They exposed the blood samples to common germs like E. coli bacteria and the flu virus and measured the immune response. It had nearly the same impact on immune response as important factors such as age or sex. The innate immune response is the general way the skin, mucous membranes, immune system cells and proteins fights germs. The experiment was done in blood samples in the lab, but the immune system may react differently in real life. Those mice cleared a bacterial infection less efficiently and with a less-robust immune response than mice that weren’t exposed.

The two Africa-based vaccine manufacturers are receiving $5 million each in funding from the foundation, while another $10 million is earmarked for other companies that have not yet been named. Political Cartoons View All 1202 ImagesThe mRNA vaccine technology came to the forefront with the production of COVID-19 vaccines made by Pfizer and Moderna. Those COVID-19 mRNA vaccines were fast-tracked through the regulatory process and granted emergency use authorization. The new vaccines under development in Africa face a far longer development timeline — anywhere from three to seven years. It has spent billions of dollars to vaccinate against polio, treat and prevent malaria and HIV and more recently advance vaccines for diseases like cholera.

Bat viruses have been the source of multiple health crises besides those related to coronaviruses, including recent outbreaks of Ebola, Nipah, and Marburg. Partners in risk The total area at high risk for bat viruses to infect humans more than doubled in size in Laos between 2002 and 2020. The animals, known to be susceptible to bat viruses, included raccoon dogs, bamboo rats and porcupines. As China boomed in recent decades, global demand for rubber also skyrocketed, leading to further development and deforestation here. Already, scientists have found local bats bearing viruses closely related to those responsible for the 2003 SARS and COVID-19 pandemics.
Bat lands worldwide are besieged, seeding risk of a new pandemic

This collision – bats and humans competing for resources on territory long the domain of the bats – could trigger the next pandemic. As people destroy bat habitats worldwide, they are unwittingly helping bat-borne viruses mutate, multiply, and infect other species, including homo sapiens. For millennia, bat viruses lurked across the forests of West Africa and in other undisturbed parts of the world but posed little threat to humanity. They’re potent proliferators: Some roost tightly together and in close quarters with other bat species. Each of the bat viruses analyzed by Reuters has epidemic potential, according to the World Health Organization.
Viruses in Cambodian bird flu cases identified as endemic clade

Feb 26 (Reuters) - The viruses that infected two people in Cambodia with H5N1 avian influenza have been identified as an endemic clade of bird flu circulating in the country, the U.S. Centers for Disease Control and Prevention (CDC) said. The cases reported last week had raised concerns they were caused by a new strain of H5N1, clade 2.3.4.4b, which emerged in 2020 and has caused record numbers of deaths among wild birds and domestic poultry in recent months. An investigation into the source and to detect any additional cases is ongoing, the CDC said, adding that so far there had been no indication of person-to-person spread. The World Health Organization said it is working with Cambodian authorities following the cases, describing the situation as worrying due to the recent rise in cases in birds and mammals.
