An mRNA-based anti-tick vaccine
Interestingly, there was a Lyme vaccine in the late 90s that was pulled from the market:https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2870557/I think it’s a shame it was withdrawn, with a low effectiveness of 80% and even requiring annual boosters I’d view that as a great option if I lived somewhere with deer ticks. Lyme disease is scary.
