RFK Jr cancels $500m in mRNA vaccine development in the US
The development of mRNA vaccines to target Covid-19 was critical in helping slow down the pandemic and saving millions of lives, said Paul Offit, director of the Vaccine Education Center at Children's Hospital of Philadelphia.Dr Offit told the BBC that Kennedy's move will put the US in a "more dangerous" position to respond to any potential future pandemic, since mRNA vaccines have a shorter development cycle, which is why they were able to be used to respond to the Covid pandemic. In a statement, Kennedy said his team had "reviewed the science, listened to the experts, and acted. "[T]he data show these vaccines fail to protect effectively against upper respiratory infections like COVID and flu," he said. He said the department was shifting the funding toward "safer, broader vaccine platforms that remain effective even as viruses mutate".But the mRNA vaccines are "remarkably safe" and key to helping prevent against severe infections from viruses like Covid, said Dr Offit, who invented the rotavirus vaccine. HHS said the department that runs the projects, Biomedical Advanced Research and Development Authority (BARDA), would focus on "platforms with stronger safety records and transparent clinical and manufacturing data practices".While some vaccines use an inactivated virus to trigger an immune response, mRNA vaccines work by teaching cells how to make proteins that can trigger an immune response. Moderna and Pfizer's mRNA vaccines were tested in thousands of people before being rolled out and were found to be safe and effective. Since taking office, Kennedy has taken a number of steps to transform how the nation's health department develops and regulates vaccines. In June, he fired all 17 members of a committee that issues official government recommendations on immunisations, replacing them with some people who have criticized the safety and efficacy of vaccines. He also removed the Covid vaccine from the Center for Disease Control and Prevention's recommended immunization schedule for healthy children and pregnant women.

Oral sex could increase your risk of SKIN cancer – the 3 ways to protect yourself
SCIENTISTS have discovered a new cause of skin cancer - and it's linked to oral sex. Human papillomavirus (HPV), one of the most common sexually transmitted infections (STIs) in the UK, is primarily transmitted through skin-to-skin contact during sexual activity, including oral sex. 3 3 It's previously been linked to increased risk of several cancers, including anal, head and neck, throat, penile cancer and cervical cancer. But now, US researchers say the virus could also cause a deadly form of skin cancer - squamous cell carcinoma. Scientists from the National Institutes of Health (NIH) discovered the link after a 34-year-old woman was referred to the clinic. She presented with 43 spots of the skin cancer on her face, hands and legs. But while she had surgery to remove them, as well as immunotherapy, the cancer returned. Doctors first suspected sun damage and a weak immune system, but later found the beta-HPV virus had inserted into her skin cells' DNA and was producing viral proteins, taking control of the cells. Dr Andrea Lisco, a virologist who led the study, said: "This discovery could completely change how we think about the development, and consequently the treatment, of [skin cancer] in people who have a health condition that compromises immune function. "It suggests that there may be more people out there with aggressive forms of [skin cancer] who have underlying immune defect and could benefit from treatments targeting the immune system." The woman in the case report was found to have a genetic condition that weakened her T-cells (a type of immune cell), leaving her unable to fight off the virus. Doctors treated her with a stem cell transplant to restore her immune system. Urgent health alert as most sexually active will get cancer causing virus at some point in life Three years later, her skin cancer hadn't returned, and other HPV-related complications, such as growths on her tongue and skin, had disappeared. The findings were published in the New England Journal of Medicine and are preliminary, only suggesting a potential link between HPV and skin cancer. Three ways to protect yourself from HPV The most effective way to protect yourself from HPV is to get the HPV vaccine. Additionally, practising safe sex, such as using condoms, and getting regular screenings can further reduce the risk of infection and potential health problems. HPV vaccination In the UK, the vaccine is routinely offered to children aged 12 to 13, but is also available for older individuals who may have missed it, especially those at higher risk. The vaccine is most effective when administered before the first sexual contact, but it can still provide protection even after sexual activity has begun. 3 How do you know if you have HPV? HPV doesn't usually cause any symptoms, which means most people who have it don't realise and don't have any problems. But sometimes the virus can cause painless growths or lumps around your vagina, penis or anus (known as genital warts). Genital warts appear on their own or in a group (groups of warts can look like a cauliflower. They may feel soft or firm, and be white, red, skin-coloured, or darker than the surrounding skin. Source: NHS Safe sex practices Using condoms consistently and correctly during sexual activity can significantly reduce the risk of HPV transmission, though they don't offer complete protection as HPV can affect areas not covered by the condom. Dental dams can also be used to reduce the risk of transmission during oral sex. And being in a mutually monogamous relationship with a partner who also has only had sex with you can also reduce the risk. Screening and testing Regular screenings, such as Pap tests and HPV tests, can help detect HPV and abnormal cell changes early, allowing for timely intervention and prevention of cervical cancer. Guidelines recommend starting Pap test screening at age 21 and continuing until age 65 for most women. Other ways to reduce skin cancer risk Sun protection Limit sun exposure: Avoid prolonged sun exposure, especially during peak UV hours (usually between 11am and 3pm). Seek shade when outdoors, especially during these hours. Sunscreen: Use a broad-spectrum sunscreen with an SPF of 30 or higher, and reapply it every two hours, or more frequently if swimming or sweating. Protective clothing: Wear clothing that covers your arms and legs, and choose a wide-brimmed hat to protect your face, neck and ears. Sunglasses that offer UV protection are also crucial. Skin self-exams and professional check ups Regular skin checks: Regularly examine your skin for any new moles, changes in existing moles, or any unusual spots. Pay attention to the ABCDEs of melanoma: Asymmetry, Border, Colour, Diameter, and Evolving. Dermatologist visits: Schedule regular skin exams with a dermatologist, especially if you have risk factors like a family history of skin cancer or a history of sunburns.

