Who discovered vaccine for polio menengitis?

The vaccine for poliomyelitis (polio) was developed by Dr. Jonas Salk in the early 1950s. Salk's inactivated polio vaccine (IPV) was first tested in 1954 and became widely available in 1955. Later, Albert Sabin developed an oral polio vaccine (OPV) that became popular for mass immunization campaigns. Both vaccines have played crucial roles in reducing polio incidence worldwide.
