In recent years, the United Kingdom has witnessed a significant decline in public confidence in vaccines. This trend, marked by a decrease in the percentage of adults who believe vaccines are safe and effective, poses serious public health challenges. In 2023, only 70% of UK adults expressed trust in vaccinations, down from 90% in 2018. The issue is further complicated by misinformation online, with 20% of parents reporting exposure to concerning vaccine information. This erosion of confidence coincides with a resurgence in diseases like measles, as seen in outbreaks across major cities such as London, Birmingham, and Bristol.
The decline in vaccine trust is particularly pronounced among younger populations. Among 18-24-year-olds, confidence has dropped from 80% in 2019 to under 60% in 2023. This skepticism translates into lower vaccination rates among children. In England, the first dose of the MMR vaccine reached only 88.9% coverage in 2024, the lowest level in 14 years. Such trends are alarming given the historical context of vaccine hesitancy, notably following the debunked claims linking the MMR vaccine with autism.
The UK Health Security Agency (UKHSA) has expressed grave concerns about these falling vaccination rates. Research by the Vaccine Confidence Project highlights younger groups as experiencing the most significant declines in vaccine confidence over the past four years. Professor Heidi Larson emphasizes the need to engage with these at-risk groups, particularly young people who might become future parents.
The rising skepticism is not isolated to the UK. The World Health Organization reports a global decline in vaccine confidence, with 52 out of 55 countries noting a drop since 2019. In the UK, the proportion of citizens believing that undisclosed harmful side effects exist has risen to 30% in 2024 from 19% in 2019.
Dr. Wall attributes part of this skepticism to "vaccine fatigue," a phenomenon exacerbated by the Covid-19 pandemic. This fatigue affects both the public and healthcare professionals, with some NHS staff reportedly feeling "tired, jaded and fed-up."
The Covid inquiry currently examines various aspects of the vaccine rollout across the UK, focusing on uptake, safety, and public messaging strategies. This investigation sheds light on how societal attitudes towards vaccines have evolved post-pandemic.
"It's 'the people' versus the political and financial elites, with medical and scientific experts seen as among those deemed elitist, speaking a different language and entwined with big business and pharma," – Prof Larson
Such sentiments reflect a broader distrust in establishments perceived as elitist or disconnected from public realities. Dr. Simon Williams notes a shift in perception among patients who question healthcare professionals' motivations.
"Patients would start to say to me, 'why should I trust you, you work for them, you're being paid by them, you're part of the government'." – Dr Simon Williams
This erosion of trust has transformed healthcare providers from being seen as lifesavers to mere components of an untrusted system.
"We very quickly went from being lifesavers to just another part of the system that no-one trusted in some spheres." – Dr Simon Williams
The pandemic has amplified pre-existing confidence issues with vaccines, according to Dr. Wall.
"I think what Covid has done is amplified a confidence issue that was already there and ramped up some of the doubts and question-marks for people." – Dr Wall
To combat misinformation and rebuild trust, it is crucial to focus on education and understanding rather than solely on correcting falsehoods.
"I think we are losing the plot if we only focus on disinformation, and don't start to build an appreciation of how vaccines work and their benefits," – Prof Heidi Larson
Prof Larson stresses the importance of prioritizing younger generations who are increasingly questioning vaccine importance.
"They should really be the priority, because these are potential young parents and if they are questioning the importance of vaccines, then we are in trouble," – Prof Heidi Larson
The sentiment of autonomy also plays a role in vaccine hesitancy.
"Enough of being told what to do, I just don't want your vaccines anymore'" – Prof Heidi Larson
Despite these challenges, experts continue to emphasize the critical role of vaccines in public health.
"Vaccines are always our best defence against infectious, communicable diseases," – Dr Williams
Even small declines in vaccination coverage can lead to significant public health consequences.
"A few percentage drops in the proportion of children covered can make a real difference." – Dr Williams
The pandemic paradoxically undermined public confidence despite showcasing one of history's most successful public health innovations—the rapid development of Covid vaccines.
"It's the great paradox of the pandemic," – Dr Simon Williams
"One of the most successful innovations in public health history, the rapid development of Covid vaccines, has actually had the effect of reducing public confidence in vaccination." – Dr Simon Williams
The rapid spread of misinformation through digital platforms contributes significantly to this decline.
"Now somebody in one corner of the world can post something and suddenly millions of people in another part of the world can see it within seconds," – Dr Williams
