Step 1: Understanding polio disease.
Polio is caused by poliovirus and affects the nervous system, leading to paralysis. Vaccination is essential for prevention.
Step 2: Types of polio vaccines.
There are two main vaccines: Salk (inactivated) and Sabin (oral attenuated vaccine).
Step 3: Salk vaccine characteristics.
Salk vaccine is an inactivated polio vaccine (IPV) developed by Jonas Salk. It is injected and provides immunity.
Step 4: Evaluation of other options.
BCG is for tuberculosis, DPT is for diphtheria-pertussis-tetanus, and HPP is unrelated.
Step 5: Importance of vaccination.
Salk vaccine helps in developing immunity without causing disease.
Step 6: Final conclusion.
Thus, polio vaccine is also called Salk’s vaccine.
