Hepatitis C: Testing, Prevention and Cure
There is no hepatitis C vaccine: but unlike hepatitis B, hepatitis C can now be cured in most people with a short course of tablets.
People often arrive asking for a hepatitis C vaccine. There is not one, and it is worth being direct about that rather than leaving the impression that one exists. Decades of research have not produced a licensed vaccine, largely because the virus mutates rapidly and exists as several genetically distinct genotypes.
The good news is considerably better than the bad. Hepatitis C went from a chronic, difficult-to-treat infection to a curable one within about a decade. Direct-acting antiviral tablets cure the great majority of cases in 8 to 12 weeks, with few side effects. The obstacle now is not treatment. It is that most infected people have no idea they are infected.
At a glance
What is available for hepatitis C, and what is not.
| Vaccine or test | Status | Schedule | Detail |
|---|---|---|---|
| Hepatitis C vaccine | No vaccine exists | Not available | No licensed vaccine exists anywhere. The virus mutates rapidly and its envelope proteins vary widely between genotypes, which has defeated vaccine development so far. Prevention relies on avoiding blood-borne exposure. |
| HCV antibody test | Recommended | Single blood test | The first-line screening test. A positive result means you have been exposed at some point, but antibodies persist even after the infection clears, so a positive antibody test alone does not confirm current infection. |
| HCV RNA (PCR) test | Conditional | After a positive antibody result | Detects the virus itself. This is what confirms whether infection is currently active. Roughly a quarter of people clear hepatitis C spontaneously, and they remain antibody-positive but RNA-negative. |
| Hepatitis A and B vaccination | Recommended | If not already immune | Relevant here because someone with hepatitis C should not also be carrying preventable liver infections. Vaccinating against A and B protects a liver already under strain. |
Why the test result needs two steps
This trips people up regularly. The antibody test tells you whether your immune system has ever encountered hepatitis C. It stays positive for life, even if the infection cleared on its own, which happens in roughly a quarter of cases.
So a positive antibody result raises a question rather than answering one. The RNA test answers it: virus detected means active infection needing treatment; virus not detected means past infection that resolved. Do not treat a positive antibody test as a diagnosis on its own.
Who should be tested
Hepatitis C is frequently silent for years or decades, which is why testing is based on exposure history rather than symptoms.
- Anyone who received a blood transfusion or blood products before routine screening was introduced.
- People who have ever injected drugs, even once, and even long ago.
- Anyone who has had tattoos, piercings or shaving with equipment that may not have been sterile.
- Healthcare workers after a needlestick injury.
- People on long-term haemodialysis.
- Children born to hepatitis C positive mothers.
- Anyone with unexplained abnormal liver function tests.
What prevention actually looks like
Without a vaccine, prevention is entirely about avoiding blood-to-blood contact. Hepatitis C is not spread by sharing food, hugging, coughing or casual household contact.
- Never share needles, syringes or any injecting equipment.
- Use only licensed tattoo and piercing studios with single-use needles.
- Do not share razors, toothbrushes or nail clippers.
- Ensure medical and dental instruments are properly sterilised.
- Follow standard precautions if you handle blood at work.
Treatment changed completely
Older interferon-based treatment took up to a year, caused significant side effects, and failed often. Direct-acting antivirals replaced it: oral tablets, typically 8 to 12 weeks, cure rates above 95 percent across genotypes, and side effects that most people describe as mild.
Cure is confirmed by an undetectable RNA test 12 weeks after finishing treatment. Note that being cured does not make you immune, reinfection is possible if you are exposed again, because there is no lasting protective immunity and no vaccine to provide it.
Frequently asked questions
Is there a hepatitis C vaccine?
No. Despite decades of research, no licensed hepatitis C vaccine exists. The virus mutates rapidly and has several genetically distinct genotypes, which has made vaccine development extremely difficult. Prevention relies on avoiding blood-borne exposure.
Can hepatitis C be cured?
Yes, in most cases. Direct-acting antiviral tablets taken for 8 to 12 weeks cure over 95 percent of people, with mild side effects. Cure is confirmed by an undetectable RNA test 12 weeks after treatment ends.
I tested positive for hepatitis C antibodies. Am I infected?
Not necessarily. Antibodies persist for life even if the infection cleared, and about a quarter of people clear it spontaneously. An HCV RNA test is needed to determine whether the virus is currently present.
How does hepatitis C spread?
Through blood-to-blood contact: shared injecting equipment, unsterile tattooing or piercing, unscreened transfusions, needlestick injuries. It is not spread by sharing food, hugging, coughing or ordinary household contact.
If I am cured, can I get hepatitis C again?
Yes. Successful treatment does not produce lasting immunity, and there is no vaccine to provide it. Reinfection is possible with further exposure, so the same precautions continue to apply after cure.
Book a hepatitis C test
There is no vaccine, so testing is the whole game. If the antibody test is positive we arrange the RNA test that confirms whether treatment is needed.
