Comment parler à quelqu'un qui hésite à propos des vaccins

So far, the UK's COVID-19 vaccination programme has been remarkably successful. More than half the UK population had received at least one dose of the vaccine by late April 2021, and the rollout is now extending to younger age groups. By late July, all UK adults should have been offered their first jab.

For many people, getting their vaccine is cause for celebration, marking the end of months of anxiety around contracting COVID-19. Although no vaccine offers 100% protection against the virus - and you need both doses for maximum effectiveness - they do significantly lower rates of death, hospitalisation and serious illness. Getting the vaccine may feel like an important step back towards normal life for all of us.

However, a significant minority of the population is less than thrilled about the idea of getting the jab.

Where does vaccine hesitancy come from?

People within this bracket may be worried about side effects, or concerned about getting a vaccine that didn't exist a matter of months ago. They may have encountered misinformation on social media. Or they may lack trust in the healthcare system at large, questioning whether the vaccine will protect them or whether it's needed at all.

"Vaccine hesitancy is the delay in acceptance or the refusal to accept vaccines despite the availability of vaccines," explains Professor Sam Shah, Chief Medical Strategy Officer at Numan, a digital healthcare provider for men. "It's complex and varies between different groups, conditions and even vaccines. People might be worried about safety, toxicity or quality; they may have had a previous poor experience or they may lack trust in the government or healthcare professionals. They may also have a perception about being at low risk of illness, or lack information. There could be religious beliefs that may contribute to decisions, or even a fear of needles."

Of Brits surveyed in late April, 93% said they'd either had the COVID-19 vaccine or would be likely to have the jab if offered - which still leaves 7% who wouldn't. Younger people were more likely to be vaccine-hesitant (17% of 16- to 29-year-olds surveyed fell into this category), along with people belonging to non-white ethnic groups.

Back in December 2020, just 49% of Black people reported they were likely to have the vaccine, compared to 85% of white people. As of mid-March, a person aged over 70 with black African heritage was 7.4 times more likely not to have had the vaccine than a white person over 70. This is especially troubling when you consider Black people are at heightened risk of death from COVID-19.

Why is this subject so emotive?

In short, the reasons why someone might be vaccine-hesitant are often personal and highly sensitive. In the case of marginalised groups and those living in deprived areas, the hesitancy may be grounded in a long history of feeling failed by the healthcare system.

"For example, some populations have heard doctors in some parts of the world suggest that vaccines should be tested in certain populations or groups. This can contribute to race-specific vaccine hesitancy," says Prof Shah.

On the other hand, the more people who refuse the vaccine, the less able we are to get the pandemic under control. By leaving yourself unprotected, you are also increasing the odds of infection for those around you, including immunocompromised people who can't get the jab themselves.

This means vaccination can be an emotive subject - and proposals like vaccine passports to get into pubs, or mandatory vaccinations for care home workers, tend to stir up strong feelings on both sides.

How to begin a conversation about vaccines

The upshot, then, is that if you want to persuade someone to get the COVID-19 vaccine (or any other vaccine for that matter), you need to be careful about your approach.

"It's really important to be proactive about addressing vaccine hesitancy - people have real concerns and it's important people listen and have a discussion that goes beyond a binary decision," says Prof Shah. "Try to communicate easy-to-understand messages that are tailored to the particular concern, as it'll be different for different people."

Some misconceptions are quite easily debunked. If, for instance, your friend or family member is worried about how quickly the COVID-19 vaccine was rolled out, or is scared because of myths about vaccines causing autisme ou l'infertilité, it's worth reading up on what the testing and approvals process involves. Many people are receptive to hearing new information that might allay their fears, particularly if you're bringing a positive message about the benefits of vaccination.

"Vaccine manufacturers and regulators around the world are constantly monitoring the quality, safety and efficacy of vaccines as they would for any other drug," points out Prof Shah. "The development of the COVID-19 vaccine utilised advances in the treatment of other conditions ranging from coqueluche, rage et l'hépatite, amongst other known technological advances."

How was the vaccine developed so quickly?

Though some anti-vaccination myths suggested that the vaccine isn't safe because it was developed so quickly, no shortcuts were taken to get the vaccine ready. But thanks to previous research and the scale of the project, some of the usual processes were able to happen more quickly than usual, without compromising on safety.

It often takes months or years to recruit enough people to participate in studies. But in the UK alone, over 300,000 people signed up to the National Institute of Health Research COVID-19 vaccine research register.

Once most vaccine studies start, it can take months or years for enough people to catch the disease to know whether the vaccine offers protection. Because COVID-19 has been so rife, the difference between rates of infection in the real vaccine and placebo (non-active) groups became apparent in weeks.

Drug regulatory bodies like the UK's MHRA all prioritised review of the study protocols and results, so they were able to provide their usual robust full analysis in a fraction of the normal time.

Putting risks into perspective

Some people have understandably been concerned by the media coverage surrounding the possible extremely small risk of a blood clot called cerebral venous sinus thrombosis among people getting the AZ vaccine. But these risks need to be put into perspective:

• The risk is somewhere in the region of 1 in 100,000 to 1 in a million people having the vaccine, depending on age and other risk factors. If the vaccination programme had not been under such intense scrutiny, this risk (which is many times smaller than the risks of many widely used medicines) would never have been mentioned in the media.

• The risk of developing the same rare blood clot is 8-10 times higher among people who contract COVID-19 than among people who have the vaccine.

• All the major international safety agencies, including the European Medicines Agency and the MHRA, have confirmed that the benefits of vaccination greatly outweigh the risks.

Don't expect too much from yourself

If you're not confident about arguing your case, or don't know the answers to a friend's questions, you can refer them to trusted sources of information like the Patient website. Pharmacists, doctors and other healthcare professionals also play a major role in putting people's minds at rest.

"Patients can be hesitant about everything from a simple blood test to the flu vaccine. However, the COVID-19 vaccine has thrown a major spanner in the works," says Hussein Abdeh, superintendent pharmacist at Medicine Direct. "In most cases I am able to put the patient at ease by simply talking to them and explaining how a vaccine works and how they are so effective."

Some anti-vaxx arguments might be harder to engage with. If your friend has bought into a conspiracy theory - for instance, the idea that Bill Gates wants to microchip the global population - you might not have much success convincing them otherwise. But it's worth having a discussion anyway about what sources of information they're using and why they're worried.

The most important factor is to come at the discussion from a place of curiosity, not judgement. An all-guns-blazing approach is likely to put the person on the defensive, and may have the opposite effect from the one you're hoping for. You won't be able to persuade everyone to get the vaccine, but it certainly can't hurt to open up a dialogue. Vaccinations are an incredible tool for getting infectious disease outbreaks under control, and the more of us who are able to access them, the better.
