Focusing on mortality from the COVID-19 virus is no more effective than calls to wear masks and save lives, but it significantly increases people's anxiety. After conducting an experiment with over 15,000 respondents from 84 countries, an international group of researchers, including scientists from HSE, came to this conclusion. The results of the study have been published in the Affective Science journal.

In addition to finding the causes of this disease and creating medicines and vaccines, each country faced the need to develop a communication strategy that would work with its population. The problem of influencing millions of people and informing them about effective ways of fighting the COVID-19 virus rapidly became one of the important aspects of public policy in every country in the world.

From April to September 2020, researchers from 84 countries worked together on finding out which communication strategies were most effective in working with the general population during the pandemic. Which framing is more effective—a positive emphasis on the advantages of certain behaviour, or negative messages that could scare people who do not follow the safety rules? To find out the answer to this question, the researchers conducted an experiment with more than 15.000 respondents across 48 languages.

Some reports focused on the positive gains of actions such as wearing a mask, while others highlighted the potential losses that could result from not following these steps.

The survey was based on recommendations from the World Health Organization urging people to do four things: stay at home as much as possible, avoid shopping, use face masks and isolate yourself in case of contact with the virus. The questions were framed to emphasize the gains or losses: ‘Wear a mask. Save lives’ and ‘If you don't wear a mask, it can lead to people’s death.’

The results of the study showed that neither type of messages affected people's social behaviour. At the same time, information about potential losses significantly increases people’s anxiety. Moreover, the effect of anxiety on stress hormone secretion may increase with age, potentially putting older people who already face an increased risk of COVID-19 infection in an even more vulnerable position.

In order to demonstrate that the results were not dependent on the use of a specific model, method of analysis or sampling, the researchers tested them on different data pools using different statistical procedures. The researchers analysed three variants of framing and carried out 560 types of calculations on different samples. More than 80% of the models showed consistent results, which indicates the reproducibility and reliability of the results obtained for all 84 countries.

‘We found out that the framing and any culturally specific connotations do not affect the results obtained in particular countries,’ says Irina Prusova, one of the authors of the study, junior research fellow at HSE Laboratory for Psychology of Social Inequality.

The study was the first large-scale and representative cross-section of the impact of information on human behaviour during the pandemic.

According to the authors, the results obtained can help build an effective communication policy to fight the spread of COVID-19 and other epidemics.

Paper by HSE Biologists Included in the Top 5 Popular Articles of PeerJ Journal

An article by researchers from HSE University’s Faculty of Biology and Biotechnology is among the most read articles published in the PeerJ journal in 2023. In the paper, the researchers establish a link between the genetic characteristics of the human immune system and its ability to effectively resist new waves of COVID-19. PeerJ is a peer-reviewed open access scientific journal covering research in the field of biological and medical sciences. Every year the editors compile a ranking of the most popular scientific papers.

COVID-19 Mortality Highest in More Affluent Russian Regions

COVID-19 came as an unexpected challenge for humanity. Countries adopted different, sometimes diametrically opposed approaches to minimising the pandemic's impact: from hard lockdowns to no restrictions at all, as in Sweden. It was only last week that China began to relax its zero-tolerance policy. Researchers of the HSE Faculty of Economic Sciences have identified a few factors which tend to have the greatest impact on the spread of COVID-19—in Russia, such factors include ambient humidity and temperatures, population mobility, the share of internal migrants in the local population, and household incomes. The study findings are published in Population and Economics.

Acceptance of Vaccination Associated with Lower Social Media Use and Higher Trust in Government

Vaccination is generally considered an essential tool for curbing the COVID-19 pandemic. Although Russia was one of the first countries to develop a vaccine against COVID-19 and launched an immunisation campaign in 2021, its vaccination rates remained low for a long time. By October 2021, only 36% of Russian adults were vaccinated, many of whom were compelled by their employers to do so. Having examined the factors contributing to low trust in vaccination among Russians, HSE economists suggest measures to improve vaccination uptake. The paper is published in Vaccine.

Russian Researchers Assess the Power of T-Cell Immune Response to Omicron BA.1 and BA.2

Scholars from HSE University and the RAS Institute of Bioorganic Chemistry have demonstrated the efficiency of T-cell immune response against the Omicron variant of SARS-CoV-2. In approximately 90% of vaccinated Europeans, T-cell immunity was as effective against Omicron as with other variants. The results of the study were published in PeerJ.

Russian Researchers Assessed the Likelihood of Sleep Disorders after COVID-19

A team of researchers from the HSE Centre for Cognition and Decision Making and the Central State Medical Academy conducted a study on sleep disorders, mood and fatigue after COVID-19. These factors are interrelated and the researchers recommend a comprehensive approach to treat the problem effectively. The work was published in the journal Neuroscience and Behavioral Psychology.

HSE Biologists Prepare Strategy for Universal COVID Test

Russian researchers have developed a strategy to create a cheap and rapid COVID-19 test based on isothermal amplification. According to their publication in Applied Biochemistry and Microbiology, use of this strategy will make it possible to create universal test systems for any of the COVID-19 variants.
