My experience with Russia's Sputnik V COVID-19 vaccine

DW's Sergey Satanovskiy was one of many people who took part in a testing program for the Russian COVID-19 vaccine, Sputnik V. After receiving two shots, he visited his grandmother — and came in contact with coronavirus.



Russia's Sputnik V vaccine is already being rolled out

People in Russia are currently being inoculated against COVID-19, even though stage-three trials of the country's Sputnik V vaccine aren't due to be completed until May.

DW's Sergey Satanovskiy was among the volunteers who agreed to testthe new vaccineand report back in December what it was like to get his first shot and three weeks later his second, the Sputnik V booster. He was then tested for antibodies following the two inoculations. This is his story:

I was actually feeling fine before my antibody test. I had been given the two vaccination doses and hadn't experienced side effects, so on New Year's Eve I decided to visit my 74-year-old grandmother, who happens lives just outside St. Petersburg. I didn't have any symptoms at the time but took a COVID PCR test anyway. The result was negative.

My grandmother moved out of the city and into the country a year ago and has stayed away from St. Petersburg since the outbreak of the virus. She heats her house by turning on her oven and travels once a week to the next town, with 17,000 inhabitants, to do her shopping. But even being 300 kilometers (190 miles) away from the big city didn't mean that she escaped the coronavirus.

She developed a cough on New Year's Day, which continued into the next day. We thought at first that she had caught a cold, because it was so cold outside. We didn't think that she had the coronavirus. On January 3, I went back to St. Petersburg.

That same night my temperature climbed to 37.4 degrees Celsius and I developed a sore throat. My grandmother told me she had similar symptoms.

My symptoms were gone two days later. My grandmother, however, had a fever for three days running and felt pretty weak. She called a doctor and took a COVID PCR test. The results were positive. Although she didn't have to go to the hospital, she did get pretty sick. She had a fever for three weeks, her blood pressure increased and she felt weak and lousy for quite a while.

I, too, took a COVID PCR test and the results were negative.

'Lots of antibodies'


Wadim Lynjew, who heads up the lab at the Shostakovich Hospital where I got my two shots, said that the reaction of vaccinated individuals who come in contact with COVID-19 depends on the viral load they're exposed to. If someone who has been vaccinated comes in contact with someone who is only mildly sick, the vaccinated person often doesn't feel anything. But if the vaccinated person is confronted by a high viral load, they could get sick but have a milder case.

That's exactly what happened to me. I was exposed to a lot of the virus when I visited my grandmother but didn't really get sick because of the antibodies in my system. My grandmother had it much worse but is now feeling better, and I'm happy to report that her most recent COVID test was negative.

I was tested for antibodies a few days after returning from St. Petersburg and had the results the next day, which according to Dmitri Denisov, the medical director of the Helix Lab, were good results, especially when compared with others who were vaccinated or had COVID-19.


Sputnik V was already being administered in Russia in mid-December


What seems to be certain is that my antibodies are due to my Sputnik V vaccine. If I had been ill with the virus, I wouldn't have been able to build up so many antibodies, so quickly in the short time leading up to the antibody test.
Does Sputnik V prevent COVID?

According to Denisov, everyone has a different immune response after getting the vaccine. "It depends on numerous factors," he said. "Previous illnesses, recent infections and the kinds of diets people have, not to mention the individual way in which people respond generally."

No one can say for sure whether having the same level of antibodies as I had could offer failproof protection from getting COVID-19. According to Denisov, the jury is still out on the matter, since worldwide vaccinations are just beginning and clinical trials are winding down.

Babyn Yar: The Holocaust's biggest massacre

Between 1941 and 1943, Nazi forces shot almost 34,000 Jews in the ravine at Babyn Yar on what was then the edge of the Ukrainian capital, Kyiv. But where exactly did the victims lose their lives? The precise location of the Holocaust's biggest massacre was unclear for decades.







Ultrasound Blasts 'Jumpstarted' The Brains of 2 People in Coma-Like State

DAVID NIELD
31 JANUARY 2021

Scientists have reported finding some success in using low intensity, focused ultrasound to 'jumpstart' parts of the brains of people in coma-like conditions, reawakening certain functions in patients who had previously been in a "minimally conscious state" (MCS).

The method uses ultrasound stimulation to excite the neurons in the thalamus, a processing hub for the whole brain, and a region that's known to be weaker after a coma. Two 10-minute treatment sessions were given to three MCS patients, with a week between each session.

While one patient showed no response, researchers observed significant improvements in the other two patients. The research builds on similar findings from 2016, involving one patient who was recovering from surgery and a medically induced coma. In the new study, the coma-like states had lasted much longer.

A person in a minimally conscious state may show clear but subtle or inconsistent signs of consciousnesses. These signs, like blinking on command or wakefulness, are generally sustained enough that they aren't seen as reflexive behaviours, and they help to differentiate MCS from comas or vegetative states.

