The Infected Blood Scandal and Inquiry Explained: Lessons for Medicine Interviews

The infected blood scandal was the NHS treatment disaster in which more than 3,000 people died after being given blood or blood products contaminated with HIV and hepatitis, mainly from the 1970s to the early 1990s. For medicine interviews, it’s a key case study in informed consent, candour and listening to patients.

I’m Dr Akash Gandhi, an NHS GP and the founder of TheUKCATPeople, and I’ve been helping students prepare for medicine interviews since 2012. This scandal is still painful for thousands of families, and this guide sits alongside our wider NHS hot topics guide.

What was the infected blood scandal?

The infected blood scandal was the infection of tens of thousands of NHS patients with HIV, hepatitis C and hepatitis B through contaminated blood transfusions and blood products. The public inquiry into it quoted Lord Winston’s description of the events as the worst treatment disaster in the history of the NHS.

• Who was harmed: people with bleeding disorders such as haemophilia, and people given blood transfusions, for example during childbirth or surgery
• The infections: HIV, hepatitis C and hepatitis B, which can lead to AIDS, cirrhosis, liver failure and liver cancer
• When: mainly from the 1970s until screening of every blood donation for hepatitis C began in September 1991
• The scale: more than 3,000 deaths are attributed to infected blood, blood products and tissue
• The inquiry: the Infected Blood Inquiry, chaired by Sir Brian Langstaff, published its final report on 20 May 2024

The table below is most of what you need on the timeline.

Key Takeaway: Describe it as an NHS treatment disaster that harmed tens of thousands of patients and was largely avoidable, then move on to the lessons.

What happened between the 1970s and the early 1990s?

Patients were infected through clotting factor products given to people with bleeding disorders, and through ordinary blood transfusions. The inquiry found that both routes carried risks that were known at the time and were played down.

• Bleeding disorders: people with haemophilia lack a clotting protein, and from the 1970s many were treated with concentrates such as Factor 8, made from plasma pooled from many donors
• Bigger pools: it was well known that larger pools would markedly raise the risk of passing on a virus
• Imported products: from 1973, concentrates made in the US or Austria were licensed for use in the UK, even though they carried a high risk of hepatitis
• Transfusions: blood was collected from prisons in England and Wales until the end of 1984, and some transfusions were given when they weren’t clinically needed

Awareness of AIDS began in 1981, and the virus behind hepatitis C wasn’t identified until 1988. Even so, blood had been known to transmit hepatitis since the 1940s, and by mid 1982 it was apparent that AIDS might be spread by blood products.

Wasn’t it only obvious with hindsight?

The inquiry rejected that view. It found the disaster could largely, though not entirely, have been avoided, and criticised waiting for conclusive proof that blood caused AIDS instead of asking whether there was a real risk.

Key Takeaway: The risks were known or knowable, and the inquiry found that waiting for certainty instead of acting on a real risk cost lives.

How many people were infected and how many died?

The inquiry’s most accurate estimate is that more than 3,000 deaths are attributable to infected blood, blood products and tissue. The figures below come from the summary of the final report, and each one stands for a person and a family.

• HIV in people with bleeding disorders: around 1,250 people, including about 380 children, and three quarters of them have died
• HIV through transfusions: between 80 and about 100 people, of whom about 85 per cent have died
• Hepatitis C through transfusions: around 26,800 people between 1970 and 1991, of whom about 22,000 had a chronic infection
• Hepatitis C in people with bleeding disorders: between 2,400 and 5,000 people who were infected with hepatitis C without HIV
• Hepatitis B: the inquiry couldn’t estimate the numbers, because the data were too limited

When I teach this topic, I ask students to picture a boy with haemophilia at school in the 1980s, given treatment his family trusted. Keeping him in mind helps you talk about the numbers with respect.

Key Takeaway: Know the headline figure of more than 3,000 deaths, and talk about the people affected before you talk about the numbers.

What did the Infected Blood Inquiry find?

The inquiry found that the disaster could largely have been avoided, that patients were kept in the dark about risks, tests and diagnoses, and that the truth was hidden for decades. The Infected Blood Inquiry report describes a catalogue of failures that, taken together, amounted to a calamity.

