Covid-19 misinformation bolsters anti-vaccine movement

 WASHINGTON, July 4, 2022 (BSS/AFP) - More parents are questioning the

necessity of routine vaccinations for young children. Adults are skipping
shots as well, even for vaccines with a long safety record.

The trend comes amid a wave of misinformation and disinformation about Covid-
19 and the vaccines that helped to stem pandemic deaths. Politicization of
the Covid-19 shots has bolstered the anti-vaccine movement, contributing to
the decline in routine immunizations for measles, polio and other dangerous
diseases.

"They ask if these are truly necessary, or if we can give them at later
times," said Jason Terk, a Texas pediatrician and spokesperson for the
American Academy of Pediatrics.

"This is not the majority of parents, but we are seeing a higher number."

The anti-vaccine movement has mushroomed as its messages on social media are
amplified by conservative political figures as well as foreign influence
operations, whose vaccine disinformation efforts pre-date the pandemic.

With routine immunization rates falling, concerns are growing about a
resurgence of diseases which had largely been eradicated in many parts of the
world.

In the United States, the percentage of kindergarten children with
recommended immunizations fell a percentage point to 94 percent in the 2020-
21 school year, representing some 35,000 children unvaccinated.

"I refer to it as the parallel contagion," Terk said. "This seems to have at
its origin hesitancy in Covid-19 vaccinations and increasing distrust of
vaccines and the bodies we've relied on to keep us healthy and well."

Dramatic changes were seen in some states, especially during the height of
the pandemic: researchers found a 47 percent drop in immunization rates in
Texas among five-month-olds and a 58 percent decline for 16-month-olds
between 2019 and 2020.

The researchers, writing in the scientific journal Vaccine, said the declines
resulted from shelter-in-place restrictions and vaccine exemptions, but also
to "an aggressive anti-vaccine movement in Texas."

Washington state reported a 13 percent decline in childhood immunization
rates in 2021 compared with pre-pandemic levels and Michigan's vaccination
rate for toddlers fell last year to 69.9 percent, the lowest in a decade.

- Adults too -

Adult and adolescent inoculation rates have also dropped for vaccines
protecting against diseases such as influenza, hepatitis, measles, tetanus
and shingles, according to health consultancy Avalere, which analyzes insurer
claims.

This has led to an estimated 37 million missed vaccination doses from January
2020 to July 2021 for adults and children ages seven and older, Avalere
found.

Declines early in the pandemic can be attributed to shelter-in-place orders
and social distancing, but "there is a risk of a bleed-over" of Covid vaccine
misinformation, which affects other vaccines which have a longstanding safety
record, noted Avalere managing director Jason Hall.

Social media have helped create a coalition that includes true anti-vaccine
believers, libertarians and conservative political figures. These segments
have been amplified by disinformation actors from Russia and elsewhere, said
David Broniatowski, a George Washington University professor and associate
director of the school's Institute for Data, Democracy and Politics.


"People have been opposing vaccines for as long as there have been vaccines,
but they've gotten more sophisticated over the past 10 years and a lot of
that has been because of the ability to organize on social media across
boundaries," said Broniatowski, who researches vaccine disinformation.

He noted that while anti-vaccine activists, libertarians and foreign agents
are not necessarily coordinating, "they have found common cause" in opposing
vaccine mandates.

"One of the main changes we've seen is a pivot away from focusing on vaccines
per se as a health issue to a civil rights and a political issue," he added.

Conspiracy theories have surged during the pandemic, according to a 2021
YouGov poll, which found 28 percent of Americans and significant numbers in
other countries say the truth about the harmful effects of vaccines is being
"deliberately hidden."
- Foreign actors -

Broniatowski said that foreign disinformation agents "use vaccines as a wedge
issue that can mobilize a segment of the population."

A 2018 paper co-authored by Broniatowski in the American Journal of Public
Health found anti-vaccine Twitter activity was amplified by Russian trolls
from 2014 to 2017 as part of an effort to promote discord and undermine
confidence in the health system.

Research from the Center for European Policy Analysis showed both China and
Russia have promoted Covid-19 vaccine misinformation, in part to show that
Western governments are incompetent and can't be trusted.

"There's been a concerted effort on the part of these actors to diminish the
standing of science because it serves their political purposes," Broniatowski
said.

The problem is growing globally as well. A United Nations report last year
found 23 million children worldwide missed out on routine immunizations in
2020. In the Americas region, the percentage of fully inoculated children
fell to 82 percent from 91 percent in 2016 due to factors including funding
shortfalls, vaccine misinformation and instability.

This is likely to create more health risks down the road from diseases which
have been mostly contained.

"We had certain thresholds of protection to keep these diseases from being
relevant from a public health point of view," Terk said.

"The more people pushing back, the more likely we'll have pockets of
vulnerability."
