COVID-19 misinformation: scientists create a ‘psychological vaccine’ to protect against fake news

A ‘psychological vaccine’ has proven effective in countering belief in COVID-19 conspiracies.

Anti-vaccination groups are projected to dominate social media in the next decade if left unchallenged. To counter their viral misinformation at a time when COVID-19 vaccines are being rolled out, our research team has produced a “psychological vaccine” that helps people detect and resist the lies and hoaxes they encounter online.

The World Health Organization (WHO) expressed concern about a global misinformation “infodemic” in February 2020, recognising that the COVID-19 pandemic would be fought both on the ground and on social media. That’s because an effective vaccine roll out will rely on high vaccine confidence, and viral misinformation can adversely affect that confidence, leading to vaccine hesitancy.

We recently published a large study which found that higher belief in misinformation about the virus was consistently associated with a reduced willingness to get vaccinated. These findings were later reaffirmed in a subsequent study which found a significant relationship between disinformation campaigns and declining vaccination coverage.

The spread of false information about COVID-19 poses a serious risk to not only the success of vaccination campaigns but to public health in general. Our solution is to inoculate people against false information – and we’ve borrowed from the logic of real-life vaccines to inform our approach.

When looking for ways to mitigate misinformation, scientists are confronted with several challenges: first, rumours have been shown to spread faster, further and deeper in social networks than other news, making it difficult for corrections (such as fact-checks) to consistently reach the same number of people as the original misinformation.

Second, even when someone is exposed to a fact-check, research has shown that corrections are unlikely to entirely undo the damage done by misinformation – a phenomenon known as the “continued influence effect”. In other words, approaches to combating misinformation “post-exposure” are probably insufficient.

Our work in recent years has therefore focused on how to prevent people from falling for misinformation in the first place, building on a framework from social psychology known as inoculation theory.

Mental resistance

Psychological inoculations are similar to medical vaccines. Exposing someone to a severely weakened dose of the “virus” (in this case misinformation) triggers the production of mental “antibodies”, thus conferring psychological resistance against future unwanted persuasion attempts.

However, rather than only “vaccinating” people against individual examples of misinformation, we instead focus on the more general ways in which people are misled – manipulation techniques such as the use of excessively emotional language, the construction of conspiracy theories, and the false testimony of fake experts.

To do so, we developed a series of online games in which players learn how misinformation works from the inside by being encouraged to create their own fake news: Bad News (about misinformation in general), Harmony Square (about political misinformation) and Go Viral!, which is specifically about misinformation around COVID-19.

Research has shown that a powerful way to induce resistance to persuasion is to make people aware of their own vulnerabilities. In our games, players are forewarned about the dangers of fake news and encouraged to actively generate their own antibodies through gradual exposure to weakened examples of misinformation in a simulated social media environment.

When we assessed the success of these projects, we found that playing a misinformation game reduces the perceived reliability of misinformation (even if participants had never seen the misinformation before); increases people’s confidence in their ability to assess the reliability of misinformation on their feed; and reduces their self-reported willingness to share misinformation with other people in their network. We also found that similar inoculation effects are conferred across cultures and languages.

We then looked at how long the games’ inoculation effect lasted and found that people remained significantly better at spotting manipulation techniques in social media content for at least one week after playing our game Bad News. This “immunity” lasted up to three months when participants were assessed at regular intervals each week. We see these prompts as motivational “booster shots”, topping up people’s immunity to misinformation by staying engaged.

Herd Immunity

Of course, our work is not without its limitations. Although these games have been played over a million times around the world and have been shared by governments, the WHO, and the United Nations, not everyone is interested in playing an online game.

But the game itself functions as just one kind of “virtual needle”. A global “vaccination programme” against misinformation will require a suite of different interventions. For example, we’re working with Google’s technology incubator “Jigsaw”, and our colleague Professor Stephan Lewandowsky, to develop and test a series of short animated inoculation videos.

Like the game, these videos forewarn and administer a micro-dose of a manipulation technique, which primes the watcher to spot similar techniques in the information they subsequently consume online. We intend to publish our study on the efficacy of video vaccines later this year.

