recent studies have again shown the value of using animals to find treatments and protection against Covid to treat liver disease can be repurposed to prevent SARS-CoV-2 infection, or reduce the severity of Covid confirmed in clinical trials, the drug will be valuable protection for people who do not respond well to vaccines -19 vaccine could protect infant macaque monkeys against severe disease a year after they were vaccinated Science reported that the two-dose vaccine contains a substance that enhances the immune response to

Researchers in France have used ‘organ-on-chip’ technology to shed light on the effectiveness of booster vaccines for Covid-19 and other infectious diseases. Booster vaccines can be given as an additional shot after initial vaccination to increase immunity, which The system could also respond  to different types of vaccine. Lead researcher, Lisa Chakrabarti, said: “The Covid-19 pandemic has emphasised the need for preclinical

US researchers are hopeful that research on Covid-19 can be greatly improved, using an existing strain Laboratory mice used in Covid-19 studies must often be genetically modified so that they better reflect This makes them suitable for studying Covid-19  in a way that is more relevant to the human condition It is hoped that this strain will now be an important tool in developing Covid-19 vaccines as new coronavirus Nadia Rosenthal , at JAX, said: “CAST mice stand poised to transform Covid-19 research and prepare us

A study in mice has identified ways to reduce the damage done to organs by the Covid-19 virus. Covid-19 can sometimes cause a severe immune reaction known as a cytokine storm, in which too many inflammatory , have now developed a way to replicate a cytokine storm in mice – similar to the one seen in human Covid Chugh at Rush said: “Much of what we discovered will inspire new ways of treating complications of Covid

member, the Biomedical Primate Research Centre, Netherlands, has discovered the hidden long-term effects Covid In results published in the journal Viruses, the scientists suggest that long Covid-19 symptoms could

Portugal, (an EARA member) who has spoken about his use of animals in research to develop drugs and vaccines In the Q&A, Miguel explains how his lab  uses mice to assess the effect of compounds and candidate vaccines This is particularly true for vaccine research, where the response of the immune system across multiple During the Covid-19 pandemic, Miguel was a key scientific spokesperson in the Portuguese media  and spoke extensively about the Covid-19 vaccine and vaccination – in the EARA Q&A, he also shared his top tips

& Rica, has asked a number of scientists to explain the importance of using monkeys in research on Covid "All the vaccines against Covid-19 have involved non-human primates for their pre-clinical studies”, Sanofi, as part of the development of its recombinant protein vaccine against Covid-19, used primates The article revealed that a typical vaccine evaluation study requires testing one or two doses of vaccine , on two groups: a vaccinated group and a control group (unvaccinated) using about 18-24 monkeys per

time, scientists have developed a genetically altered mouse that can get infected with the form of Covid

Around the world, scientists are working to develop a Covid-19 vaccine. The process to develop drugs and vaccines is usually long and arduous and it can take many years to identify a safe and effective vaccine. The current models used to answer questions about Covid-19 are ferrets, hamsters, pigs, mice and monkeys The next step is testing the vaccine on animals to make sure the vaccine is safe and effective.

The recent vaccine for the Ebola virus can protect people from dying, even if they already have the disease before being vaccinated, research has found. , even when the vaccine had been given just a day or two before they became ill. when Ebola did become a health threat – see this previous EARA article (this was also the case for the Covid -19 vaccine).

As concerns grow over whether animals could continue to infect humans or other animals, Covid-19 researchers In 2020, a Covid-19 outbreak on a Danish mink farm showed the potential damage of another animal species

Understanding Animal Research (UAR) has published an article dispelling the falsehoods being spread about Covid -19 vaccines and research. urban myths’, including the false claims by activist groups that animals were not an important part of Covid -19 vaccine development and safety testing. Concluding the article, author UAR’s Chris Magee, said: “We can’t stop trolls from making up vaccine