• Treatment without informed consent: patients weren’t told the risks of factor concentrates or transfusions, or about safer alternatives
• Research without consent: some patients, including pupils at Treloar’s, a school with its own haemophilia centre, were treated as objects for research without them or their parents being told
• Testing and telling: samples were tested for HIV and hepatitis without patients knowing, and some people learned they were infected months or years later
• Overriding patients’ wishes: some patients were transfused when they didn’t need it or had refused, a reminder of why refusals of blood transfusion must be respected
• Hiding the truth: officials repeated misleading lines, such as that patients had received the best treatment available, and some government files were deliberately destroyed

Asked whether there had been a cover-up, the report answered that there had been, though not a planned conspiracy: much of the truth was hidden to save face and to save expense.

Some clinicians described the 1970s and 1980s as an era of paternalism. The report found that a doctor-knows-best attitude may explain some failings but doesn’t excuse them, because respect for patient autonomy was already a basic ethical principle.

Key Takeaway: The inquiry’s core finding is that patients were harmed by their treatment and then harmed again by a system that kept the truth from them.

How did the government respond to the report?

On the day the report was published, 20 May 2024, the Prime Minister, Rishi Sunak, made a full apology in the House of Commons on behalf of the state. In his statement to Parliament, he called it a day of shame for the British state and said he was truly sorry on behalf of every government back to the 1970s.

• A promise of compensation: he committed to paying comprehensive compensation to people who were infected and people who were affected
• The recommendations: in May 2025 the government said it had accepted all 12 of the report’s recommendations, some in full and some in principle

An apology can’t undo the harm, and many families felt it came decades too late. It still matters, because acknowledgement is usually the first thing people ask for when care goes wrong.

Key Takeaway: The state apologised in full in May 2024, and the question since then has been how quickly the promised compensation reaches people.

How does infected blood compensation work, and how far has it got?

Compensation is paid by the Infected Blood Compensation Authority (IBCA), an independent body sponsored by the Cabinet Office, from £11.8 billion the government set aside in the Autumn Budget 2024. Infected people, affected family members and carers, and the estates of people who have died can all claim.

• Interim payments: £100,000 each went to infected people and bereaved partners on support schemes in October 2022, and interim payments passed £1.4 billion by April 2026
• Registration: a service for registering an intention to claim opened on 9 October 2025, and had received 20,487 registrations by 25 August 2026
• Opening up: claims opened to living infected people never compensated before in November 2025, and to affected people and estates in December 2025, as IBCA’s timeline of the scheme shows
• Progress so far: by 25 August 2026, 3,512 people had been paid, totalling more than £2.2 billion, according to IBCA’s published figures
• Changes in 2026: in April 2026 the government announced bigger awards for some groups, including an unethical research award for everyone treated for a bleeding disorder in a set period

The pace has been heavily criticised. In his additional report on compensation on 9 July 2025, Sir Brian Langstaff found the scheme had been designed without enough involvement from the people it was for, and recorded fears that victims would die before being paid.

Key Takeaway: More than £2.2 billion had been paid by August 2026, but families have waited decades and many people died before they could be compensated.

What can doctors learn from the infected blood scandal?

The biggest lesson is that patient safety must come first, and that patients have a right to know the truth about their treatment, its risks and anything that has gone wrong. The report calls safety the paramount consideration.

• Informed consent: explain the risks of a treatment or a research study and the reasonable alternatives, so the patient can choose, as our guide to informed consent explains
• Candour: be open and forthcoming when something goes wrong, even when the patient hasn’t thought to ask
• Listening to patients: families raised concerns for decades before a public inquiry was set up, which links to the thinking behind Martha’s Rule
• Protecting privacy: patients with HIV faced stigma, and records that flagged them as high risk made it worse, which is why patient confidentiality matters
• Speaking up: staff who see a risk need to feel able to raise it, as our guide to whistleblowing in the NHS covers

As a GP, I take consent every week for things like vaccinations and minor procedures. I explain the common risks and the serious ones even when they’re rare, because the patient is the one who lives with the outcome.

What is the duty of candour?

The duty of candour is the obligation to be open and honest with patients when something goes wrong with their care. It exists both in law and as a professional duty.

• Statutory duty: NHS organisations in England have had a legal duty to be open with patients since 2014, Scotland since 2018 and Wales since 2023
• Professional duty: the GMC and the Nursing and Midwifery Council expect every doctor and nurse to explain fully and promptly what has happened and its likely effects
• What the inquiry wants: the legal duty extended to individual NHS leaders such as board members, and a statutory duty introduced in Northern Ireland

The legal duty came in after the Mid Staffordshire scandal, which our guide to the Francis Report covers, and the professional duty is set out in Good Medical Practice 2024.

