paragraph_text: Contraception
  
  The church teaches that sexual intercourse should only take place between a man and woman who are married to each other, and should be without the use of birth control or contraception. In his encyclical Humanae vitae (1968), Pope Paul VI firmly rejected all contraception, thus contradicting dissenters in the church that saw the birth control pill as an ethically justifiable method of contraception, though he permitted the regulation of births by means of natural family planning. This teaching was continued especially by John Paul II in his encyclical Evangelium Vitae, where he clarified the church's position on contraception, abortion and euthanasia by condemning them as part of a "culture of death" and calling instead for a " culture of life ".
  
  Many Western Catholics have voiced significant disagreement with the church's teaching on contraception. Overturning the church's teaching on this point features high on progressive agendas. Catholics for Choice, a political lobbyist group that is not associated with the Catholic Church, stated in 1998 that 96% of U.S. Catholic women had used contraceptives at some point in their lives and that 72% of Catholics believed that one could be a good Catholic without obeying the church's teaching on birth control. Use of natural family planning methods among United States Catholics purportedly is low, although the number cannot be known with certainty. As Catholic health providers are among the largest providers of services to patients with HIV/AIDS worldwide, there is significant controversy within and outside the church regarding the use of condoms as a means of limiting new infections, as condom use ordinarily constitutes prohibited contraceptive use.
  
  Similarly, the Catholic Church opposes artificial insemination regardless of whether it is homologous (from the husband) or heterologous (from a donor) and in vitro fertilization (IVF), saying that the artificial process replaces the love and conjugal act between a husband and wife. In addition, it opposes IVF because it might cause disposal of embryos; Catholics believe an embryo is an individual with a soul who must be treated as such. For this reason, the church also opposes abortion.
  
  Due to the anti-abortion stance, some Catholics oppose receiving vaccines derived from fetal cells obtained via abortion. On 21 December 2020, and regarding COVID-19 vaccination, the Congregation for the Doctrine of the Faith emitted a document stating that "it is morally acceptable to receive Covid-19 vaccines that have used cell lines from aborted fetuses in their research and production process" when no alternative vaccine is available, since "the moral duty to avoid such passive material cooperation is not obligatory if there is a grave danger, such as the otherwise uncontainable spread of a serious pathological agent." The document states that receiving the vaccine does not constitute endorsement of the practice of abortion, and that "the morality of vaccination depends not only on the duty to protect one's own health, but also on the duty to pursue the common good." The document cautions further:
  
  Those who, however, for reasons of conscience, refuse vaccines produced with cell lines from aborted fetuses, must do their utmost to avoid, by other prophylactic means and appropriate behavior, becoming vehicles for the transmission of the infectious agent. In particular, they must avoid any risk to the health of those who cannot be vaccinated for medical or other reasons, and who are the most vulnerable.
