Vaccin: un nanopatch qui pourrait tout changer

Et si un petit carré de silicone à peine plus grand qu’un cachou pouvait changer la face du monde ?

Hérissé de 20 000 nano-aiguilles enrobées d’antigènes (le principe actif du vaccin), il déclenche une réponse du système immunitaire en sollicitant les cellules de la peau qui sont très sensibles.
