Polio is an extremely contagious viral infection of the gut. Following infection some people will develop variable degrees of paralysis which may result in permanent disability or death.
Polio was very common in Australia until around 1960 when immunisation dramatically reduced its incidence – however it is still common in some countries. Until recently vaccination was by live polio virus - this has now been replaced for childhood immunisation with the inactive IPV vaccine which is incorporated within the triple antigen vaccine and does not have the potential issues associated with the live virus - Triple Antigen IPV. Previously, and for those not eligible for Triple Antigen IPV or IPV vaccine an oral polio vaccine is, or, was used. The Vaccine: An inactive vaccine (IPV) which is incorporated within the triple antigen vaccine (Triple Antigen IPV) and does not have the potential issues associated with the live virus of the old oral drops vaccine mentioned above.
Please refer to the Triple Antigen IPV vaccination for further details. Recommended for:It is recommended that children are vaccinated via the Immunisation Schedule for Children
Now the IPV is given with the Triple Antigen IPV vaccination. Please refer to that vaccination for further details. Adverse Reactions:Reactions to the old vaccine OPV were more common being that it was a live vaccine.
Now the IPV is given with the Triple Antigen IPV vaccination. Please refer to that vaccination for further details. |
OLD POLIO VACCINE
Unlike most vaccines, oral polio vaccine (OPV) is a live vaccine. The usual course is given as 2 drops of OPV medicine at 2,4 and 6 months with a booster at 4 years. Reactions to oral polio vaccine are uncommon, but precautions need to be taken because live virus is excreted in the child’s stool for approximately 6 weeks after each dose – an infection could be picked up by susceptible people from the faeces. Because the live vaccine virus is excreted in faeces for 6 weeks, carers should be very careful with hygiene, particularly when changing nappies - which should be safely disposed of. Very rarely (there have been 2 cases in Australia in the past 13 years) the vaccine can cause a form of paralytic polio in the person receiving it – vaccine associated paralytic poliomyelitis (VAPP). The following people should not be vaccinated with oral polio vaccine (OPV)
An alternate to oral polio is available – a non live vaccine (IPV), given by injection and this IPV alternative can be used in the **above instances. |
