Medical experts will be watching closely Monday when a scientist who says she has been intermittently paralyzed by a virus  designed at the Pfizer laboratory where she worked in Groton  opens a much anticipated trial that could raise questions about safety practices in the dynamic field of genetic engineering.
Organizations involved in workplace safety and responsible genetic research already have seized on the federal lawsuit by molecular biologist Becky McClain as an example of what they claim is evidence that risks caused by cutting-edge genetic manipulation have outstripped more slowly evolving government regulation of laboratories.

McClain, of Deep River, suspects she was inadvertently exposed, through work by a former Pfizer colleague in 2002 or 2003, to an engineered form of the lentivirus, a virus similar to the one that can lead to acquired immune deficiency syndrome , or AIDS. Medical experts working for McClain believe the virus has affected the way her body channels potassium , leading to a condition that causes complete paralysis as many as 12 times a month.
“If a worker in a plant as sophisticated as Pfizer is becoming infected with a genetically engineered virus, then I think the potential is everywhere,” said Jeremy Gruber, president of the Council for Responsible Genetics , a public interest group created to explore the implications of genetic technologies.
