Yahoo News Measles outbreaks and the rise of populist politics go hand in hand
The World Health Organisation (WHO) has announced that it no longer considers measles to be eradicated in the UK. Albania, the Czech Republic and Greece have also lost their measles-free status.
It is a coincidence that the news broke not long before Boris Johnson, the UK prime minister, provoked widespread outrage by proroguing parliament. But the increasing prevalence of measles must be understood in the broader context of rising populist sentiment and drawn-out political crises.
Measles is a highly infectious and potentially deadly disease, but it can be prevented with a cheap and easily administered vaccine. If over 90-95 per cent of a community is vaccinated, “herd immunity” is achieved and outbreaks are unlikely to occur. When the measles vaccine was introduced in 1963, the disease killed about 2.6 million people a year. The number of measles cases has steadily declined since then, and it is estimated that the vaccine has saved more than 21 million lives since the turn of the century.
Vaccines are widely agreed to be one of the great achievements of the scientific age. A survey of eminent historians by The Atlantic put vaccines as number eight in a list of the “greatest breakthroughs since the wheel”. And an article by the US librarian of congress published in National Geographic placed vaccines fifth out of 10 inventions “that changed the world”.
But in the past few years, the remarkable progress made by vaccines has gone into reverse, particularly in the west. In Europe, there were about 5,000 cases of measles in 2016, 24,000 in 2017 and 84,000 in 2018. According to recent WHO data, there have already been 90,000 measles cases in the first six months of this year. And the US is experiencing its biggest measles outbreak for 27 years.
Measles outbreaks are a consequence of falling vaccine coverage, which appears to result from increasingly widespread anxieties about vaccine safety. These fears go back at least to the 18th century when efforts to inoculate people against smallpox in Boston, US, were met with fierce resistance. Contemporary concerns about vaccine safety, however, are usually traced to debunked claims that there is a link between the MMR (measles, mumps and rubella) vaccine and autism.
Discredited theory that refuses to die
This connection is rejected by mainstream scientists. Andrew Wakefield, the source of this conspiracy theory, was struck off by the UK’s General Medical Council for acting dishonestly and irresponsibly, and his published research was retracted by The Lancet. Earlier this year, a study of over 650,000 children in Denmark concluded that there was no evidence of a connection between MMR and autism – even among children who were seen to be of heightened risk, such as those with autistic siblings.

Still, Wakefield’s ideas continue to have enormous influence. A survey of 2,600 parents published in January by the Royal Society for Public Health shows that 21 per cent of parents in the UK think MMR causes unwanted side effects and almost 10 per cent of parents chose not to give their child the MMR vaccine, mainly because of fears about side effects.
In June, the Wellcome Trust published the results of a survey of more than 140,000 people. Only 73 per cent in northern Europe (which includes the UK), 59 per cent in western Europe and 40 per cent in eastern Europe agreed with the statement that vaccines are safe. The figure was 72 per cent for the US. The WHO listed vaccine hesitancy as a top 10 global health threat for 2019 and one that “threatens to reverse progress made in tackling vaccine-preventable diseases”.
The NHS points out “vaccination is safe and important” and the WHO states that “vaccines are safe”. This raises the question: why do so many people believe unproven theories over the informed advice of medical doctors and public health authorities?
Post-truth age
One common answer stresses how the internet has changed the way we access information and communicate. The aforementioned survey by the Royal Society for Public Health also showed that half of the parents of children under five in the UK are often or sometimes exposed to negative messages about vaccines on social media and online forums.
Interestingly, a study published last year revealed that the same Russian trolls and bots that interfered in the US presidential elections on behalf of Donald Trump spread disinformation about vaccines. This suggests that the Russian state is using the topic of vaccine safety to spread discord in the west.
But growing vaccine hesitancy indicates a broader breakdown in trust in elites and experts that is behind Brexit and other political crises. In the run-up to the 2016 referendum, Michael Gove claimed that people have had enough of experts. He was referring to economists, but this sentiment has wider relevance in the so-called “post-truth” age, when appeals to emotion appear to be more effective at influencing opinion than facts and evidence.
My own research shows that western European countries with the highest levels of electoral support for populist political parties, such as Greece, Italy and France, also have the highest percentage of people who do not believe that vaccines are important, safe or effective according to the Vaccine Confidence Project. In contrast, countries that have the lowest levels of populist votes, such as Portugal and Belgium, also have the lowest levels of vaccine hesitancy.
The link between populism and vaccine hesitancy can be seen when we look at individual-level data. Survey results published in The Economist in 2014 showed that Ukip voters were almost five times more likely to believe that the MMR vaccine is unsafe. According to more recent data, one-third of Ukip voters believed vaccines were unsafe compared with 10 per cent of Labour voters and 11 per cent of Conservative voters. We found similar patterns throughout Europe: supporters of right-wing populist parties were much more likely to question the safety of vaccines.
Breakdown in trust
It is interesting to note that the three other European countries that lost their measles-free status are also in the midst of profound crises precipitated by a breakdown in trust in the politicians.

In June, Albania’s elections were boycotted by the main opposition party who accused the prime minister of previous electoral fraud and corruption. In the Czech Republic, hundreds of thousands of people have taken to the streets this summer to protest against alleged economic fraud perpetrated by the billionaire prime minister Andrej Babis. Greeks have suffered massively since 2008, with GDP still 20 per cent lower than pre-crisis levels. Alexis Tsipras’s left-wing government was recently defeated by New Democracy, which has been described by some observers as a right-wing populist party.
All this shows how political crises and measles go hand in hand. Just as Boris Johnson’s manoeuvring does not undo all the progress that has occurred in British politics since Charles I, the UK losing its measles-free status does not signify a return to the Dark Ages. It is nevertheless alarming to see how precarious both the rule of law and public health are in the current political climate.
