Covid 19 mrna Vaccines...Yes/No?
- Thread starter gaiusmarius
- Start date
they aren't saying anything about it in local media, but nearly every nursing home in area has a wing closed off for Covid positive residents. local paper has stopped putting anything on front page that is not good news... to be honest, several papers in region are now doing this. ours has also been cut down in size two days a week. reality/bad news not popular. i reckon these ol' boys get all they want of that from Faux News at night. lol...
Dense would be ignoring the dangers of covid.

Possible cause of long COVID 'brain fog'
La Trobe University led research may have uncovered the cause of the neurological conditions seen in patients with long COVID, such as brain fog.The study, published in Nature Communications, provides the first indications that some of the neurological symptoms in long-COVID are being caused by amyloid clumps appearing in the brain that are similar to those that cause Alzheimer’s Disease and dementia.
Dr Nick Reynolds from La Trobe University’s Institute for Molecular Science said the research reveals similarities between the effects of COVID-19 and the early stages of neurodegenerative disease such as Alzheimer’s and Parkinson’s.
The authors cautioned that the implications of the changes were unclear and did not necessarily suggest people might have lasting damage or that the changes might profoundly affect thinking, memory or other functions.
According to Dr Reynolds, if further studies confirm that amyloid clumps are contributing towards long-COVID, then drugs which have been developed to combat Alzheimer’s and Parkinson’s may be repurposed to treat these debilitating neurological symptoms.
“It may be possible that existing drugs may be used to treat the brain fog that affects a significant portion of people who go on to experience long-COVID having been infected with SARS-CoV-2,” Dr Reynolds said.
Long COVID is marked by neurological symptoms such as memory loss, sensory confusion, severe headaches, and even stroke in up to 30 per cent of cases, which can persist for months after the infection is over. While there is evidence that the virus can enter the brain of infected people, the precise mechanisms causing these neurological symptoms are unknown.
The researchers investigated if similar amyloid clumps could be formed from fragments of protein from SARS-CoV-2. Finding two such protein fragments that readily form amyloids, called ORF6 and ORF10, and that these are highly toxic to brain cells grown in a lab.
Dr Reynolds said the findings of aggregates of SARS-Cov-2 proteins in people with long COVID may explain the condition known as “brain fog”.
“These toxic clumps of protein, or amyloid assemblies, appear to be similar to those found in Alzheimer’s disease and may be responsible for some of the neurological symptoms of long-COVID,” he said. “We suggest that aggregates of SARS-CoV-2 proteins may trigger neurological symptoms in COVID-19 that many call brain fog,” he said.

Even mild COVID raises the chance of heart attack and stroke. What to know about the risks ahead
Published: September 19, 2022 4.07pm AESTDisclosure statement
The authors do not work for, consult, own shares in or receive funding from any company or organisation that would benefit from this article, and have disclosed no relevant affiliations beyond their academic appointment.A concerning report recently published in Nature Medicine suggests even a mild case of COVID can increase the long-term risks of serious cardiovascular diseases such as stroke, heart attack and heart failure. The study highlights our limited understanding of the full consequences of COVID infection and the long-term impact of the COVID pandemic.
Australia has now reported more than 10 million cases of acute COVID infection and more than 14,000 deaths, with at least 600 million more people infected worldwide.
The immediate effects of COVID infection on the heart have been well documented, with myocarditis (inflammation of the heart muscle) an infrequent but potentially lethal complication. But myocarditis only occurs in about 40 people per million infected.
The big concern raised by this fresh study is that medium- to long-term harms on the body’s blood vessel network (the vascular system) may be much more common than that. And it could drive a new pandemic of cardiovascular disease over the coming years.

