A new vaccine of polio has been introduced. It has been reported that this is more effective than the current one.  It can reduce the disease caused by polio virus by 90%. The research was published in an online journal named The Lancet. It shows that the new vaccine can protect the children from polio more effectively than the current popular vaccine. 

It has been reported that new polio vaccine has already been used in India, Afghanistan and Nigeria. The scientists behind the discovery of this new vaccine believe that it could eradicate the disease more skillfully. 

Mass vaccination campaign has been organized in different parts of the world. The result was very satisfactory. The number of polio endemic countries has been reduced from 125 in 1988 to only four in 2005. Thus it means that an actual drop in cases from 350,000 to just 1,606 in 2009. 

Polio is mainly caused by one of the three versions of the polio virus. They are type 1, type 2 and type 3.  Recently vaccines that could immunize either all three forms of virus or just one of them were used. 

The new vaccine has been tried out by the author of the study. This new version has to be taken orally. Blood samples were taken before vaccination and after the first and the second doses to measure seroconversion. By seroconversion we mean the rise in the number of antibodies which is produced by the immune system against polio. 

It has been found that the result is 30% more effective than the vaccine that has been used till date.
