1/ Heart-related deaths🫀💀 spiked in 2020
*** BEFORE*** we had COVID vaccines.

Why?

COVID causes heart disease/death!

with @CBSNews' @vladduthiersCBS & @megoliver

2/ In 2020, the US experienced the HIGHEST number of cardiovascular deaths 🫀💀 in almost 20 years.

More people died from cardiovascular-related causes in 2020, the first year of the COVID pandemic than in any year since 2003.
3/ COVID can cause heart attacks🫀 & heart failure.

People of ALL ages were affected, NOT just the elderly.
4/ The largest increases in cardiovascular deaths were seen among Black, Hispanic, & Asian people.

Remember that COVID hit communities of color harder than others, especially early in the pandemic.
5/ How does COVID cause heart disease?

COVID causes clots in blood vessels.

When a clot blocks the blood vessels that feed the heart muscle🫀, you get a heart attack.

When a clot blocks the blood vessels that feed the brain🧠, you have a stroke.
6/ COVID can also infect the heart muscle🫀, what we call myocarditis.

When COVID infects the heart muscle, it weakens it & can lead to heart failure.
7/ And then there are people who had heart🫀 disease or heart symptoms,
who were afraid to go to the hospital🏥 or see a doctor👩🏾‍⚕️🩺,
& who's condition got worse.
8/ People who have heart🫀disease & risk factors for heart disease,
like obesity & high blood pressure,
tend to have more severe disease when they get COVID,
& that creates a feedback loop:
heart disease leading to more severe COVID leading to more damage to the heart.
9/ NYC🍎 was the epicenter of the COVID pandemic in March/April 2020.

We had a huge COVID surge⬆️.

Then in August, we saw a spike⬆️ in heart 🫀failure cases.

That's because people who got COVID back in the spring & who suffered heart damage went on to develop heart failure.
10/ COVID vaccines ⬇️⬇️⬇️ the risk of severe COVID.

Severe COVID includes heart🫀attacks, myocarditis & heart failure from COVID.

Can COVID vaccines cause myocarditis?
Yes, VERY VERY VERY rarely.

But the risk of myocarditis from COVID is MUCH MUCH MUCH higher.

1/ Why the confusion over COVID vaccines now?

What’s changed isn’t the science. It’s the process.

Policy is increasingly announced by officials online & outside the usual evidence review, creating mixed messages for families.

on @CBSMornings with @edokeefe @TheKellyOGrady
2/ Normally, FDA reviews products, then CDC’s vaccine advisers (ACIP) publicly weigh evidence & vote.

CDC adopts guidance, which insurers & programs like Medicaid, the Children's Vaccine Program (CHIP), & Vaccines for Children follow.

That process has been corrupted.
3/ This season, the FDA narrowed COVID vaccine approvals:
🔹People 65+
🔹People 6m to 64y if they have at least one risk factor for severe COVID (including pregnancy)

Off-label use:
🔹Healthy people 6m to 64y in consultation with your doctor

1/ It’s been a chaotic week at the CDC.

The director was fired less than a month into her tenure, four senior leaders resigned in protest, & the agency is still reeling from a shooting at its Atlanta HQ.

on @CBSNews @FaceTheNation with @EdOKeefe
2/ These aren’t just headlines about “palace intrigue.”

What’s unraveling is the basic machinery that keeps Americans safe: vaccines, outbreak detection, lab guidance, and expert support for state health departments.
3/ Within hours of the firing of CDC Director Dr. Susan Monarez’s, 3 leaders—responsible for vaccine safety, respiratory diseases, & the chief medical officer role—resigned.

Earlier that week, CDC’s head of data systems also stepped down.

More departures are expected.

1/ After the shooting at CDC earlier this month, employees sent a blunt letter to HHS Secretary Robert F. Kennedy Jr.

They said that instead of standing with them, RFK Jr. is spreading conspiracy theories about the CDC & their work.

on @CBSEveningNews with @jdickerson
2/ They called this dangerous & made 3 requests:
🔹Stop spreading inaccurate health info
🔹Affirm CDC’s scientific integrity
🔹Guarantee safety of the HHS workforce

savehhs.org/letter/hhs-sta…
3/ Since the shooting, CDC staff say they’ve been harassed with phone calls.

Callers mockingly ask, “Are you resilient?” before playing gunfire sounds, echoing CDC’s own post-shooting messaging.

1/ For the first time in decades, US pediatricians have released their own vaccine schedule, separate from the CDC.

Why? Because they no longer trust the government’s process.

Here’s what parents need to know. 🧵
on @CBSEveningNews with @jdickerson
2/ Earlier this year, the CDC’s vaccine advisory committee was overhauled.

All 17 experts were dismissed & replaced with just 7 appointees—several with a history of spreading vaccine misinformation or skepticism.
3/ The Vaccine Integrity Project was established to fill the void & brings together many of top vaccine experts.

Today, the Vaccine Integrity Project reviewed the most up-to-date science on the safety & effectiveness of flu, RSV & COVID vaccines.

1/ New CDC data show just how much ultra-processed foods dominate U.S. diets.

Americans get ~55% of daily calories from UPFs.

Almost 2/3 of what kids & teens eat is ultra-processed.

on @CBSEveningNews with @TheKellyOGrady
2/ The biggest sources?

Sandwiches, sweet bakery goods, packaged snacks, & sugary drinks. 🥪🍩🥤
3/ So why does this matter?

Because a major new U.K. clinical trial—the largest & longest yet—found that even “improved” UPFs can’t match the benefits of minimally processed meals. 🍎🥗

1/@DeionSanders’ bladder cancer diagnosis was caught by chance, during a CT scan for an unrelated issue.

with @nateburleson @vladduthiersCBS @AdrianaDiaz on @CBSMornings
2/ Most bladder cancers are found when people notice blood🩸 in their urine, the hallmark symptom.

But early cancers can be silent, as in Sanders’ case.
3/ His scans, done for blood clots, ended up saving his life.

Even though his cancer was high-grade, it hadn’t invaded the bladder muscle.

That allowed surgeons to remove his bladder & cure him.
