U.S. officials reviewing possibility Moderna vaccine is linked to higher risk of uncommon side effect than previously thought
Federal health officials are investigating emerging reports that the Moderna coronavirus vaccine may be associated with a higher risk of a heart condition called myocarditis in younger adults than previously believed, according to two people familiar with the review who emphasized the side effect still probably remains uncommon.
In a Handful of States, Early Data Hint at a Rise in Breakthrough Infections
Since Americans first began rolling up their sleeves for coronavirus vaccines, health officials have said that those who are immunized are very unlikely to become infected, or to suffer serious illness or death. But preliminary data from seven states hint that the arrival of the Delta variant in July may have altered the calculus. Breakthrough infections are also likely to be most severe among older adults or those who have conditions like obesity or diabetes.

Five Koreans die after AstraZeneca vaccination
Five South Koreans have died in the last two days after receiving the Covid-19 vaccine produced by AstraZeneca, sparking a presidential response and contributed to rising global concerns about the dose. According to local media reports, the five who died – two on Wednesday and three on Thursday – all had significant pre-existing medical conditions.
Covid-Linked Syndrome in Children Is Growing and Cases Are More Severe
Doctors across the country have been seeing a striking increase in the number of young people with the condition Braden had, which is called Multisystem Inflammatory Syndrome in Children or MIS-C. Even more worrisome, they say, is that more patients are now very sick than during the first wave of cases, which alarmed doctors and parents around the world last spring.

Covid-19 Data in the US Is an ‘Information Catastrophe’
“Every health system, every public health department, every jurisdiction really has their own ways of going about things,” says Caitlin Rivers, a senior scholar at the Johns Hopkins Center for Health Security. “It's very difficult to get an accurate and timely and geographically resolved picture of what's happening in the US, because there's such a jumble of data.”

Three-Quarters of Recovered Coronavirus Patients Have Heart Damage
Of the 100 COVID-19 patients, 78 had structural changes to their hearts. Within that group, 76 had a biomarker that is typically found in patients who had a heart attack, and 60 had heart inflammation, called myocarditis. The patients were all “mostly healthy … prior to their illness,” the researchers said.

Not just the lungs: Covid-19 attacks like no other ‘respiratory’ virus
As the pandemic grew from an outbreak affecting thousands in Wuhan, China, to some 10 million cases and 500,000 deaths globally as of late June, the list of symptoms has also exploded. The Centers for Disease Control and Prevention constantly scrambled to update its list in an effort to help clinicians identify likely cases.

Bars, Strip Clubs and Churches: U.S. Virus Outbreaks Enter Unwieldy Phase
New known virus cases were on the rise in 23 states on Monday as the outlook worsened across much of the nation’s South and West. Hospitalizations for the coronavirus reached their highest levels yet in the pandemic in Arizona and Texas, and Missouri reported its highest single-day case totals over the weekend.

Coronavirus: why it’s dangerous to blindly ‘follow the science’ when there’s no consensus yet
In the face of the virus emergency, research standards have been relaxed to encourage faster publication and mistakes become inevitable. This is risky. Ultimately, if expert advice on the pandemic turns out to be wrong, it will have dire consequences for how reliable scientific evidence is treated in other policy areas, such as climate change.

Genes May Leave Some People More Vulnerable to Severe Covid-19
Variations at two spots in the human genome are associated with an increased risk of respiratory failure in patients with Covid-19, the researchers found. One of these spots includes the gene that determines blood types. Having Type A blood was linked to a 50 percent increase in the likelihood that a patient would need to get oxygen or to go on a ventilator, according to the new study.

COVID-19 Risks to People With Asthma Much Lower Than Expected
Several months into the pandemic, medical experts say that Asthma hasn't been a significant risk factor. Even though CDC recommended at the beginning of the pandemic that COVID-19 patients should not be treated with corticosteroids, because steroids increase the need for ventilation, length of illness and chance of dying, this did not apply to people who are already on steroids for underlying conditions.
COVID-19’s Toll on the Heart
Other viruses can affect the heart, but experts say that COVID-19 can cause cardiac complications that are a major cause for concern, especially among those with preexisting heart disease. Although experts don't yet have conclusive data on the percentage of patients who have heart damage as a result of COVID-19 infections, estimates run as high as 25 or 30 percent.
Coronavirus: Immunity passports ‘could increase virus spread’
WHO says governments should not issue so-called immunity passports" as a way of easing lockdowns. No evidence people who develop antibodies after recovering are protected against a second infection. WHO warns that such move could actually increase the spread of the virus transmission. People who assumed they were immune could stop taking precautions.

Obesity Linked to Severe Coronavirus Disease, Especially for Younger Patients
Obesity may be one of the most important predictors of severe coronavirus illness, new studies say. It’s an alarming finding for the United States, which has one of the highest obesity rates in the world.Some 42 percent of American adults — nearly 80 million people — live with obesity. That is a prevalence rate far exceeding those of other countries hit hard by the coronavirus, like China and Italy.

Does the amount of virus you are exposed to determine how sick you’ll get?
Is the initial dose of SARS-CoV-2 (the virus that causes COVID-19) related to the disease severity? At the moment, we just don't know. The only way to answer this question definitively is with "experimental challenge studies", which involves intentionally infecting healthy volunteers in order to study diseases and their treatments.
