The Great Barrington Declaration

Those who are not vulnerable should immediately be allowed to resume life as normal. Simple hygiene measures, such as hand washing and staying home when sick should be practiced by everyone to reduce the herd immunity threshold. Schools and universities should be open for in-person teaching. Extracurricular activities, such as sports, should be resumed. Young low-risk adults should work normally, rather than from home. Restaurants and other businesses should open. Arts, music, sport and other cultural activities should resume. People who are more at risk may participate if they wish, while society as a whole enjoys the protection conferred upon the vulnerable by those who have built up herd immunity.

On October 4, 2020, this declaration was authored and signed in Great Barrington, United States, by:

Dr. Martin Kulldorff, professor of medicine at Harvard University, a biostatistician, and epidemiologist with expertise in detecting and monitoring infectious disease outbreaks and vaccine safety evaluations.

Dr. Sunetra Gupta, professor at Oxford University, an epidemiologist with expertise in immunology, vaccine development, and mathematical modeling of infectious diseases.

Dr. Jay Bhattacharya, professor at Stanford University Medical School, a physician, epidemiologist, health economist, and public health policy expert focusing on infectious diseases and vulnerable populations.

Genome editing wins Nobel chemistry prize

Her work showed that tracrRNA is part of the organism’s immune defences.

This system, known as CRISPR/Cas, disarms viruses by cleaving their DNA.

In 2011, the same year she published this work, Charpentier began a collaboration with Doudna to recreate the bacterium’s genetic scissors in a test tube. They also worked on simplifying the scissors‘ molecular components so they were easier to use.

Flu Misinformation and Coronavirus Fears: My Letter to Dr. Sanjay Gupta

9. CNN assertion: Sanjay, I’ve watched your video assuring the public that getting the flu shot cannot increase one’s chances of getting the flu.

Fact: While that assertion has some meager support from a very small number of studies, the overwhelming weight of published science suggests that getting an annual flu shot can actually increase your risk of both flu and flu-like illnesses.

Only about 7 percent to 15 percent of what are called “influenza-like illnesses” are actually caused by influenza viruses. Many studies suggest the flu vaccine increases vulnerability to both flu infections and the remaining 85% -93% of non-flu respiratory infections.

A 2011 study of healthy Australian children published in the Pediatric Infectious Disease Journal found that seasonal flu shots increase the risk of flu by 73% and doubled the risk of non-flu respiratory infections.

Similarly, another 2012 randomized controlled trial published in Clinical Infectious Diseases found that influenza-vaccinated children had no significantly lessened risk from influenza and also a higher risk of infection from non-influenza viruses.

Furthermore, the flu vaccine depletes capacity to fight off future flu infections. In April 2010, a study (by Skowronek, et al) published in the journal PLoS Medicine reported the “unexpected” finding from four epidemiologic studies in Canada that receipt of the influenza vaccine for the 2008 – 2009 season, while apparently effective in reducing the risk of illness due to the seasonal flu, was associated with an increased risk of illness due to the pandemic influenza A (H1N1) “swine flu” virus during the spring and summer of 2009. The scientists suggested that this finding could be due to the difference in the way the vaccine affects the immune system compared with natural infection.

Antibody responses to SARS-CoV-2 in patients with COVID-19

(29.04.2020)

We report acute antibody responses to SARS-CoV-2 in 285 patients with COVID-19. Within 19 days after symptom onset, 100% of patients tested positive for antiviral immunoglobulin-G (IgG).

All those infected develop antibodies says study in Nature

All the people who recover from COVID-19 develop antibodies, according to a study by Chongqing Medical University published in the Nature Medicine journal.
100% of the Infected Have Antibodies.
The study revealed that 100% of the patients analysed had IgG antibodies, the ones produced during the first infection and which give long-term protection.

“It’s much more sustainable.” Sweden has left its schools, gyms, cafes, bars and restaurants open throughout the spread of the #coronavirus pandemic. Anders Tegnell, the man behind this strategy, now says the country may be over the worst

‘Closing borders is ridiculous’: the epidemiologist behind Sweden’s controversial coronavirus strategy

What would you have done differently?

We underestimated the issues at care homes, and how the measures would be applied. We should have controlled this more thoroughly. By contrast, the health system, which is under unusual pressure, has nevertheless always been ahead of the curve.

Are you satisfied with the strategy?

Yes! We know that COVID-19 is extremely dangerous for very old people, which is of course bad. But looking at pandemics, there are much worse scenarios than this one. Most problems that we have right now are not because of the disease, but because of the measures that in some environments have not been applied properly: the deaths among older people is a huge problem and we are fighting hard.

Sweden’s chief epidemiologist says lockdowns may not save lives because 50% of their deaths are in care homes – and they’ll handle second wave better because they now have higher levels of immunity

A lockdown might not have saved lives in Sweden because half its coronavirus deaths are in care homes where visits are already banned, the country’s top disease expert said today.

State epidemiologist Anders Tegnell said it was ‚hard to understand‘ how a full-scale lockdown would have stopped the virus spreading into nursing homes.

While Sweden has avoided introducing a lockdown, it has banned visitors from care homes in one of its few restrictive measures, with schools, bars, shops and restaurants still open.

Study shows 13.9% of people tested in New York have coronavirus antibodies, Cuomo says

That suggests that 2.7 million people have been infected statewide.

The survey was taken from a sample size of about 3,000 people found outside their homes, shopping at essential businesses, such as grocery stores, which remain open.

Scientists say many more people than previously thought could have acquired coronavirus immunity after discovering 15% of people in city dubbed ‚German Wuhan‘ could be carrying antibodies

An immunity rate of 15 per cent is already enough to slow the spread of the virus significantly, they added.

However, they admitted that all governments need to collect more data as the world still doesn’t know enough about the virus.

Last week, research conducted by Prof Streeck showed that the home of one infected family did not have ‚any live virus on any surface‘, adding even more questions as to how the virus is spread from person to person.

Prof Streeck said the virus had not even been found on door knobs or animal fur.

Fauci: Recovered coronavirus patients will likely be immune if second wave hits in fall

While speaking with Journal of the American Medical Association editor Howard Bauchner Wednesday, Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases (NIAID), said that because the virus doesn’t seem to be mutating much, it’s unlikely people will test positive a second time.

“Generally we know with infections like this, that at least for a reasonable period of time, you’re going to have antibodies that are going to be protective,” Fauci said.