US Senators Wyden, Warren launch probe into UnitedHealth over alleged nursing home payments
Aug 7 (Reuters) - U.S. Senators Ron Wyden and Elizabeth Warren are launching an investigation into UnitedHealth Group (UNH.N), opens new tab related to allegations that the company secretly paid nursing homes thousands in bonuses to help slash hospital transfers for ailing residents. In a letter dated August 6 to UnitedHealth CEO Stephen Hemsley, the senators called on the healthcare conglomerate to provide detailed information about its reported incentive programming and its impact on residents. The company in July publicly confirmed it was under investigation by the U.S. Department of Justice and said it was complying with both criminal and civil requests from the federal agency over its Medicare business, a U.S. government program that covers medical costs for individuals aged 65 and older and those with disabilities. The senators have sought responses by September 8 about the company's hospitalization policies, directives related to care planning for nursing home residents enrolled in their institutional special needs plans, marketing practices related to those plans and federal oversight related to them. In May, the UK's Guardian newspaper reported the company made secret payments to nursing homes, as part of a series of cost-cutting tactics that saved the company millions, but at times risked residents' health, citing an investigation carried out by the newspaper. "Any attempt to take advantage of vulnerable nursing home residents is unacceptable, especially to pad a for-profit insurance company's revenues," the senators said in the letter. At that time, UnitedHealth had said the U.S. Department of Justice had investigated those allegations, interviewed witnesses, and obtained thousands of documents that demonstrated the significant factual inaccuracies in the allegations. UnitedHealth did not immediately respond to a Reuters request for comment when contacted on Thursday.

Tragedy as six-year-old kindergarten student dies of the flu after she was discharged from hospital
A six-year-old girl has died from the flu shortly after she was discharged from hospital, sparking an investigation. The kindergartner had presented to Sydney Children's Hospital at Randwick on August 4 and was discharged, only to be brought back by her worried father later the same day. On the second visit she was diagnosed with influenza A and discharged again. She was then taken to Northern Beaches Hospital shortly after where she died, reported The Manly Observer. Sydney Children's Hospital and Northern Beaches Hospital will conduct a joint review into the case. The matter had also been referred to the Coroner for a separate inquest. Sydney Children's Hospital said in a statement that the patient had presented at the emergency department and was discharged after she was assessed. She then returned and was discharged with 'at-home guidance' for influenza. 'Sydney Children's Hospitals Network (SCHN) has learnt the patient later tragically died. SCHN expresses our deepest condolences to the family for the loss of their child.' Northern Beaches Hospital told the publication it was 'deeply saddened by the tragic loss' and and that an independent review and coronial inquest would be conducted. Across Australia in the first half of 2025 there were more than 150,000 lab confirmed cases of influenza. Vaccine coverage for influenza sits at just 24.24 per cent nationally and 14 per cent for those under the age of 50.
