Trust in science falls as Covid-era confidence fades, global survey finds
AI generated
The Covid-era surge in public trust in science has largely faded, with the steepest drop among people struggling financially, according to one of the largest global surveys of attitudes toward science.
uncertain
surge → fall → science
Across countries surveyed before, during and after the pandemic, 72% of people expressed at least some trust in science in 2025, down from 80% in 2020 and 77% in 2018.
asserted
% → survey → 2018
Strong trust in scientists also dropped below its pre-pandemic level, according to the Wellcome Global Monitor, which surveyed more than 140,000 adults worldwide.

The retreat has potentially far-reaching consequences for public health as vaccination rates decline and preventable diseases resurge.
asserted
diseases → have → health
The US is experiencing its worst measles outbreak in three decades, with almost 3,900 cases this year, while childhood vaccination rates have fallen below levels needed to prevent outbreaks in many communities.
asserted
rates → experience → communities
The findings come as misinformation and conspiracy theories complicate responses to health threats, and scientific institutions in some countries face growing political and funding pressures.
asserted
institutions → come → pressures
The survey does not establish what caused the decline, though the politicisation of science during the pandemic probably contributed, said John-Arne Røttingen, chief executive officer of Wellcome, a London-based health research foundation.

Røttingen → establish → Wellcome
Vaccines, masks and public-health measures became politically contested, he said.

“Politics has made some of science more political and that has led to the polarisation and maybe a lack of trust,” Røttingen said in an interview from Berlin.

The decline was particularly pronounced among people experiencing financial hardship.
asserted
decline → pronounce → hardship
In 2025, 39% of those who said they were living comfortably reported a lot of trust in science, compared with 20% among those who find it difficult to get by.
asserted
it → say → those
That divide has widened since the pandemic.
Strong trust fell 16 percentage points among those struggling financially between 2020 and 2025, compared with 10 points among those living comfortably.
asserted
trust → widen → those
Countries with greater economic inequality also tended to have lower trust in science, as did places where people had less confidence in public institutions or perceived greater corruption.
asserted
people → tend → corruption
People struggling financially may see science as part of a broader system that is not working for them, Røttingen said.

Røttingen → struggle → them
“Science is seen as one of those institutions that are not delivering,” he said.

Scientists also need to do a better job of reaching such communities, he said.

Experiences → associate → trust
While 26% globally said they had a lot of trust in science, that rose to 43% among people with a lot of confidence in their country’s hospitals and health clinics.

The survey, produced by Wellcome with Gallup and Ipsos, points to a connection between trust and vaccinations.
asserted
survey → produce → trust
When respondents were asked what they do when a doctor or nurse recommends a vaccine, 34% said they wanted it immediately, 48% preferred to think about it and 15% said they did not get vaccines at all.
asserted
they → ask → vaccines
Those who wanted a recommended vaccine immediately were twice as likely to express a lot of trust in science as those who did not vaccinate – 36% versus 18% – though Wellcome cautioned that other factors also shape vaccine decisions.
asserted
factors → want → decisions
Falling vaccination coverage shows how mistrust can have consequences beyond the individual because vaccines also protect people in the wider community who can’t be vaccinated or don’t mount a strong immune response, Røttingen said.
asserted
Røttingen → fall → response
“I am worried” about rising measles cases in the US and Europe, he said.
asserted
he → rise → US
Public willingness to use new vaccines and other technologies will also be crucial in future health emergencies, he said.
