A Christian response to COVID-vaccine doubts

Paul Ewart and Mirjam Schilling

As Christians we express our love for God by showing love to our neighbour and, as Christ taught us in his famous parable of the Good Samaritan, “our neighbour” means anyone we meet, irrespective of their relationship to us. Clearly, loving our neighbour includes not putting them at risk of harm, and we are being told that an important way of protecting those in our community, as well as ourselves, during the current Coronavirus pandemic, is to be vaccinated. Three questions have, however, been circulating that seem to undermine this advice. Is it real? Is it safe? Is it right?

The first question doubts the reality of the pandemic by suggesting that either the pandemic is a hoax or there is a conspiracy to inject the world’s population with some kind of microscopic tracking device in order to control people. Such bizarre ideas spreading on social media, entirely without evidence or rational foundation, are readily debunked by going to trusted and competent advisors. In any case, most of us know the reality of Covid, having had a relative or friend affected by the disease. As Christians we have a responsibility to seek and tell the truth.

The second questions the safety of the vaccine by raising concerns about the speed of its development and possible side-effects. The fact that effective vaccines have been developed within one year of the appearance of the coronavirus is indeed remarkable, but the work did not begin just when this virus was first detected in December 2019. Scientists have been studying viruses and how to produce vaccines for many years and the basic technologies had already been developed so that researchers were ready to apply them once the nature of the coronavirus was analysed. Nonetheless, the scientists, medics and others who produced the vaccines and ensured they were tested properly have done a remarkable job and deserve our thanks and praise for their dedication and hard work. It has also been a cause of thanksgiving that the vaccines have been proven to be remarkably free of adverse side-effects. As vaccines are meant to teach our immune system about a real infection, the aim is to stimulate the immune system to recognise and respond to the Covid virus. This can cause, for some people, a few mild symptoms that for many will go unnoticed and, only extremely rarely, people who are highly allergic (and therefore have an alerted immune system) might have more severe symptoms. No medication can ever be completely 100% free of risk since humanity is so diverse and rare reactions can happen. The key, however, is in understanding the relative risk compared both to other risks we take every day and compared to the benefits to ourselves and others. It is not 100% safe to travel by air or in a car and yet most of us take such risks without much thought. We take medicines such as paracetamol or aspirin in spite of the fact that there is a very small risk to our health by taking them. The COVID-19 vaccines have been found to be safe in the same way as other vaccinations and health treatments and protect from the much bigger risk of a real infection with the virus. Therefore, anyone who is worried can be reassured that it is safe to be vaccinated. If anyone is concerned about a specific precondition that they have, their GP will be able to advise them on their personal risk.

The third question – is it right? – is more complicated and involves our individual conscience. The problem has been raised by claims that the development of the vaccines involved the use of tissue from an aborted human embryo, in either the production or the testing. How should a Christian, or anyone concerned about the morality of abortion, decide whether or not to use something derived from a morally debatable action? It is important, first, to be clear about some facts. No tissue from embryos is used in the production of any of the current vaccines. What happened was that some tissue from a single embryo, aborted for unknown reasons, over 50 years ago was used to create a “cell line”. This process creates a source of new, but not entirely identical, cells that can go on replicating almost indefinitely. All biomedical research depends on cell lines that mimic the biological reality in our own cells. Most of these cell lines were made from cancer cells that originate from real patients, only very few cell lines were once made from an aborted embryo. Nevertheless, all of these cell lines still are an extremely valuable and indispensable resource. Most medicines, vaccines and even potential cures for cancer could not have been developed without such cell lines. The question is therefore, is it morally acceptable to benefit from an act that one may believe to have been immoral? The abortion issue is complex and Christians, in good conscience, can take different and opposing views. For those who are willing to approve abortion in some circumstances, such as to save the life of the woman bearing the embryo, then using some of the tissue to achieve a good end, may be entirely acceptable.  Others, who believe all abortions are immoral, face a more complex decision. In some ways the problem may be a choice of the lesser of two evils. In other ways, it involves deciding to what extent we can isolate ourselves from the world which engages in all sorts of immorality. Should we, for example, object to the use of chemotherapy to treat cancer because its effects were discovered from the use of poison gas developed to kill people? Would it be right to deny the treatment to a loved one or any other “neighbour” because of how it was obtained? It must surely be the loving thing to do to bring good out of a particular circumstance without, in general, using the end to justify the means.

No two moral issues are identical and the issue for Christians concerned about the abortion issue, in respect of the vaccine, is how to decide between two principles. The first is Christ’s call to love and protect “our neighbour” and the second is to respect life in all its stages of development. We cannot change the past nor completely isolate ourselves from a world of people so affected by sin. We can, however, choose the better outcome for those for whom we are now responsible – the vulnerable elderly, those with underlying health conditions and others most at risk from COVID-19. This directs us to encourage Christians to take the vaccine for the greater good. Ultimately, however, the choice is a matter for our individual conscience before God, let us pray that we make the right choice.

