The Sabin Vaccine is an oral vaccine developed by Dr. Albert Sabin to protect against poliomyelitis, commonly known as polio. It contains weakened forms of the poliovirus, which stimulate the immune system to produce antibodies without causing the disease. This vaccine is easy to administer and has been instrumental in global efforts to eradicate polio. Introduced in the early 1960s, the Sabin Vaccine replaced the earlier Salk Vaccine, which is injected. The oral form allows for mass immunization campaigns, making it more accessible in developing countries. Its widespread use has significantly reduced polio cases worldwide, contributing to the near-eradication of the disease.
