Re: "Logical correlation" and scientific Double Standard

Yet it is still logical. Just like the vaccine manufacturers , state that HPV vaccines "prevent cancer" yet they have no long term studies that test the hypothesis they state as fact.

-------------------------------------------------

Writing in JAMA, the team led by Dr Maura Gillison, said their findings should influence research into the existing HPV vaccines and how effective they could be in preventing oral cancers.

"Vaccine efficacy against oral HPV infection is unknown, and therefore vaccination cannot currently be recommended for the primary prevention of oropharyngeal cancer.

"Given an analysis of US cancer registry data recently projected that the number of HPV-positive oropharyngeal cancers diagnosed each year will surpass that of invasive cervical cancers by the year 2020, perhaps such vaccine trials are warranted."

Jessica Harris, health information manager at Cancer Research UK, said: "As we learn how common HPV infections in the mouth are, and how they are passed on, we can understand more about who is most at risk and how people can reduce the risk of HPV-related cancers.

"Although there isn't yet any evidence to show whether HPV vaccination is effective at preventing oral HPV infections, results like these are vital to help inform prevention programmes in the future."

Logic is valid. All by itself. It makes sense. Otherwise it is not logical.
