In 1967–1968 she served as Senior Associate Professor (Docent) at the Department of Geology and Palaeontology of Jan Amos Comenius University, Bratislava.
The primary emphasis of Scheibner's work in Australia with the NSW Department of Mines was the study of the Cretaceous and Permian Foraminifera of the Great Australian Basin in New South Wales.
From 1972 to 1976 Scheibner was invited to participate in the Deep Sea Drilling Project (DSDP) conducted under the auspices of the Scripps Institution of Oceanography, in the Atlantic and Indian Oceans.
However data shows that since she began making her claims, vaccination rates for Birth to 2-years component of the Immunisation Schedule in Australia increased from 53% in 1990 to 92% in 2006,[7][8] while SIDS deaths fell by 81% over the same period.
However, Victorian medical practitioner Stephen Basser, writing in the Australian Skeptic magazine, said that the studies Scheibner cited did not support her statements and that she had omitted information [from the studies] which did not support her position, including data showing pertussis mortality in Japan increased 800% in the five years following the pause in Pertussis vaccination.
Commissioner William Carter, Q.C., who was hearing a Human Rights and Equal Opportunity Commission enquiry in which Viera Scheibner was called as a witness, dismissed her claims on the subject of vaccines, finding that he was unsatisfied with her formal qualifications and professional experience, which he found did not "properly equip her to provide a valid professional opinion on the complex subject of immunology".
