It has been found in a recent study that in many cases bacteria tend to prevent the efforts of a vaccine through swapping some of the quantity of their genomes with other bacteria. The findings of the study have been published in the Nature Genetics.

It has been found that this particular and peculiar nature of bacteria is carried by the diseases which are caused by Streptococcus pneumonia. It is estimated that the diseases caused by the Streptococcus pneumonia takes toll over the life of about millions of young children.

For the study, the researchers observed as to how the pneumococcus bacteria react when introduced with pneumococcus vaccine. The vaccine was introduced in the US in 2000. Following the findings of the study, the doctors noted that the evasion property of the bacteria would make it hard to treat the diseases.

Vaccination works by making the immune system stronger to fight the harmful bacteria. Dr. Rory Bowden from Oxford University said, “There are plenty of vaccines out there that look stable and continue to work because they target bacteria or viruses that are not changing”.

It has been informed that pneumococcus bacteria is found in many variants, which means that each and every variants are needed to be treated by different set of vaccines. It is estimated that all over the world about 800,000 children are affected with the diseases caused by the pneumococcus bacteria.

As it is hard to provide individual treatment for independent type of bacteria, in 2000 the US came up with one single vaccination to treat majority of the variants. Still, there were some bacteria which were capable of finding a loophole to escape from the effects of the vaccine.
