Washington (AFP) - US officials on Thursday reported the country's third human case of bird flu linked to the current outbreak of the virus in dairy cattle. The Michigan farm worker is the second person sickened by the disease in the Midwestern state, following a first case in Texas in April. The Centers for Disease Control and Prevention (CDC) said in a statement all three cases were spread from cows to humans, as opposed to human-to-human, which would be more concerning. But it added it was the first case "to report more typical symptoms of acute respiratory illness associated with influenza...

Washington (AFP) - Mice fed raw cow's milk infected with bird flu experienced high levels of the virus in their lungs, according to a study published Friday that suggests risk to humans who consume the drink. Over the past few years, a highly pathogenic avian influenza virus called HPAI H5N1 has spread to infect more than 50 animal species, including, from March, dairy cattle in the United States. To date, 52 herds across the country have been affected, with two human infections involving farm workers who developed mild symptoms, including pink eye. In the new study, published in the New Engl...

Washington (AFP) - A second case of bird flu has been found in a human, US health authorities announced Wednesday, less then two months after the first one as an outbreak of the disease circulates widely among dairy cows. Both individuals infected with the virus called H5N1 -- the first in Texas, the second in Michigan -- were dairy farm workers who suffered only minor symptoms and have recovered, according to authorities. Despite the second infection, the US Centers for Disease Control and Prevention said its risk assessment for the general public remained "low," but it did suggest it expects...

Washington (AFP) - A person in the US state of Texas is recovering from bird flu after being exposed to dairy cattle, officials said Monday amid growing concern over the current global strain of the virus as it spreads to new species. It is only the second case of a human testing positive for bird flu in the country, and comes after the infection sickened herds that were apparently exposed to wild birds in Texas, Kansas and other states over the past week. "The patient reported eye redness (consistent with conjunctivitis), as their only symptom, and is recovering," said the Centers for Disease...

Washington (AFP) - A person in the United States is recovering from bird flu after being exposed to dairy cattle, officials said Monday amid rising concern over the current global strain of the virus. It is only the second case of a human testing positive for bird flu in the country, and comes after the infection sickened herds in Texas, Kansas and several other states over the past week. "The patient reported eye redness (consistent with conjunctivitis), as their only symptom, and is recovering," said the Centers for Disease. They were told to isolate and are being treated with the antiviral...

Washington (AFP) - US biotech company Moderna said Thursday it had mixed results from a large-scale trial of its mRNA flu shot, based on the same technology used in its successful Covid-19 vaccine. Moderna's experimental mRNA-1010 flu shot is "quadrivalent," meaning it targets four strains of flu: A/H1N1, A/H3N2, B/Yamagata and B/Victoria -- selected based on recommendations by the World Health Organization (WHO). The Massachusetts-based company said that its flu shot generated an immune response against influenza A strains that was equal or superior to that of already licensed vaccines. Howev...

Washington (AFP) - US biotech company Moderna on Friday announced promising data from an early-stage human trial of its mRNA flu shot, based on the same technology used in its successful Covid-19 vaccine. The experimental flu shot was found to be safe, and successfully evoked high levels of antibodies in 180 people at all dosage levels, in both younger and older adults. "Even before the Covid-19 pandemic, approximately three million people died each year due to respiratory infections, and many more are hospitalized or become ill as a result of these viruses," said Moderna CEO Stephane Bancel ...

Washington (AFP) - US pharmaceutical company Pfizer said Monday it had begun a clinical trial to test an influenza vaccine designed with the same mRNA technology behind its successful Covid-19 shot. The idea is to improve on the current generation of flu vaccines that have an efficacy of 40-60 percent against a disease that can cause up to 650,000 deaths a year. "The Covid-19 pandemic allowed us to deliver on the immense scientific opportunity of mRNA," Kathrin Jansen, head of vaccine research at Pfizer, said in a statement. "Influenza remains an area where we see a need for vaccines which cou...

Washington (AFP) - US biotech firm Moderna said Wednesday it had dosed its first participants in a human study of an mRNA vaccine that targets multiple strains of influenza. The company intends to recruit 180 adults in the United States for the Phase 1/2 portion of the trial to evaluate the safety and strength of immune response to the shot, called mRNA-1010. It is based on the same messenger ribonucleic (mRNA) technology deployed in Moderna's Covid-19 shot, which is more than 90 percent effective, and if the trial proves successful, it could lead to a new generation of more protective flu vac...

Washington (AFP) - US biotech firm Novavax on Monday said it had positive results from preclinical studies of a shot combining its influenza and Covid vaccine candidates. The company said a study, which it has posted to a preprint server and will now undergo peer review, showed that the shot produced strong levels of antibodies against both diseases in ferrets and hamsters. "Despite low rates during the Covid-19 pandemic, influenza remains a significant risk to global public health and the need for versatile, more effective vaccines is as important as ever, including against the flu," said Gre...