As the pandemic continues to wreak havoc worldwide, a successful vaccine rollout is of vital interest to the global community. Preventing the spread of misinformation about the virus and the vaccines that have been developed against it is a crucial component of this effort.

Although it is not possible to inoculate everyone against misinformation on a permanent basis, if enough people have gained a sufficient level of psychological immunity to misinformation, fake news won’t have a chance to spread as far and as wide as it does currently. This will help arrest the alarming growth of anti-vaccination sentiment on the internet.

Continuing rapid expansion, Thermo Fisher says it will add on plasmid DNA manufacturing site in California

It’s been a whirlwind week for Thermo Fisher.

Over the course of five days prior to Wednesday, the Massachusetts CDMO had announced two major expansion projects across the globe, both of which will increase the company’s footprint in the vaccine marketplace. And now, Thermo has unveiled a third major expansion project — this time, a new cGMP facility specializing in the production of plasmid DNA at its Carlsbad, California site.

The 67,000-square-foot facility, expected to be completed in the first half of 2021, will allow the manufacturing giant to expand its clinical and commercial capabilities for therapeutics involving independently-replicating DNA molecules. The facility will add 150 jobs over the next year, Thermo Fisher said in a press release.

Studying plasmid DNA as a critical raw material could prompt discoveries of life-saving cancer treatments and aid in mRNA vaccine production.

Mike Shafer

The latter is especially relevant now, as both the Pfizer-BioNTech and Moderna Covid-19 vaccines are based around mRNA technology. The Carlsbad site will also have the capacity to produce large-scale plasmid DNA as a primary drug substance for DNA therapies. Such capacity is essential, Thermo senior VP Mike Shafer said in the press release, as the global plasmids market is growing so rapidly that supply currently can’t meet the projected demand.

“Our new state-of-the art site will not only tackle the supply bottleneck for our customers, but also uniquely positions us to deliver robust, end-to-end cell and gene therapy capabilities,” Shafer said. “Our customers can leverage our deep industry knowledge and expertise in the complexities of cell and gene therapy at all points along the pathway to commercialization — from research and preclinical development to clinical and now expanded commercial and supply chain services.”

In addition to the Carlsbad facility, Thermo Fisher also has new facilities in Rheinfelden and Weil am Rhein, Germany, going online this month and next, respectively. Those facilities will focus on clinical supply chain continuity, namely in specialized cold-chain and cryogenic expertise.

Thermo Fisher also recently announced expansion projects at facilities in Greenville, NC; Ferentino and Monza, Italy; and Swindon, England, to widen the range of options available to customers, especially in the vaccine arena.

Overview: The prospects of a UK-EU deal and US stimulus continue to underwrite risk appetites and weigh on the dollar.  Equity markets are moving higher.  Led by Australia and China, the MSCI Asia Pacific Index rose to new record highs, while Dow Jones Stoxx 600 in Europe is at its best level since February.  US shares are also trading higher.  Bond markets are quiet, with European yields paring yesterday's gains while the US 10-year benchmark is hovering around 0.92%.  The dollar has lurched lower against nearly all the world currencies today.  The Norwegian krone, aided by a central bank suggesting it could be among the first major central banks to begin normalizing monetary policy (not until H1 22). The Australian dollar,  boosted by a strong employment report, are leading the majors.  The euro's roughly 0.25% gain to a new 18-month high is a laggard.  Meanwhile, emerging market currencies are mostly higher, and the JP Morgan Emerging Market Currency Index is higher for the third consecutive session.  Gold is shining in the weak dollar environment.  It has risen by about $50 an ounce over the past three sessions, and straddling $1880, it reached its best level in nearly four weeks.  Oil is bid as well.  Ideas that demand will improve, and a drawdown in US stocks, coupled with the dollar's weakness, lifted the January WTI contract to almost $49 a barrel, while Brent is closing in on $52.  

Asia Pacific

For the second month in a row, Australia reported employment data considerably better than economists forecast.   It created more than double the 40k jobs the Bloomberg median forecast anticipated, and the October surge pushed even higher to 180.4k (from 178.8k).  Nearly all the new jobs were full-time positions (84.2k).  While the participation rate increase to 66.1% from 65.8%, the unemployment rate eased to 6.8% from 7.0%.  Last November, the participation rate was 65.9%.

