Everybody knows vaccines need to be kept cool, but not everyone monitors the temperature effectively.

If you’re wondering about the importance of proper vaccine refrigeration, you might want to take a look at this 1983 report on vaccine storage conditions in Montreal.  In outbreaks in 1979 and 1980, 60 percent of the children who came down with measles had been earlier vaccinated.  That raised questions about the potency of the vaccine, so researchers took a look at storage conditions in vaccine refrigerators in Montreal. They visited twenty locations and found that more than 80 percent of the sampled vials were held above 8 degrees C.
