This question seems to be from a unit about Henrietta Lacks' cells.
There are many polio viruses that have no effect on humans. Her cells (HeLa) allowed the growth of polio viruses and made it possible to determine which strain produced the devastating effects. When that was determined, the vaccine could be made.
Vaccines are not limited to viruses. Some of the bacterial diseases for which there are vaccines include: tuberculosis, meningitis, tetanus, whooping cough, typhoid, cholera, anthrax, etc.
