Changes to the Alberta government’s COVID vaccination plan this year mean many Albertans are facing long waitlists and a hefty bill to get their shot.
With the government-run program only offered through public health clinics and many of those clinics experiencing long waits, some Albertans are choosing instead to go to their local pharmacist to get immunized — as they have done in previous years.
Comments closedThe risk of long COVID was 36% lower in adolescents vaccinated within 6 months before their first infection than in their unvaccinated peers, suggests an analysis of US Researching COVID to Enhance Recovery (RECOVER) trial data published late last week in Vaccine.
The study, led by Massachusetts General Hospital researchers, involved 724 adolescents aged 12 to 17 years who were vaccinated against COVID-19 within the previous 6 months and 507 unvaccinated youth matched on sex, symptom onset, and enrollment date.
Comments closedThe risk of a heart attack triples within the first few weeks after a Covid-19 infection, the study suggested, and quadruples in the month after a flu infection. The study, published Wednesday in the Journal of the American Heart Association, was a large review and analysis of existing research.
“It endorses a general idea that we’ve been thinking about and talking about for the past several years — that infections are generally not benign,” said Dr. Ziyad Al-Aly, a senior clinical epidemiologist at Washington University in St. Louis, who was not involved in the study.
Comments closedThe updated 2024-25 COVID-19 vaccines provided 57% protection against hospitalization and death, although their effectiveness waned over time, according to a study yesterday in JAMA Internal Medicine.
The study assessed effectiveness against infection, emergency department (ED) visits, and hospitalization. Protection against infection and ED visits was 45%.
The study was based on outcomes seen among Nebraskan residents during the 2024-25 respiratory virus season and used hospital discharge data from member hospitals of the Nebraska Hospital Association and data from death certificates from the Nebraska Office of Vital Records.
Comments closedThe innovative messenger RNA (mRNA) vaccines that thwarted the ravages of COVID-19 may also help fight tumors in cancer patients, according to a new analysis of medical records and studies in mice.
People with cancer who coincidentally received the mRNA shots before starting drugs designed to unleash the immune system against tumors lived significantly longer than those who didn’t get vaccinated, a research team announced yesterday at the European Society for Medical Oncology Congress in Berlin. Laboratory experiments by the group suggest the vaccines rev up the immune system, making even stubborn tumors more susceptible to treatment.
Comments closedWhen a public building catches fire, its built-in systems automatically respond: Smoke alarms blare, sprinklers kick on, and occupants quickly evacuate.
But what if the life-threatening danger isn’t fire but invisible airborne contaminants that can make occupants sick? Could a similar smart-building system monitor and improve the quality of the air indoors, where Americans spend 90 percent of their time?
With a contract for up to $40 million from the Advanced Research Projects Agency for Health (ARPA-H), an ambitious multi-institutional research team led by Virginia Tech and including researchers at the University of California, Davis, aims to create just such a system.
Comments closedFederal health officials are examining the feasibility of taking aluminum salts out of vaccines, a prospect that vaccine experts said would wipe out about half of the nation’s supply of childhood inoculations and affect shots that protect against whooping cough, polio and deadly flu.
The review at the Food and Drug Administration began after President Trump listed aluminum in vaccines as harmful during a press briefing about the unproven link between Tylenol and autism.
Aluminum salts have been in vaccines since the 1920s and are added to enhance the immune-stimulating effect against the virus or bacteria covered by the inoculation. Robert F. Kennedy Jr., the nation’s health secretary, has been a longtime critic of aluminum in vaccines, which he has suggested is linked to autism.
Vaccine experts said the tiny amount of aluminum salts in vaccines — often measured in the one-millionth of a gram — has a long track record of safety and is essential to generating lasting immunity from disease. Developing vaccines without aluminum salts, they said, would require an entirely new formulation from scratch.
Comments closedLate Friday night more than 1,000 employees of the Centers for Disease Control and Prevention (CDC) were sent an email saying they had been let go due to reduction-in-force (RIF) efforts at the end of the second week of the federal government shutdown.
Some, however, were mistakenly fired and were rehired the next day, according to sources close to the situation.
Comments closedThe Trump administration on Saturday raced to rescind layoffs of hundreds of scientists at the Centers for Disease Control and Prevention who were mistakenly fired on Friday night in what appeared to be a substantial procedural lapse.