"I consider this new result much more significant because these chronic patients were much less likely to recover spontaneously than the acute patient we treated in 2016 – and any recovery typically occurs slowly over several months and more typically years, not over days and weeks, as we show," says neuroscientist Martin Monti, from the University of California, Los Angeles (UCLA).


"It's very unlikely that our findings are simply due to spontaneous recovery."

One of the patients to respond to the treatment was a 56-year-old man, who had been in a minimally conscious state for more than 14 months, unable to communicate at all. After treatment, he could not only look towards the photographs of relatives when their names were mentioned, he could also drop or grasp a ball on demand. When asked simple questions about his identity, he was able to shake his head 'yes' or 'no'.

The other patient to show signs of progress, a 50-year-old woman, had been in an even deeper MCS for more than two-and-a-half years. After the ultrasound sessions, she was able to understand speech and recognise basic objects, including a pencil and a comb.

Researchers say the technique is safe as it only uses a small amount of energy, and there were no changes to the blood pressure, heart rates, or blood oxygen levels of the patients.

"This is what we hoped for, but it is stunning to see it with your own eyes," says Monti. "Seeing two of our three patients who had been in a chronic condition improve very significantly within days of the treatment is an extremely promising result."

It's important to emphasise that the research is still in an early and experimental phase. While the 50-year-old woman showed increased signs of awareness months afterwards, the differences from the MCS starting point weren't that significant. And after a few months without treatment, the 56-year-old man had returned to something close to his original coma-like state.

Add in the one patient that didn't respond at all to the treatment, and the researchers remain cautious about how successful ultrasound can be, and how quickly it can be rolled out. Nevertheless, these results are very encouraging – there are definite signs that this kind of treatment could help some patients some of the time.

The treatment can be applied in a device about the size of a saucer, and the researchers are hoping that it can eventually be used in the home on patients who are in long-term minimally conscious or vegetative states.

"Importantly, these behaviours are diagnostic markers of emergence from a disorder of consciousness," says Monti. "For these patients, the smallest step can be very meaningful – for them and their families. To them it means the world."

The research has been published in Brain Stimulation.

New COVID-19 test uses a smartphone microscope to quickly analyze saliva samples

Researchers at the University of Arizona are developing a COVID-19 testing method that uses a smartphone microscope to analyze saliva samples and deliver results in about 10 minutes.

The UArizona research team, led by biomedical engineering professor Jeong-Yeol Yoon, aims to combine the speed of existing nasal swab antigen tests with the high accuracy of nasal swab PCR, or polymerase chain reaction, tests. The researchers are adapting an inexpensive method that they originally created to detect norovirus - the microbe famous for spreading on cruise ships - using a smartphone microscope.

They plan to use the method in conjunction with a saline swish-gargle test developed by Michael Worobey, head of the UArizona Department of Ecology and Evolutionary Biology and associate director of the University of Arizona BIO5 Institute.

The team's latest research using water samples - done in collaboration with Kelly A. Reynolds, chair of the Department of Community, Environment and Policy in the UArizona Mel and Enid Zuckerman College of Public Health - is published today in Nature Protocols.

We've outlined it so that other scientists can basically repeat what we did and create a norovirus-detecting device. Our goal is that if you want to adapt it for something else, like we've adapted it for COVID-19, that you have all the ingredients you need to basically make your own device."

Lane Breshears, Biomedical Engineering Doctoral Student

Yoon - a BIO5 Institute member who is also a professor of biosystems engineering, animal and comparative biomedical sciences, and chemistry and biochemistry - is working with a large group of undergraduate and graduate students to develop the smartphone-based COVID-19 detection method.

"I have a couple of friends who had COVID-19 that were super frustrated, because their PCR results were taking six or seven days or they were getting false negatives from rapid antigen tests. But when they got the final PCR tests, they found out they had been sick, like they'd suspected," said Katie Sosnowski, a biomedical engineering doctoral student who works in Yoon's lab. "It's really cool to be working on a detection platform that can get fast results that are also accurate."

Cheaper, simpler detection

Traditional methods for detection of norovirus or other pathogens are often expensive, involve a large suite of laboratory equipment or require scientific expertise. The smartphone-based norovirus test developed at UArizona consists of a smartphone, a simple microscope and a piece of microfluidic paper - a wax-coated paper that guides the liquid sample to flow through specific channels. It is smaller and cheaper than other tests, with the components costing about $45.

The basis of the technology, described in a 2019 paper published in the journal ACS Omega, is relatively simple. Users introduce antibodies with fluorescent beads to a potentially contaminated water sample. If enough particles of the pathogen are present in the sample, several antibodies attach to each pathogen particle. Under a microscope, the pathogen particles show up as little clumps of fluorescent beads, which the user can then count. The process - adding beads to the sample, soaking a piece of paper in the sample, then taking a smartphone photograph of it under a microscope and counting the beads - takes about 10 to 15 minutes. It's so simple that Yoon says a nonscientist could learn how to do it by watching a brief video.

