Kennedy’s Comments On Novavax Delay Scientifically, Legally Inaccurate, Experts Say The HHS Secretary publicly acknowledged the unusual delay of Novavax's COVID-19 vaccine licensure, but his justification was neither scientifically accurate nor legally justifiable, experts said.

Kennedy’s comments on the Novavax covid vaccine approval delay aren’t scientifically accurate and don’t conform with FDA law, experts said.

A Second Child Dies of Measles in Texas It is the second confirmed measles death in the U.S. in a decade. If the outbreak continues at the current pace, the nation may lose its β€œelimination” status.

Kevin Hassett, Director of the National Economic Council of the United States: tariffs were not introduced for Russia because it's in the middle of peace negotiations.

(By the way, Ukraine is subject to President Trump's tariffs).

A hundred years ago, the average life expectancy was <50. Today, it is ~80.

What made the difference? Public Health. Public health, however, is not some magic entity happening in a vacuum - it requires people.

Without those people, there can be no Public Health. That serves no one.

Wake up.

Peter Marks from the FDA resigns

"it has become clear that truth and transparency are not desired by the Secretary [RFK Jr regarding vaccines], but rather he wishes subservient confirmation of his misinformation and lies."

America will be less healthy & less safe as a result of Peter Marks' forced resignation from FDA. He & FDA protected us from people who enrich themselves selling snake oil: unproven stem cell therapies, vaccine alternatives, other fake treatments. Thank you for all you did for public health Peter.

Russia kidnaps Ukrainian children and gives them to Russians to erase their heritage and demoralize Ukraine. Over 20,000 so far. And the US just stopped helping track these kids and likely deleted the database of all the research. Pure evil, right maga?

Bioscience Funding Confusion Threatens U.S. Innovation β€˜With the current turmoil, China could surpass the U.S. in the near future,’ Nobel Prize winner David Baker warns.

Another outstanding story of the real-world impact of the short-sighted cuts to NIH and other federal support for the best scientific research infrastructure in the world.

Contribution of vaccination to improved survival and health: modelling 50 years of the Expanded Programme on Immunization Since 1974 substantial gains in childhood survival have occurred in every global region. We estimate that EPI has provided the single greatest contribution to improved infant survival over the past 50...

Nothing will kill more children than the ongoing decimation of CDC, NIH, and USAID work to lift vaccine uptake in the US and world.

Child survival rose 75% in the last 50 years. Vaccines account for 40% of that. Measles vax alone was 60% of the benefit. www.thelancet.com/journals/lan...

Congratulations to Liming Du, now on the faculty @iShandong university, for discovering that increased interferon levels in aging bone marrow remodels the stromal microenvironment around arterioles and contributes to the decline in lymphopoiesis.

House cuts to NIH (to fund billionaires) would cut the Cures Act (passed with bipartisan support) by ~$300 million or 70%. Scientific loss includes cancer research, adult stem cell research, brain/dementia research, and a critical data collection project to study rare diseases, among other topics.

This is the Attorney General, the nation’s chief law enforcement officer. She goes on Fox News every day. Every single day. Spewing MAGA talking points. I wonder how MAGA would feel if the next AG under a Democratic president went on MSNBC every day & spewed partisan Dem stuff.

At tonight’s State of the Union, Trump will have one goal: to distract.

His policies are wreaking havoc on the economy and upending American lives, and he will lie, blame, and distract to avoid any bit of responsibility. Don’t fall for it.

NIH has been intentionally holding up grants including non-competitive renewals.

This β€œpause” should be evident in Reporter data over the next week, but I posted about the beginning of it yesterday.

This is now ending because β€œNIH” has put a process in place to evaluate grants.
