You may have heard of the Iditarod dog sled race. The basis of the race is a commemoration of a run via dogsled of serum. Via Wikipedia :

"The most famous event in the history of Alaskan mushing is the 1925 serum run to Nome, also known as the "Great Race of Mercy." It occurred when a large Diphtheria epidemic threatened Nome. Because Nome's supply of antitoxin had expired, Dr. Curtis Welch refused to use it and instead sent out telegrams seeking a fresh supply of antitoxin. The nearest antitoxin was found to be in Anchorage, nearly one thousand miles away. To get the antitoxin to Nome, sled dogs had to be used for part of the journey, as planes could not be used and ships would be too slow. Governor Scott Bone approved a safe route and the 20-pound (9.1 kg) cylinder of serum was sent by train 298 miles (480 km) from the southern port of Seward to Nenana, where just before midnight on January 27, it was passed to the first of twenty mushers and more than 100 dogs who relayed the package 674 miles (1,085 km) from Nenana to Nome. The dogs ran in relays an average of 31 miles (50 km) each, with no dog running over 100 miles (160 km)."


Listening to the radio this morning I've heard of vaccine being sent from Anchorage to Seward via delivery van and into another area via floatplane. That has to be somewhere in Southeast Alaska since all our other outdoor water is solid right now. It is not totally impossible that the vaccine might find its way onto a dogsled, and if I hear of that happenin, I'll be sure to mention it.