The version of the technology described in the Nature Protocols paper makes further improvements, such as creating a 3D-printed housing for the microscope attachment and microfluidic paper chip. The paper also introduces a method called adaptive thresholding. Previously, researchers set a fixed value for what quantity of pathogen constituted a danger, which limited precision levels. The new version uses artificial intelligence to set the danger threshold and account for environmental differences, such as the type of smartphone and the quality of the paper.

On-campus impact

The researchers plan to partner with testing facilities at the University of Arizona to fine-tune their method as they adapt it for COVID-19 detection. Pending approval of the university's institutional review board, students who are already being tested on campus through other methods will have the option to provide written consent for their sample to be run through the smartphone-based testing device as well. Ultimately, the researchers envision distributing the device to campus hubs so that the average person - such as a resident assistant in a dorm - could test saliva samples from groups of people.

"Adapting a method designed to detect the norovirus - another highly contagious pathogen - is an outstanding example of our researchers pivoting in the face of the pandemic," said University of Arizona President Robert C. Robbins. "This promising technology could allow us to provide fast, accurate, affordable tests to the campus community frequently and easily. We hope to make it a regular part of our 'Test, Trace, Treat' strategy, and that it will have a broader impact in mitigating the spread of the disease."

Yoon and his team are also working on another idea, based on a 2018 paper they published in Chemistry--A European Journal, which is even simpler but leaves slightly more room for error. It involves the same technology, but instead of a smartphone microscope and specially designed enclosure, users would only need to download a smartphone app and use a microfluidic chip stamped with a QR code.

"Unlike the fluorescent microscope technique, where you get the chip into just the right position, you just take a snapshot of the chip," said biomedical engineering master's student Pat Akarapipad. "No matter the angle or distance the photo is taken from, the smartphone app can use AI and the QR code to account for variances and run calculations accordingly."

The method requires no training, so, if perfected, it could potentially allow students to pick up microfluidic chips from a campus location and test their own samples. The team is also working with other members of the university's COVID-19 testing group, including Deepta Bhattacharya, an associate professor in the Department of Immunobiology.

FAA is reportedly investigating SpaceX over its Starship tests

SpaceX’s high-altitude test of its Starship prototype SN8 in December 2020 ended in an explosive fireball, though company CEO Elon Musk seemed happy with the data collected during the test. But the Federal Aviation Administration (FAA) which oversees regulations for rocket launches is concerned about the explosion and other issues, according to reports which say SpaceX is now the subject of an FAA investigation.

As reported by The Verge, the explosion in December is not the FAA’s only concern. The agency is reportedly also concerned about breaches of SpaceX’s test license, and has opened an investigation into the company. The exact details of what SpaceX supposedly did in violation of its license has not yet been made public.

“The FAA will continue to work with SpaceX to evaluate additional information provided by the company as part of its application to modify its launch license,” FAA spokesman Steve Kulm said, as reported by The Verge. “While we recognize the importance of moving quickly to foster growth and innovation in commercial space, the FAA will not compromise its responsibility to protect public safety. We will approve the modification only after we are satisfied that SpaceX has taken the necessary steps to comply with regulatory requirements.”

The issues with the FAA put the brakes on plans for another high-altitude test of the newer SN9 prototype, which had been expected to go ahead this week. The test had to be postponed after the FAA lifted the temporary flight restrictions in the airspace around the test site.

In this context, CEO Elon Musk was critical of the FAA on Twitter, saying its space division has “a fundamentally broken regulatory structure” and that its rules were not reflective of the modern situation of multiple expendable launches being performed regularly.

Now, SpaceX has two prototypes ready to test — both the SN9 and the SN10. Both prototypes have been seen side by side on the SpaceX pad at Boca Chica. Space.com speculates that the next test flight could go ahead next week, from Monday, February 1, as long as the approvals from the FAA are granted in time.

UK to apply to join free trade pact with nations on other side of world

Liz Truss to seek to join 11-nation trans-Pacific partnership, whose nearest member is 3,000 miles away

The British government is to formally apply to join a mammoth free-trade pact that includes Australia, Canada, Japan and New Zealand now that it has left the EU.

Liz Truss, the international trade secretary, will ask to join the Comprehensive and Progressive Trans-Pacific Partnership (CPTPP) when she speaks to ministers in Japan and New Zealand on Monday.


Negotiations are expected to start later this year, Truss’s department said, in announcing the move on the anniversary of the UK’s formal departure from the EU.

Joining the CPTPP will cut tariffs in trading with its members. UK trade with the group last year was worth £111bn, according to the Department for International Trade.

