When did Canada stop vaccinating for polio?
The incidence of polio in Canada was dramatically reduced by the introduction of immunization programs in the 1950s.
In Canada, after using the live attenuated oral polio vaccine (OPV) for many years, its use was replaced with an inactivated poliomyelitis vaccine (IPV) in 1995/1996..
Should adults get a polio booster?
Routine poliovirus vaccination of U.S. adults (i.e., persons aged >18 years) is not necessary. Most adults do not need polio vaccine because they were already vaccinated as children and their risk of exposure to polioviruses in the United States is minimal.
Is it OK to have polio vaccine twice?
There is no risk of overdose, fully immunized children receiving extra doses of OPV will receive extra protection against polio. The vaccine is administered multiple times to ensure full protection. There is minimal risk of adverse effects from OPV.
What caused polio outbreak in the 50’s?
No one knew how polio was transmitted or what caused it. There were wild theories that the virus spread from imported bananas or stray cats. There was no known cure or vaccine. For the next four decades, swimming pools and movie theaters closed during polio season for fear of this invisible enemy.
What is the age limit for polio vaccine?

Do polio vaccines expire?
The last dose in either series should be given after 4 years of age and at least 6 months after the previous dose.
How long did they test the polio vaccine?
The 1954 field trials that followed, the largest in U.S. history at the time, were led by Salk’s former University of Michigan colleague, Dr. Thomas Francis, Jr. In the late 1950s, Polish-born physician and virologist Albert Sabin (1906-1993) tested an oral polio vaccine (OPV) he had created from a weakened live virus.
Does Canada still vaccinate for polio?
Vaccine programs in Canada switched from OPV to IPV in 1995/1996. OPV is no longer recommended or available in Canada because most cases of paralytic polio from 1980 to 1995 were associated with OPV vaccine. OPV vaccine continues to be widely used internationally.
Can you still get polio if vaccinated?
No, thanks to a successful vaccination program, the United States has been polio-free for more than 30 years, but the disease still occurs in other parts of the world. It would only take one person with polio traveling from another country to bring polio back to the United States.
