The Kelvinator became the first mass-produced home refrigerator. In 1919 General Motors bought a small refrigerator company called Frigidaire, which also made compression refrigerators. By 1920 about 75,000 homes had refrigerators
Vaccine should always be kept in refrigerators unless the one who made it says otherwise.
Sanitary storage containers work well, as do refrigerators and storage sheds.

Well, you could put something hot in a thermos, and something cold in a cooler bag, wich is basically lined with thermal material. Things kept in thermal things won't stay the same temperature forever.
Your refrigerator has areas that are colder and warmer and some areas have more humidity. In most refrigerators, the pockets/shelves in the door are the warmest area in the fridge this is because of their closeness to the exterior of the fridge as well as the fact that these items are exposed to the temperature in your home every time the door is opened. Eggs should not be stored in the door because of this fluctuation in temperature. The lower shelves in the fridge are the coldest because cold area "falls" and hot air "rises". Items requiring more cold should be kept on the lower shelves. Vegetables require even moisture and that is why they are kept in the enclosed vegetable bins in the bottom of the fridge.
