

It is really common here in Denmark. Almost half the adult people I know have had Lyme disease atleast once and most people who work in the forrest has had it several times. Because it is so common, we are very good at spotting the signs, so we can get the treatment in the early stages. We don’t have any apex predators, so there are way too many deer in Denmark and hence way too many ticks. Everytime I go to the forrest to collect mushrooms, I have 5-10 ticks on me. We check each other when we get home. Where we have a tick, we draw a circle around the bite, so we can check if a rash is forming after about 10-14 days. I would take that vaccine in a heart beat.


Lyme disease terrifies me. I know multiple who have it that are basically disabled, but insurance won’t help them out.


Important note regarding this vaccine: it is not a vaccine for Lyme disease, but rather a vaccine to illicit an immune response to tick saliva. After you get the vaccine your body will immediately start to get a red, itchy spot where a tick bites you (think a similar reaction to a mosquito bite), so you’ll know you’ve been bit and be able to remove the tick before it transmits Lyme disease (which takes about 36 hours of being attached usually). However, once you have been infected by Lyme disease, this vaccine does nothing for you. It’s an interesting approach, though perhaps not as directly useful as an actual Lyme disease vaccine would be.


Title is incorrect, vaccine is based on tick salivary proteins, not Lyme causing bacteria.


Wait. Isn’t lyme a bacterial disease?
