Rubella is a serious viral decease, which can deeply harm an unborn child, if and infection of the mother takes place during the first trimester of her pregnancy. To prevent such a situation a number of vaccines were developed, and their use practically eliminated this decease in the USA. The problem is, that those vaccines were developed basing on WI-38 and MRC-5 cell-lines, provided from the directly aborted human embryos. In June 2003 a pro-life organization “Children of God for Life” sent a letter to cardinal J. Ratzinger with the question on morality of the use of questioned substances. In provided two years later response of the Papal Academy “Pro Vita”, a conditional affirmation was given. The article discusses arguments on the topic, questioning also some of them.
