The first mRNA ‘anti-tick‘ vaccine
The first mRNA ‘anti-tick‘ vaccine - just published in Science Translational Medicine by Prof. Erol Fikrig’s research group (Yale University)
In their study, the authors vaccinated guinea pigs with a cocktail of nineteen mRNAs encoding salivary proteins packaged in lipid nanoparticles. This mRNA ‘anti-tick‘ vaccine promoted antibody responses against salivary proteins in guinea pigs, which consequently suppressed their infection by Borrelia. The vaccine elicited immediate swelling and itching. Such a response could help to alert hosts to ticks quickly and prevent Borrelia transmission.

Petr Kopáček and colleagues were invited to write a Focus article to this pioneering study which was published in the same issue of this journal.