China avoided being cited as a currency manipulator by the US Treasury Department, but it remains on its watch list. It renewed its call for greater transparency.  It noted as many observers have that its large current account surplus, relatively steady yuan, and a small increase in reserves does not add up.  It notes that large banks are short yuan.  No one has argued that the yuan is free-floating.  It is not fully convertible.  Several other areas are problematic, including the rising errors and commissions catch-all category. 

MSCI announced that, like the other benchmark providers, it too was going to drop companies cited by the US as tied to the Chinese military.  MSCI will drop seven companies in early January.  S&P Dow Jones is dropping eight companies, and FTSE Russell is dropping 8.  A further adjustment could be necessary, as the subsidiaries and affiliates of the 35 companies cited by the US were not excluded on this first cut.  MSCI estimated that 0.04% of its global benchmark and 0.25% of its emerging market index are impacted.  After surveying 100 fund managers, MSCI concluded that reversing the decision will not a top priority for the Biden administration.   

With the US Treasury keeping Japan its fx watch list as well, Japanese officials may be quieter as the dollar is poised to break below JPY103 than they were a month ago when the dollar was slipping through JPY104. The greenback has not been above JPY103.60 in Asia and is testing JPY103 in the European morning.  This is a new nine-month low for the dollar, which hit JPY101.20 in the March chaos.  The Australian dollar jumped above $0.7600 and is at a new 18-month high near $0.7640.  The next chart point is around $0.7675.  It is the fourth consecutive gain for the Aussie.  Barring a dramatic reversal tomorrow, it will be the seventh straight weekly advance that began near $0.7000 at the end of October.   The PBOC's reference rate for the dollar was CNY6.5362, spot on the Bloomberg bank survey's median forecast.  The yuan is flat on the day.  Against the offshore yuan, the dollar traded to CNH6.50 before returning to yesterday's settlement level (~CNH6.5125).  

Europe

On the heels of the Treasury's announcement, the Swiss National Bank argued that it is not manipulating its currency, but it will continue to intervene as necessary.  All intervention is not manipulation, and if a country acts like a judge and a jury in determining the difference, it undermines the effort for international cooperation. At the conclusion of its policy meeting today, the SNB left rates unchanged and reiterated that the franc was "highly valued."  SNB President Jordan argued that its intervention is not aimed at securing a trade advantage but fighting deflationary pressures.  Unlike the US, eurozone, and Japan, there are not sufficient domestic bonds for its to buy as a result of its fiscal policies.  Note that the SNB's reserves have risen by more than $100 bln in H1 20. 

Norway's central bank sees a somewhat faster increase in rates starting in H2 2022 than it did in September.  It makes Norway a leading candidate to be among the first of the high-income countries to begin normalizing policy.   The Norges Bank has run a fairly orthodox policy.  No QE.  No negative rates.  The government did tap the $1.2 trillion sovereign wealth fund for resources.   The currency is the weakest of the majors this year, and that may be helping keep price pressures firm and allowing it to contemplate a hike in 18 months.  

The outcome of the Bank of England meeting is awaited.  No change is in rates, or Gilt purchases are expected.  Barring a surprise, it will be a non-event for sterling, where the market is focused on the weak dollar backdrop and the prospects for a last-minute UK-EU deal.  We had been skeptical that a deal could be struck.  From the outside, it looked like an old married couple talking at each other and not to each other, and there was much posturing.  The UK was jealously seeking to reassert what it sees as its sovereignty. The EU was jilted and determined not to give any incentive whatsoever to others who might contemplate leaving.  Still, since the middle of last week's  Johson/von der Leyen dinner, we have sensed a change and a greater commitment to getting a deal done.  And at the same time, we continue to recognize that even with an agreement, there will be frustrating disruptions in the UK-EU trade early next year. 

The euro pushed to nearly $1.2245 in late Asia turnover and has stabilized in the European morning.  An option for 2.2 bln euros expires tomorrow at $1.2250.  Support now is seen in the $1.2180-$1.2200 area.  Sterling is trading higher against the dollar for the fourth consecutive session and is approaching $1.36.  It finished last week near $1.3225. Partly, this reflects the weak dollar environment, but sterling is also recovering against the euro.  The euro is slipping below GBP0.9000 after hitting GBP0.9230 at the end of last week.  Important support is seen near GBP0.8980, which houses the lows from earlier this month and the 200-day moving average.  A convincing break could target GBP0.8900.  

