Efficacy of any vaccine depends on its capability ot successful eliciting or exhibiting antigenicity without causing actual disease or infection, by incorporating strains and genetic material and isolated viral proteins of the infectious bacteria or virus.
Incase the vaccine misses out to include any virulant strain of existing pathogen, vaccine will not work against that perticular pathogen, or may exerst lower immunogenicity.
The present Corona Virus stain found in UK is reported to be a mutant and is more virulant.
So it’s important to assess if the vaccines made Globally does consist that strains so that the vaccine is effective for all mutants and strains.
Inorder to make use of the mutants protein and genetic material in vaccine it is required that the virus strain is isolated as pure culture in laboratory.
India’s National Institute of Virulogy situated at Pune India which is center of Indian Council for Medical Research (ICMR ) has announced that they have successfully Isolated the mutant SARS-COV-2 viral strain which is found in UK.
This is one of great achievement for the scintific community working on vaccine development.
