Salk vaccine

The Salk vaccine, developed by Jonas Salk in the 1950s, is a safe and effective injectable vaccine that protects against poliovirus, which can cause paralysis. It contains inactivated (killed) virus particles, prompting the immune system to recognize and defend against future infections without causing illness. The vaccine stimulates the body to produce immunity, helping prevent the spread of polio in the community. It has been a vital tool in reducing and nearly eradicating polio worldwide, contributing significantly to public health efforts against this serious disease.
