Polio is also called infantile paralysis is an infectious disease caused by polio virus and now it has a plant based vaccines as per the scientists and they have also revealed that plant based vaccines help to eradicate polio virus in a faster and better way.  In an experiment scientists have used plants to produce a new vaccine against the polio virus, a finding which can pave the way for global eradication of the disease. The novel vaccine was produced with a method that uses virus-like particles (VLPs) non-pathogenic mimics of the polio virus which are grown in plants. Genes that are believed to carry information to produce VLPs are infiltrated into the plant tissues. The host plant then reproduces large quantities of them using its own protein expression mechanisms.

“This is an incredible collaboration involving plant science, animal virology and structural biology. The question now arises is how to scale it up we don’t want to stop at a lab technique,” said George Lomonossoff, Professor from the John Innes Centre — a UK-based independent research organisation. VLPs look like viruses but are non-infectious. They have been biologically engineered so they do not contain the nucleic acid that allows viruses to replicate. This means that they mimic the behaviour of the virus, stimulating the immune system to respond without causing an infection of poliomyelitis, the researchers said.

Laboratory tests demonstrated that the polio virus mimics provided animals with immunity from the disease paving the way for human vaccines to be produced by plants on a major scale with the input of pharmaceutical industry collaborators. Polio virus destroys motor neurons in the central nervous system causing paralysis or even death. The Global Polio Eradication Initiative led by the World Health Organisation has resulted in 99 per cent fewer cases in the past 30 years. However, the current vaccines require the production of huge quantities of live polio virus, which increases the risk of accidental re-introductions. The successful development of VLPs not only holds promise for the production of vaccines for polio but it could also become a frontline diagnostic resource in producing vaccines against other viral outbreaks, the researchers said.
