Why isn't the Covid Vax being made the way the safe and effective Rabies vax is made. Both are viruses.---LINK

"The vaccine
How is the rabies vaccine made?
The rabies vaccine is grown in cells in the laboratory. Three different kinds of cells are used:

Human cells obtained from a single elective abortion performed in the early 1960s
Chick embryo cells
Fetal rhesus lung cells
After the virus is grown in these cells, it is purified away from the cells and treated with a chemical (called beta-propiolactone) that completely kills the virus. The rabies vaccine is, like influenza and hepatitis A vaccines, a "killed" viral vaccine. (see How Are Vaccines Made?).

Does the rabies vaccine work?
The rabies vaccine works remarkably well. Studies indicate that if the vaccine is given immediately and appropriately to someone who was bitten by a rabid animal, it is 100 percent effective."
