What do we know about the COVID-19 (coronavirus) vaccine?

Unchallenged

Some COVID-19 vaccines are being developed using cells originally isolated from foetal tissue (often referred to as foetal cells).

The foetal cells being used are derived from two sources (HEK-293 and PER.C6). HEK-293 is a kidney cell line that was isolated from a terminated foetus in 1972. PER.C6 is a retinal cell line that was isolated from a terminated foetus in 1985.
