Soar Hawkfury at Agmar's Hammer in the Dragonblight wants you to use the Pack of Vaccine to vaccinate 5 Snowfall Elk and 5 Arctic Grizzlies.
5x Snowfall Elk Inoculated
5x Arctic Grizzly Inoculated
Inside this pack are several vials containing the vaccine that Sintar created. I now want you to search the nearby woods for Snowfall elk and arctic grizzlies. When you locate the animals, find a safe distance and throw a vial in their general direction. The vial will shatter and release a fine gas that will act as the inoculating agent. The beasts merely have to step inside the gas and they will be vaccinated - ultimately saved.
Inoculate as many of the beasts as you can and return to me.