Nominations for the Christians in Science Oliver Barclay Lecture 2021


Nominations are open –

Christians in Science sponsors an annual “Oliver Barclay Lecture” in memory of Dr Oliver Barclay who was the driving force behind the establishment of The Research Scientists Christian Fellowship, the predecessor of CiS, and who was keen to encourage the next generation of effective communicators on Science and Faith.

The lecture is awarded to a promising young individual, usually under the age of 35, who has demonstrated an ability to communicate effectively on issues relating to Science and Faith. The chosen individual, who will normally be an active UK-based scientist, will present a short lecture on the topic of their choice at the annual Southern (Autumn) Conference. We hope they will also present their lecture the following year, at the Student and Northern (Spring) Conferences. He/she will receive travel expenses for each conference they give the lecture, and one honorarium equivalent in value to that given to other established conference speakers.

Additionally, if you would like to be considered for this lectureship, please contact [email protected] to discuss further.

CiS members are invited to nominate for the annual award with a closing date of midnight 31st March 2021

Nomination Criteria

  1. Prior to submission, the nominator should ensure that the nominee is available to attend the CiS Southern Conference (usually during October or early in November). If circumstances prevent a “face to face” conference, the lecture will be precorded similar to 2020 conference.
  2. The nominator must also ensure that 2 referees will send an assessment of the candidate’s suitability for the award by 14th April.
  3. Nominations should be sent to the Executive Officer together with :-
    • an up to date curriculum vitae of the nominee
    • details of the two referees
    • and an 5 min video of the nominee, speaking on a topic of the nominee’s choice.

Nominations will be considered in April by a selection committee appointed by the CiS Executive Committee, and a recommendation made to the Trustees.

Nominations, and any further questions, should be sent to Mary, CiS Executive Officer ([email protected])

Thoughts from Prof Paul Ewart, CiS Chair, on Science, Christ and Corona virus

Einstein’s scientific theories are famously difficult to understand for most people and he is quoted as saying that explanations should be “as simple as possible … but no simpler.” Simple explanations are hugely attractive and simplicity is often seen as a characteristic of a theory’s validity. And yet, Einstein’s warning is also valid, for when an explanation becomes too simple, as it may, then it can cease to be an explanation at all.

Theological theories are no less prone to the dangers of over simplification and when they mutate into doctrines then they risk becoming unhelpful. The current pandemic of Covid-19 caused by the corona virus can be explained scientifically but it is also raising theological questions. Questions like, “Why is this happening?” or “Where is God in this disaster?” are receiving public explanations from respected Christian leaders and apologists.

I fear, however, that some of these are just too simple and raise more questions than they answer. Of course, such questions are neither new nor specific to the corona virus. The “standard” answer being given – that we live in a “fallen world”, is also not new, but I believe it needs to be re-examined in the light of Scripture and the teaching of Christ.

The idea of “the fall”, as is well-known, is based mostly on the first three chapters of Genesis and an enigmatic passage in Romans chapter 8, where Paul speaks of Creation being subject to futility and, in the context of hope of future glory, its being “set free from its bondage to decay.” (Romans 8:21)

The Genesis message is of a world made “good” by its Creator and yet now, in our experience of natural disasters or a pandemic, it looks far from good. The simple conclusion is that a world that was once perfect has been spoiled as a result of human sin – the curse put upon the ground by God following Adam’s disobedience. The explanation is thus that suffering, including the present pandemic, is God’s response to human sin. “Simples” as Orlov the meerkat would say!

Following St Augustine, the Christian church has gradually taken this idea to be a basic doctrine rather than just a theological theory. But is it really biblical? How does it fit with the rest of the Bible and, more importantly, with what Christ says about human suffering? The truth is that there is very little else in the Old Testament, the Hebrew Scriptures, to support the idea and it has no place in Jewish theology.

The book of Job is pretty clear that poor Job did not suffer because of his sin. Nonetheless the idea persisted that human suffering from such things as congenital blindness (John 9:1,2) or being killed by a collapsing tower (Luke 13:4) are divine punishment. And yet, Jesus explicitly rejects this simple explanation. Things are more complicated and more subtle than that. Jesus tells us that these things are opportunities to experience the grace of God’s work in our lives. (John 9:3)

We are not given tidy explanations of why the world is the way it is.

Genesis teaches us that the world was made good, and good in the sense of being fit for purpose rather than perfect as we might understand perfection. The whole of the Bible is surely an account of how men and women experience God’s grace in the ups and downs of life, its pain as well as its joys. It is by finding the grace of God in an uncertain world that faith grows to maturity. Job was given no simple answer to his question, “Why is this happening to me?” Instead of reasons he finds a relationship with his Creator and vindication of his faith that his redeemer lives and that in his flesh he shall see God. (Job 19:26)

This pandemic, like so many things in life, presents us with a puzzle, but we are reassured by Paul that, “For now we see in a mirror, dimly, [or in a riddle] but then we will see face to face. Now I know only in part; then I will know fully, even as I have been fully known.” (1 Corinthians 13:12). Christ, above all, teaches us that our faith is not a matter of knowing what we cannot understand; it is, instead, trust in a loving God who will make all things well. Our task is to work in the suffering world using God’s gift of science and show the love of Christ to all.