America

The Federal Reserve said little new and did nothing.  What it did say was important, though. It linked its future bond purchases to "substantial" progress toward its targets.  The median forecast of the members for growth was ratcheted up and unemployment down.  In September, four officials saw a hike in 2023 as likely being appropriate, and now five do.  The extension of the dollar swaps and repo facility for foreign central banks is simply prudent and predictable, even if the former is a shadow of its former self. The latter does not appear to have been used.  The markets wobbled initially; maybe disappointment in some quarters that the pace and composition of its bond purchases were unchanged, but it quickly found its footing.  Stocks firmed into the close, and the long-end yields pulled back.  

Treasury issued its long-overdue report on the international economy and the foreign exchange market.  It cited Switzerland and Vietnam as currency manipulators and added India, Thailand, and Taiwan to the watch-list.  The watch-list also includes China, Japan, South Korea, Germany, Italy, Singapore, and Malaysia.  It is the first time since China was cited last year (and reversed quickly after signing the Phase 1 trade deal), which itself was the first time since 1994 that one or more countries were cited as manipulators.   It was a mechanistic exercise.  There are three criteria, bilateral imbalance with the US, large global imbalance, and repeated intervention on one side of the market.  It makes no difference if a currency is overvalued, as is the Swiss franc or is too small and too poor, like Vietnam.  The currency manipulators are to enter into talks with the US.  Treasury Secretary Mnuchin will not be there.   When Mnuchin took office, there was a coherent dollar policy.  Since 1995, the US refrained from talking the dollar down.  Rubin's strong dollar policy stuck more or less.  For the most part, other large countries refrained from doing the same.  It was an arms control agreement of sorts.  China's behavior complicated matters, but the dollar policy is in disrepair. 

The US reports weekly jobless claims (a small decline is expected after last week's surprise increase), housing starts and permits (among the sectors leading the recovery), and the Philadelphia and Kansas City Fed surveys (likely softer).  These data points do not have the heft to reverses the dollar's weakness or substantially alter views of the economy.  The weakness seen in yesterday's retail sales bodes ill for next week's more comprehensive personal consumption report.  The flash PMI suggests the economic momentum waning into year-end, especially in services, which seems related to the pandemic.  Today, Canada has a light agenda after yesterday's CPI, where the firmness of the headline masked flat underlying measures.  Tomorrow it reports October retail sales, which are most unlikely to match September's strength (1.1% headline gain and 1.0% excluding autos.   Mexico's central bank meets and is widely expected to keep the overnight target rate at 4.25%.  There was one dissent last month, and it could be repeated again. Still, the majority seem to want to wait for confirmation that price pressures are moving lower in a sustained fashion rather than a one-off related to sales discounts.  

The US dollar is trading heavily against the Canadian dollar near CAD1.2700.  The 2.5-year low was set a couple of days ago, a little below CAD1.2680.  The price action has been chopped and has seen intraday upticks extent to almost CAD1.2800.  Note that today's high of CAD1.2750 matches the strike of a $1.1 bln option that expires today.  The greenback tested the MXN20.25 level earlier this week.  That may have been the bounce that some had looked for.  A four-day dollar bounce ended Tuesday, and today it is offered for the third consecutive session.   It is trading near MXN19.75, and the low seen last week was near MXN19.70.  A break of that targets the MXN19.50 area.

U.S. vaccine campaign grows as COVID-19 kills 3,000-plus Americans daily

Daily U.S. deaths from Covid-19 surpassed 3,000 for the third time in a week as the country expanded its vaccination program and Congress progressed toward approving financial relief for pandemic-stricken America.

Daily U.S. COVID-19 deaths again top 3,000 as officials scurry to distribute vaccine

WASHINGTON (Reuters) – The United States on Wednesday widened its network for administering COVID-19 vaccines to doctors and nurses on the frontlines of a pandemic killing more than 3,000 Americans a day, even as a major storm threatened to slow progress on the East Coast.