Key Takeaway: Informed consent, candour and listening to patients are the lessons of this scandal, and each one is part of a doctor’s duties today.

How can I talk about the infected blood scandal in my medicine interview?

Use the scandal as an example when a question touches on consent, honesty, patient safety or trust, and link it to experiences of your own, such as these.

• Work experience: a time you saw a doctor or nurse explain the risks of a procedure before going ahead
• A part-time job or volunteering: a time you had to own up to a mistake, such as getting an order wrong, and what you did to put it right

Then give your answer a clear shape:

1. Say briefly what happened and when, with one accurate fact such as the 3,000 deaths
2. Name the failing that fits the question, such as consent, candour or listening
3. Link it to a principle doctors follow today, like the duty of candour
4. Add something from your own experience
5. Finish with what you would do as a medical student or future doctor

Here’s what interviewers are usually looking for:

• Sensitivity: that you talk about victims and their families with respect
• Understanding: that you can explain the ethics in your own words, using ideas like autonomy and non-maleficence
• Reflection: that you can apply the lessons to the doctor you want to be

Do I need to memorise all the numbers?

No. One or two accurate facts, such as more than 3,000 deaths and the final report in May 2024, are plenty. Our guide to answering medical ethics questions shows how to build the rest of the answer, and our NHS interview topics guide links this scandal to other NHS stories.

When I run mock interviews on this topic, I ask students to start with the patients and end with themselves, because that keeps the answer respectful and shows you’ve applied the lessons to your own future practice.

Key Takeaway: Start with the patients, name the failing that fits the question, and end with what it means for you as a future doctor.

What interview questions could come up on the infected blood scandal?

You are unlikely to be asked any of these word for word, and you do not need a prepared answer to each one. Use them to check your understanding: if you could speak for a minute on most of them, you know this topic well enough for whatever the interviewer actually asks.

Questions to get you thinking

1. What do you know about the infected blood scandal?
2. What can doctors learn from the infected blood scandal?
3. Why is it important to be honest with patients when something goes wrong?
4. What does informed consent mean, and why does it matter?
5. Why might a patient lose trust in the NHS, and how could doctors win it back?
6. Tell me about a time you had to admit you’d made a mistake.

Harder questions to stretch you

1. Is it fair to judge doctors from the 1970s by today’s standards?
2. Is it ever right to hold back information from a patient to avoid upsetting them?
3. Should NHS managers have a personal legal duty of candour?
4. Compensation can’t undo the harm. Why does it still matter?

Model answer: "What can doctors learn from the infected blood scandal?"

The infected blood scandal happened mainly in the 1970s and 1980s, when thousands of NHS patients, many with haemophilia, were given blood products contaminated with HIV and hepatitis C. The inquiry found that more than 3,000 deaths are linked to it, and that most of the harm could have been avoided.

For me, the first lesson is informed consent. Many patients were not told about the risks of their treatment or about safer alternatives, so they could not make their own choice. Today doctors have to explain the risks and options and respect the decision the patient makes.

The second lesson is candour. Some patients only found out they were infected months or years later, which stopped them getting treatment or protecting their partners. I think being open when something goes wrong is part of respecting a patient.

The third lesson is listening. Families campaigned for decades and were told they had received the best treatment available.

At my part-time job in a café, I once gave a customer the wrong allergy information and had to go back, explain and put it right. It was a small thing, but it showed me how much people value being told the truth straight away.

As a future doctor, I would want to be open with patients, and if I was worried something had gone wrong, I would tell a senior colleague early.

Why this answer works:

• It starts with the facts: a short, accurate summary comes before any opinion
• It picks clear lessons: consent, candour and listening, each tied to something that happened
• It brings in personal experience: the café example shows the student applying the lesson to their own life
• It stays humble: it ends by speaking up early and asking a senior colleague for help

Practise saying answers out loud with someone who’ll ask follow-up questions. Our medicine interview coaching gives you mock interviews with personalised feedback, and there are plenty more questions in our medical school practice interview questions.

Key Takeaway: Open with the facts, choose the lessons that fit the question, and finish with what you would do yourself.

The one thing to take into the room

The infected blood scandal shows what happens when patients are kept from the truth, so build your answer around consent, candour and listening, and speak about the families affected with care.

For related reading, see our guides to the four pillars of medical ethics, the General Medical Council, the Shropshire maternity scandal, the Lucy Letby case and the MMR scandal and Andrew Wakefield, which all raise questions about patient safety and trust.

Key Takeaway: Talk about the patients first, and show that openness with patients is something you already value.