Among those wrongly dismissed were the top two leaders of the federal measles response team, those working to contain Ebola in the Democratic Republic of Congo, members of the Epidemic Intelligence Service, and the team that assembles the C.D.C.’s vaunted scientific journal, The Morbidity and Mortality Weekly Report.
After The New York Times reported the dismissals, two federal health officials said on Saturday that many of those workers were being brought back. The officials spoke anonymously in order to disclose internal discussions.
Comments closedDozens of employees at the Centers for Disease Control and Prevention — including “disease detectives,” high-ranking scientists and the entire Washington office — were notified late Friday that they were losing their jobs as part of the Trump administration’s latest round of federal layoffs.
It was unclear on Friday how many C.D.C. workers were affected. But it was the latest blow to an agency that has been wracked by mass resignations, a shooting at its Atlanta headquarters in August and the firing of its director under pressure from Health Secretary Robert F. Kennedy Jr.
Layoff notices landed in the email inboxes of C.D.C. employees shortly before 9 p.m. Eastern time on Friday, notifying employees that their duties had been deemed unnecessary or “virtually identical” to those being performed elsewhere in the agency. Scientists, including leaders, in offices addressing respiratory diseases, chronic diseases, injury prevention and global health were among those affected.
Comments closedThe writers are all former U.S. surgeons general.
As former U.S. surgeons general appointed by every Republican and Democratic president since George H.W. Bush, we have collectively spent decades in service as the Nation’s Doctor. We took two sacred oaths in our lifetimes: first, as physicians who swore to care for our patients and, second, as public servants who committed to protecting the health of all Americans.
Today, in keeping with those oaths, we are compelled to speak with one voice to say that the actions of Health and Human Services Secretary Robert F. Kennedy Jr. are endangering the health of the nation. Never before have we issued a joint public warning like this. But the profound, immediate and unprecedented threat that Kennedy’s policies and positions pose to the nation’s health cannot be ignored.
Comments closedA US modeling study published yesterday in JAMA Pediatrics estimates that vaccinating pregnant women against COVID-19 prevented 7,000 hospitalizations in infants and 3,000 in pregnant women from January 2024 to May 2025.
The Stanford University–led research team analyzed COVID-NET surveillance data on COVID-19 hospitalization rates in infants younger than 6 months and incidence data on pregnant women aged 18 to 49 years under a relative risk of 2.65. The aim was to estimate the health impact of vaccination during pregnancy, mainly during the second or third trimester.
Comments closedORONTO – Health Canada, the World Health Organization and Canadian autism experts say there is no evidence that taking Tylenol during pregnancy causes autism.
Health Canada and the WHO issued statements last night and this morning in response to U.S. President Donald Trump’s unproven claim linking the drug — whose generic name is acetaminophen — to the disorder.
Health Canada says acetaminophen is a “recommended treatment of pain or fever in pregnancy” and “has been used safely by millions of Canadians for decades, including during pregnancy and while breastfeeding.”
WASHINGTON (AP) — President Donald Trump on Monday used the platform of the presidency to promote unproven and in some cases discredited ties between Tylenol, vaccines and autism as his administration announced a wide-ranging effort to study the causes of the complex brain disorder.
“Don’t take Tylenol,” Trump instructed pregnant women around a dozen times during the unwieldy White House news conference, also urging mothers not to give their infants the drug, known by the generic name acetaminophen. He also fueled long-debunked claims that ingredients in vaccines or timing shots close together could contribute to rising rates of autism in the U.S., without providing any medical evidence.
Comments closedThe last meeting of the Centers for Disease Control and Prevention’s (CDC’s) Advisory Committee on Immunization Practices (ACIP) in June abandoned the use of its rigorous evidence-to-recommendation framework for making vaccine policy decisions, which structures decisions around key factors, including the balance of benefits and harms, the type or quality of evidence and health economic analyses, among other elements. The meeting also included new members making inaccurate statements about both vaccine safety and efficacy and included a presentation by a well-known anti-vaccine advocate that was filled with errors.
Now, the committee is set to include even more vaccine skeptics when it meets later this week, according to published reports, including multiple anti–COVID mRNA vaccine activists. (On Monday, the U.S. Department of Health and Human Services (HHS) confirmed five new ACIP members.)
Comments closedThe U.S. Centers for Disease Control has long been a global leader in disease tracking and evidence-based medical guidelines, but recent funding cuts and firings have caused many to wonder whether the institution is still a trusted source. CBC’s Nisha Patel breaks down how some of those changes could put Canadians at risk.
