  • HPV vaccinum programmes round the world are presently being evaluated.
  • proof from these shows falling numbers of teenagers with pre-cancerous cells (the cells which will proceed to cause cervical cancer) and protection from the HPV vaccine is anticipated to be long-run.
  • Gardasil is a HPV vaccine currently being used in USA and more recently, the Govt in UK have recently announced that they are replacing "CERVARIX" with "GARDASIL"

Why they are switching to GARDASIL?

  • Gardasil targets 4 strains of HPV of type 6,11,16,18 whereas Cervarix targets only 2 strains.
  • The result of extra protection and comparing the costs and benefits of both the vaccines, UK authorities decided to switch to Gardasil.
  • For the years , Gardasil has been tested extensively for the safety concern and effectiveness. And it is found to be pretty effective so far on this.
  • The complication rate is very low and minor problems are found like irritation at the point of intervention and fainting after.
  • Though, Gardasil is found to be pretty effective HPV vaccine so far, it draws criticism also.
  • Some girls(140Nos) in Ireland in 2015 suffered severe non-specific reaction to the vaccination.
  • Although, these HPVs goes away on its own, certain strains may develop into something serious.
