Between September 2012 and August 2013 The experts interviewed 124 parents and 37 health-care companies at four clinics. Parents and providers were asked to discuss their reasons why their HPV vaccine eligible girls did or did not ultimately have the vaccine. Remarkably, the most typical parental cause was that their child was never offered the vaccine. Other common reasons included the perception that the vaccination was optional rather than recommended or being told by their company that it was unnecessary prior to sexual debut. Among those that declined the vaccine, the rationale often involved safety issues and a belief that their daughters were too young to need it.The Linus Pauling Institute in Oregon notes: ‘. Multiple studies have found that the combination of vitamin C and supplement E protects the skin against UV damage. Human subjects orally co-supplemented with vitamins C and E present increased Minimal Erythemal Dose , a way of measuring photoprotection from UV light in pores and skin. The combination of the two vitamins was associated with lower amounts of DNA damage after UV exposure. Results of another scholarly research suggest a mixture of tocopherols and tocotrienols could be superior to alpha-tocopherol alone, as the combination showed decreased sunburn reactions and tumor incidence after UV exposure in mice.’..
