Ultraviolet B Exposure Has No Bearing On Hepatitis B Vaccine Effectiveness.(Brief Article)
2001 DEC 12 - (NewsRx.com & NewsRx.net) -- by Sonia Nichols, senior medical writer - Ultraviolet radiation exposure, known to suppress immune system response, does not affect the body's response to hepatitis B virus (HBV) vaccine.
It does however, affect other avenues of immune system response, the authors of a Netherlands study report.
Scientists say ultraviolet radiation exposure causes immune system suppression within the body as well as on the surface of the skin. Since the immune system responds to vaccination in a manner similar to that seen following infection, A. Sleijffers and colleagues, University Medical Center Utrecht, administered HBV vaccines to several study volunteers in order to gain a better understanding of radiation's effects following encroachment by bacterial or virus-like particles.
Approximately half of the 191 volunteers were exposed to UVB radiation for five consecutive days prior to receiving the first dose of HBV vaccine. Blood testing performed before and after radiation exposure and HBV inoculation suggested the immune systems in the volunteers responded normally in terms of stimulating cellular immune response and generating HBV ...
