More than a dozen states have sued the Trump administration over its rollback of vaccine recommendations for children, calling the move an illegal threat to public health. The states on Tuesday argue that the Centres for Disease Control and Prevention put children's lives at risk when it announced last month that it would stop recommending all children get immunised against the flu, rotavirus, hepatitis A, hepatitis B, some forms of meningitis and RSV. Under the new guidance, which was met with criticism from medical experts, protections against those diseases are recommended only for certain groups deemed high risk or when doctors recommend them in what's called "shared decision-making." The new vaccine recommendations ignore long-standing medical guidance and will make states have to spend more to protect against outbreaks, the states, including Arizona and California, said. "The health and safety of children across the country is not a political issue," Arizona Attorney General

A new study shows that both our genes and life experiences leave lasting epigenetic marks on immune cells, shaping how differently we respond to the same virus

The review highlights how changes in immune cells inside tumours may speed up breast cancer spread and could shape future treatment strategies

Often symptomless, chronic inflammation keeps the immune system switched on, delaying diagnosis and worsening long-term autoimmune damage

From anxiety-like symptoms to heart palpitations, Graves' disease often goes unnoticed. Doctors explain what modern triggers may be responsible

As hospitals strengthen neurological care after GBS cases in Pune and MP, doctors explain the symptoms, triggers and treatments that can prevent severe complications

The 2025 Nobel in Medicine honours the discovery of regulatory T-cells, which are the body's immune 'security guards' that could transform treatment of autoimmune diseases and cancer

Prolonged illnesses like cancer and chronic infections often leave the immune system in a state of exhaustion, where its frontline defenders - T cells - lose their ability to function effectively

Getting the second Covid jab on the same arm as the first one or on the opposite arm could influence the body's immune response generated against the SARS-CoV-2 virus, new research from Germany says. Those who got jabbed on the same side, or ipsilaterally, generated more antibodies against the Covid-causing pathogen than those who got jabbed on the opposite side, or contralaterally, the study from Saarland University and other German institutes found. Further, median levels of infection-fighting CD8 T-cells generated in response to the spike-protein of the pathogen were found to be significantly lower in those contralaterally vaccinated. CD8 T-cells destroy virus-infected cells and render protection against severe disease. Consequently, after contralateral vaccination, fewer individuals (43 per cent) were found to have detectable levels of CD8 T-cells than after ipsilateral vaccination (67 per cent), the study published in the journal eBioMedicine said. Individual doses of two-dose

Guillain-Barre Syndrome (GBS) is a rare disorder that affects the immune system causing it to attack the nerves of the body

Human body's natural process of removing old and damaged cell parts could be harnessed to treat infections like tuberculosis (TB), reducing reliance on antibiotics, according to a new study. Researchers at the Francis Crick Institute, UK, investigated genes important for bacteria to evade autophagy, a self-destruction mechanism cells resort to when stressed. Their study is published in Nature Microbiology. According to the study, from induced pluripotent stem cells, a kind of specialist stem cells and are able to become any cell type in the body, the scientists engineered macrophages, or human immune cells. Following this, they disabled these macrophages from performing autophagy using genome editing tools. The cells were then infected with Mycobacterium tuberculosis, bacteria causing TB. The scientists found that the infection took hold, replicating more within the edited macrophages and causing mass host-cell death. The results evidence the role of autophagy in controlling ...
