COVID-19 News

Here are the news, press releases and videos from the Institut Pasteur (Paris), which was mobilized as soon as the first cases were announced, following the declaration of the epidemic by the Chinese authorities. For the record, an epidemic of pneumonia of viral appearance and of unknown etiology emerged in the city of Wuhan (Hubei province, China) in December 2019. On January 9, 2020, the discovery of a new coronavirus (first called 2019-nCoV, then SARS-CoV-2) was officially announced by the Chinese health authorities and the World Health Organization (WHO). This coronavirus is the agent responsible for the new infectious respiratory disease called Covid-19 (CoronaVIrus Disease 2019).

COVID-19: analysis of the sensitivity of the UK (B.1.1.7) and South African (B.1.351) variants to SARS-CoV-2 neutralizing antibodies
The B.1.1.7 and B.1.351 variants of SARS-CoV-2 were first detected in the UK and South Africa respectively, and have since spread to many other countries. Scientists from the Institut Pasteur joined forces with Orléans Regional Hospital, Tours University Hospital, Créteil Intercommunal Hospital, Strasbourg University Hospital and Georges Pompidou European Hospital to study the sensitivity of these two variants to neutralizing antibodies present in the serum samples of people who have been vaccinated or previously infected with SARS-CoV-2.

SARS-CoV-2 variants of interest can infect mice: host range extended
SARS-CoV-2, the virus responsible for COVID-19, is capable of infecting some species, while others are naturally resistant to it. This determines the "host range" of the virus. The SARS-CoV-2 host range includes humans, non-human primates, hamsters, mink and cats. Since the start of the pandemic, mice and rats had proven to be resistant to SARS-CoV-2, because their ACE2 receptor, which allows the virus to enter cells, is very different from the human receptor.

Comment: The tortuous path to ending the Covid-19 pandemic
The COVID-19 pandemic has devastated health-care systems, shut down schools and communities, and plunged the world into an economic recession. While 2020 was a challenging year, 2021 looks to be difficult with the emergence of multiple variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The race to vaccinate the world will need to respond to the pathogen's constant evolution to evade immunity. What marks the path to the end of this pandemic?

COVID-19: progress update on the Institut Pasteur's scientific response and vaccine candidate research programs
Since early 2020, the Institut Pasteur has been engaged in research in several of its areas of scientific expertise, including virology, diagnostics, pathophysiology, epidemiology, modeling, therapeutic research and vaccine research. A number of research programs to find a vaccine for SARS-CoV-2, the virus responsible for the COVID-19 epidemic, are under way. In light of the intermediate results of its Phase I clinical trial, the Institut Pasteur is stopping development of one of its vaccine candidates, the vaccine based on the measles vaccine virus.

COVID-19: neutralizing immune response lasts longer in women than in men
As part of the SEROCoV-HUS study, teams from Strasbourg University Hospital and the Institut Pasteur monitored 308 hospital staff who had previously contracted a mild form of SARS-CoV-2. The scientists demonstrated that neutralizing antibodies could be detected in 84% of them up to 6 months after infection, but that the level fell more quickly in men than in women. These results seem to suggest that immunity lasts longer in women than in men.

Operation and reliability of RT-PCR tests in the detection of SARS-CoV-2
The National Reference Center (CNR) for Respiratory Viruses at the Institut Pasteur specializes in viruses such as influenza and bronchiolitis in infants. As an expert center in France, the CNR is responsible for monitoring cases of respiratory infections and for epidemic surveillance. When a new virus emerges, like the novel coronavirus in China, the CNR's task is to do everything it can to detect the novel pathogen.

Editorial: How can we reach a level of herd immunity that will protect us from COVID-19?
Epidemiological theory teaches us that a microbial agent introduced into a population stops circulating when the proportion of the population that is immune to that agent is higher than or equal to 1-1/R0, where R0 is the much-discussed reproduction rate, the number of secondary cases generated by each infected person in a non-immune population in the absence of control measures.

Innate immunity and fusion of cells infected with SARS-CoV-2
Innate immunity is the fastest-acting component of the immune system, but so far little is known about its role during infection with SARS-CoV-2. A few hours after an infection, the body emits an alarm signal, interferon, enabling cells that have not yet been infected to produce antiviral proteins. This phenomenon occurs well before the production of neutralizing antibodies. Scientists from the Institut Pasteur and the CNRS set out to investigate the consequences of SARS-CoV-2 infection for cell function and the antiviral role of innate immunity.

COVID-19: no cross-protective immunity conferred by other coronaviruses in children
Every winter, seasonal coronaviruses are responsible for repeated colds and bronchitis from early childhood onwards. The question of whether the four seasonal coronaviruses can confer cross-protective immunity for COVID-19 was recently raised when it was demonstrated that some individuals had antibodies and immunity cells recognizing the SARS-CoV-2 virus before it was in active circulation. The existence of such immunity would have a major impact on our understanding of how the outbreak is likely to develop.
