You may have heard about how vaccines are made – something about growing a virus in an egg, right? Unless you’re in the medical profession, the “how” of this process might be a bit of a mystery. In fact, hatching a virus out of an egg is pretty straightforward.
This photo, from the 1967 Inside Baylor Medicine, courtesy of the Baylor College of Medicine Archives, shows a researcher inoculating an egg with rubella – the “R” and MMR. Investigators inject the virus into a chicken egg, where it grows for a few days before the fluid inside the egg is harvested for research purposes.
If you’ve taken a child to a pediatrician for their MMR vaccine, they’ve benefited from research like this. The first rubella vaccine was licensed in 1969, just two years after this picture was taken.
