TIL the reason you don’t find much Lyme’s Disease in California is not because we don’t have Ticks, or Lyme Disease Vectors; but rather: because the Western Fence Lizard (if you live anywhere in California this is your regular Garden Variety Lizard) has adapted a passive immune response that makes their blood lethal to Lyme Disease Bacteria. Any Tick that feeds on one gets its gut cleansed of Lyme Disease as a side effect.
There is a new vaccine going into Phase 3 trials from Valneva and Pfizer as well as a monoclonal antibody-based prophylactic treatment being researched at UMass!
