When did they stop giving polio vaccine in Canada?
Disease distribution 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..
Does polio vaccine last a lifetime?
The polio vaccine provides lifelong immunity and is the only means of polio prevention. There are two types currently available: the oral polio vaccine (OPV) and the inactivated polio vaccine (IPV). The vaccine results in humoral (circulating antibody) and mucosal (secretory immunoglobulin A) immune responses (27).
Do we still vaccinate for polio in Canada?
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.
What are the risks of polio vaccine?
IPV has not been known to cause serious problems, and most people don’t have any problems at all with it. However, any medicine could cause a serious side effect, such as a severe allergic reaction or even death. The risk of polio vaccine causing serious harm is extremely small.
Do adults need 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.
How long did it take to get a vaccine for polio?
Researchers began working on a polio vaccine in the 1930s, but early attempts were unsuccessful. An effective vaccine didn’t come around until 1953, when Jonas Salk introduced his inactivated polio vaccine (IPV).
What is the age limit for polio vaccine?

How did people get polio?
The polio virus usually enters the environment in the feces of someone who is infected. In areas with poor sanitation, the virus easily spreads from feces into the water supply, or, by touch, into food. In addition, because polio is so contagious, direct contact with a person infected with the virus can cause polio.
When did Canada start vaccinating for polio?
The widespread application of the Salk vaccine (introduced in 1955) and the Sabin oral vaccine (introduced in 1962) eventually brought polio under control in the early 1970s. Canada was certified “polio free” in 1994.
Do we still get polio vaccines?
The inactivated polio vaccine (or IPV) is now the only vaccine given in the United States to prevent polio. IPV is given as a series of four shots at 2 months, 4 months, 6 to 18 months, and again at 4 to 6 years of age.
Is polio vaccine still given in Australia?
Immunisation against polio Immunisation is the best protection against polio and is recommended for all infants, children and adults. In November 2005, an inactivated polio vaccine (IPV) replaced the oral vaccine in Australia.