While medical professionals at a growing number of hospitals rolled up their sleeves, lawmakers on Capitol Hill said they were nearing a long-elusive bipartisan deal on $900 billion in economic relief to pandemic-hit U.S. workers and businesses.

The aid package, to be attached to a massive spending bill that must pass by Friday to avert a federal shutdown, was not expected to include COVID-relief funds for state and local governments, as Democrats wanted, or protections for companies from pandemic-related lawsuits, as sought by Republicans.

Rollout of the first tranche of 2.9 million doses of a newly authorized vaccine from Pfizer Inc and German partner BioNTech SE was in its third full day, with shipments headed to 66 more distribution hubs nationwide.

A second vaccine from Moderna Inc could win emergency-use approval from the U.S. Food and Drug Administration this week.

Express delivery companies FedEx and United Parcel Service, sharing a leading role in vaccine shipments, said they were monitoring potential impacts of heavy ice and snow that began to disrupt transport along the Eastern Seaboard.

U.S. Army General Gustave Perna, overseeing the government’s Operation Warp Speed campaign, said FedEx and UPS have developed contingency plans to keep any delayed vaccine shipments secure until they can be “delivered the next day.”

“We are on track with all the deliveries we said we were doing,” Perna told reporters at a briefing. He cited a minor glitch involving four trays of vaccine – two sent to California and two to Alabama – that arrived at temperatures lower than prescribed. The trays in question were shipped back to Pfizer and later replaced, Perna said.

Some 570 other vaccine distribution centers received the bulk of the initial batch of shipments on Monday and Tuesday, and an even larger wave was due for delivery to 886 additional locations on Friday, Perna said.

From each distribution site, vaccine doses were divided up among area hospitals and administered to healthcare workers, designated as first in line to be immunized. Some were also going to residents and staff of long-term care facilities. Later vaccine rounds will go to other essential workers, senior citizens and people with chronic health conditions.

U.S. President-elect Joe Biden, who has said he would get the vaccine publicly to help instill confidence in its safety, is expected to receive his first injection as soon as next week, according to his transition team.

Biden, 78, is in a high-risk category for the coronavirus due to his age.

It will take several months before vaccines are widely available to the public on demand, and opinion polls have found many Americans hesitant about getting inoculated.

Political leaders and medical authorities in the meantime have launched a media blitz assuring Americans that the vaccines are safe while urging them to avoid growing weary of social distancing and mask-wearing while the pandemic rages on.

“It is not over yet,” Dr Anthony Fauci, a member of the White House coronavirus task force, told CBS News. “Public health measures are the bridge to get to the vaccine, which is going to get us out of this.”

Data shows surging infections and hospitalizations are driving healthcare systems to the breaking point across much of the country, with many intensive care units at or near capacity.

The United States reported at least 3,459 additional coronavirus deaths on Wednesday alone, a record that marks the fourth time in a week the daily toll has surpassed 3,000, according to a Reuters tally. The seven-day average has topped 2,500 lives lost every 24 hours for the first time this week.

To date, COVID-19 deaths total more than 304,000 nationally, while the mounting case load of 16.7 million known infections represents roughly 5% of the U.S. population.

With hospitalizations setting a record for the 19th day in a row – nearly 113,000 patients under treatment on Wednesday – health experts warn that fatalities will rise higher still in the weeks ahead, even as the vaccine campaign steadily expands.

Another 2 million doses of the Pfizer vaccine and 5.9 million doses of Moderna’s vaccine could be allocated next week, U.S. Health Secretary Alex Azar told a conference call. Both require two doses, given three or four weeks apart, for each person inoculated.

In all, the United States has options to buy up to 300 million doses of those vaccines, Azar said, plus hundreds of millions more doses of vaccines yet to receive approval, including some single-dose drugs.

The United States could have a surplus supply of vaccines in the future, if all the vaccines it has secured are authorized for use, Azar said, which could eventually benefit other countries.

The Trump administration was also in talks to secure additional antibody treatment doses from Regeneron Pharmaceuticals Inc and Eli Lilly and Co, Operation Warp Speed chief adviser Moncef Slaoui told the same conference call.
