The 'Dejando Huellas' program has held vaccination fairs in nine municipalities across Puerto Rico since March 2025.^[1] Metro Puerto Rico reported the count on Sept. 8. The municipalities named are Bayamon, Barranquitas, Cabo Rojo, Toa Alta, Toa Baja, Canuy, Hatillo, Quebradillas and San Juan. The spread runs from the north coast to the west and into the mountain towns. The read here is that the list reaches both large municipalities and smaller ones, though the filing gives no dates for individual fairs or a tally of people vaccinated.
