Officials wrapped up the third round of vaccine injections for swamp cancer for the Chincoteague ponies.
Denise Bowden with the Chincoteague Volunteer Fire Company told the Salisbury Daily Times that the last injection was given on Saturday.
She adds there have been no adverse effects from the shots so far.
The vaccinations began in April after the deaths last year of a number of ponies from the fungus like disease that leave lesions on their bodies that can be painful and run into the thousands of dollar to cure.
The injections come as officials prepare for the annual pony penning auction next month in Chincoteague.