What they found
The study, led by researchers at Washington University, showed a heightened risk of future cardiovascular events among people who have recovered from COVID.The authors analysed the health records of around 150,000 US veterans, who are often studied because they are a well-documented group within a discrete health-care system. They compared the rates of cardiovascular disease in veterans who’d experienced a COVID infection against uninfected control groups that included some 10 million people.
Between 30 days and a year after recovery from COVID, survivors were 52% more likely to have a stroke, 63% more likely to have a heart attack, and 72% more likely to develop heart failure. This means that over one year, for every 1,000 people who had COVID, there would be five extra strokes, three extra heart attacks and 12 extra cases of heart failure. There was also evidence of an increased risk of serious blood clots on the lungs.
While these numbers might sound small to some, when scaled to 600 million COVID infections worldwide, the implications are enormous.
One particularly concerning finding was that while those with more severe acute COVID infections had the highest risk of a cardiovascular events over the following year, even those with a mild infection were at increased risk. And that risk was not restricted to those who’d had heart health problems before – it could affect anyone.
Necessary caution
The study was large and had many strengths. But the findings must be reviewed with a degree of caution. It was an observational study (in which researchers draw inferences from what they see in a population, rather than control variables for an experimental study). So, we can’t be certain the increased risk of heart disease or stroke was definitely caused by the COVID infection. The people infected with COVID were not identical to the people who were uninfected.That said, the researchers made statistical adjustments and could not identify another explanation for the large increases in risks seen.
It is also likely some people with asymptomatic COVID infection were accidentally included in the control groups. However, the effect of this would have been to underestimate the risks of COVID infection on cardiovascular risk.
And of course, US veterans are a very particular set of individuals (mostly older, male and white). Even if the effects of COVID on cardiovascular risk are real for them, there must be some uncertainty about whether the same effects would be seen in other populations.
COVID and hearts
The clear, but low, risk of heart disease at the time of COVID infection also provides support for a connection between COVID infection and medium- to long-term heart disease.Even before the COVID pandemic there was a well-established link between the inflammation caused by infection and the risk of heart attack.
A heart attack occurs when an artery supplying blood to the heart is blocked and the heart muscle is starved of oxygen. This usually happens when rupture of a fatty plaque in the artery causes a blood clot to form. This process is driven by inflammation in the tissues and thickening of the blood, both of which can occur with COVID, and both of which can persist long after the initial infection has resolved.
These data remind us once again of the importance of limiting the spread of the SARS-CoV-2 virus. The best way to reduce COVID-related risks is to prevent COVID infection and reduce the severity of infection. We must maintain high vaccination rates and support infection control measures such as mask wearing in high-risk situations. Ever stronger evidence of the long-term effects of COVID redoubles the importance of these efforts.
Future problems
We rightly feared the respiratory complications of COVID throughout 2020 and 2021 but only now are we appreciating the full impact of the pandemic across other body systems.
Doctors will need to view COVID infection as a new long-term risk factor for cardiovascular disease in much the same way that many other chronic inflammatory conditions such as rheumatoid arthritis are viewed now. We should advocate for fair access to heart disease prevention and treatment in all Australians, particularly those at highest risk such as First Nations people. And most importantly, as patients, we must prioritise our own heart health.
And we’ll need to remain vigilant for the effects of new strains. Over the decades to come we’ll need to plan for the enduring effects of COVID.
Even mild COVID raises the chance of heart attack and stroke. What to know about the risks ahead
The increased risks of heart attack and stroke after COVID shown in a recent study, could drive a new pandemic of heart disease over coming years.

Pot, kettle, black. I am posting information, not clutching at any straws. The vaccines were approved in countries the world over.
Have you had covid? Brain fog or shrinkage perhaps?
Keep taking the ivermectin and bleach.
I guess rhetoric is in the eye of the beholder. Everything you are accusing me of, you seem to be doing the same thing. I am posting articles that are science based at least.
I got my 4th vaccine recently. Vaccinate or not is your choice, but to discount the health problems associated with Covid is ridiculous at "this point of the game", given the evidence.

Well-known member
good for you and the jab is not safe or effective . Do you work in government ? why have you taken 4 jabs? what are the ingredients ? and why are the unvaccinated most at risk? why would i drink bleach? you sound a bit like fraudci and that don lemon guy . i'm glad you are confident in their safety and effectiveness.
