What is WI-38 in vaccines?
The WI-38 cell line is used as a culture to grow live viruses that are used in vaccines. “Merck, as well as other vaccine manufacturers, uses two well-established human cell lines to grow the virus for selected vaccines,” Merck said in a statement to ABC News.
Is MMR and MMRV the same?
Two vaccines containing measles, mumps, and rubella virus are licensed for use in the United States. M-M-R II® is a combination measles, mumps, and rubella (MMR) vaccine. ProQuad® is a combination measles, mumps, rubella, and varicella (MMRV) vaccine.

What is the WI-38 cell line?
The WI-38 cell line is the first human diploid cell line to be used in human vaccine preparation. WI-38 cells are isolated from the lung tissue of a 3-month-old, female, embryo. They can be used as a transfection host and in viruscide testing.
Where does WI-38 come from?
WI-38 is a diploid human cell line composed of fibroblasts derived from lung tissue of a 3-month-gestation female fetus. The fetus came from the elective abortion of a Swedish woman in 1962, and was used without her knowledge or permission.
How effective is the MMRV vaccine?
One dose of MMR vaccine is 93% effective against measles, 78% effective against mumps, and 97% effective against rubella. Two doses of MMR vaccine are 97% effective against measles and 88% effective against mumps.
