Every year on March 26, we commemorate how science has benefitted us and acknowledge the advancement of science around the world.
On March 26, Jonas Salk, the developer of the polio vaccine, declared the first success of the polio vaccine.
Polio vaccine is a vaccine to prevent diseases caused by poliovirus, which can be fatal to children.
There are two types of polio vaccine:
Inactivated poliovirus vaccine (IPV) : given by shots
Oral poliovirus vaccine (OPV) : given by drops
So how effective is the vaccine?
According to the CDC, all of the recommended doses showed practically full protection against diseases caused by poliovirus, whereas two doses of IPV provide at least 90% protection and three doses provide at least 99%. [1]
