Now Salk could speed up his research. Using formaldehyde, he killed the polio virus but kept it intact enough to trigger the body's response. On July 2, 1952, Salk tried a refined vaccine on children who'd already had polio and recovered.After the vaccination, their antibodies increased.t was cheaper to make and easier to take than Salk's injectable vaccine. In the U.S., cases of polio are now extremely rare, and ironically, are almost always caused by the Sabin vaccine itself -- being live, the virus can mutate to a stronger form.
