New Human Fetal Cell Lines Available for Vaccine Production

Human cells from the tissue of aborted fetuses have been used in vaccines since the 1960s, and currently they are used in 11 vaccines. Aborted human fetal cell cultures are used for growing viruses, which are then used in the preparation of inactivated and live virus vaccines. They may also be grown on chick embryos or cells from different animals and bugs, such as army worms. 

A study published in 2015 in the journal Human Vaccines & Immunotherapeutics confirms that in addition to the two primary cell cultures that have been used for more than half a century to make hundreds of millions of doses, a third aborted human fetal cell culture may be used. Called Walvax-2, it has been assessed as a culture for growing rabies, hepatitis, and varicella viruses. 

Source tissue for this new cell line was obtained from nine fetuses provided by the Department of Obstetrics and Gynecology of Yunnan Hospital in China. Relatively little additional information about Walvax-2 is available from public sources. It is not clear how the name was derived, what government agency or company is leading the research, or the possible application of the cell line to vaccine production.

Listen to Theresa Deischer, PhD talk about how humans and their parts can be exploited for medical manufacturing and product commodities in The Commoditization of Human Beings.