The pact’s 11 members are:


Australia.


Brunei.


Canada.


Chile.


Japan.


Malaysia.


Mexico.


New Zealand.


Peru.


Singapore.


Vietnam.

Boris Johnson said: “One year after our departure from the EU, we are forging new partnerships that will bring enormous economic benefits for the people of Britain.

“Applying to be the first new country to join the CPTPP demonstrates our ambition to do business on the best terms with our friends and partners all over the world and be an enthusiastic champion of global free trade.”

British businesses reacted warmly to the plans, with the Federation of Small Businesses (FSB) saying the move would help firms “thrive and succeed more than ever”.

But the shadow international trade secretary, Emily Thornberry, said Labour will closely scrutinise any pact and called on the government to consult the public.

“Like any other trade agreement, the advantages of joining the CPTPP will have to be assessed once we see the terms on offer,” she said.

“At present, Liz Truss cannot even guarantee whether we would have the right to veto China’s proposed accession if we join the bloc first.

“More generally, people will rightly ask why we have been through five years of debate in Britain over leaving a trade bloc with our closest neighbours only to rush into joining another one on the other side of the world without any meaningful public consultation at all.”

Truss said joining the pact would “create enormous opportunities for UK businesses that simply weren’t there as part of the EU”.

The Confederation of British Industry president, Lord Bilimoria, said: “Membership of the bloc has the potential to deliver new opportunities for UK business across different sectors.”

Sue Davies – head of consumer protection and food policy at Which? – said ministers must ensure joining CPTPP “will bring clear consumer benefits” and will not dilute standards.

Two new Covid vaccines have less efficacy against South African strain

Early trial data shows Novavax and Johnson & Johnson vaccines have much less efficacy against new variant

Early data from two new coronavirus vaccine trials has indicated that they have less efficacy at protecting from the South African variant of coronavirus.

Clinical trial data showed that the vaccines from Novavax and Johnson & Johnson had significantly less efficacy at preventing coronavirus in trial participants in South Africa, where the new variant is widespread, compared with countries where the variant is less common.

Novavax reported that results from mid-stage trials on Thursday showed its vaccine had 50% efficacy overall in preventing Covid-19 among people in South Africa. In late-stage results from the UK, the vaccine had up to 89.3% efficacy

On Friday, Johnson & Johnson said a single shot of its vaccine had 66% efficacy, judging by a large-scale trial which spanned three continents. In the US, which recorded its first cases of the South African variant this week, the vaccine’s efficacy reached 72%, but it was just 57% in South Africa, where the new variants constituted 95% of the coronavirus cases in the trial.

The trial results also raise questions over the efficacy of the vaccines currently in circulation, such as the Pfizer/BioNTech which has been distributed in the UK. While the vaccines showed high efficacy, the trials were largely undertaken before the South African variant had spread widely.

Dr Dan Barouch, a researcher at Harvard University medical school’s Beth Israel Deaconess medical centre in Boston who helped develop the Johnson & Johnson vaccine, said the new variant meant this was a “different pandemic now”.

Speaking at the World Economic Forum, Pfizer’s chief executive, Albert Bourla, said there was “a high possibility” that the new strains could eventually mean the firm’s vaccine was redundant.

“This is not the case yet … but I think it’s a very high likelihood that one day that will happen,” Bourla said. Pfizer is considering whether its vaccine needs to be altered to protect against the South African variant.

Despite the new variant, experts said that existing vaccines were still valuable in the fight against coronavirus, and Johnson & Johnson’s vaccine was 89% effective at preventing severe disease in South Africa.

“The end game is to stop death, to stop hospitals from going into crisis and all of these vaccines, even including against the South African variant, seem to do that substantially,” said Dr Amesh Adalja, an infectious disease expert at the Johns Hopkins Center for Health Security.

The number of people suffering from flu has plunged to levels not seen in more than 130 years


One expert has said that flu had been 'almost wiped out'

While coronavirus infection rates remain high, flu has been "almost wiped out" with cases plunging by 95% to levels not seen in more than 130 years.

The peak of the season is usually the second week of January, but official data for that time shows that the number of flu-like cases reported to doctors was 1.1 per 100,000 people, compared to a five-year average rate of 27.

In Wales, the latest figures show that that figure in Wales for the week ending January 24 was 0.8 per 100,000.

Simon de Lusignan, professor of primary care at the University of Oxford and director of the Royal College of GPs research and surveillance centre, which focuses on flu told The Sunday Times that flu had “almost completely wiped out."

He added: "I cannot think of a year this has happened."


John McCauley, director of the World Health Organisation's collaborating centre for reference and research on influenza and one of the world's leading flu experts, told the paper: "The last time we had evidence of such low rates was when we were still just counting influenza deaths, and that was in 1888, before the 1889- 90 flu pandemic."


Flu is virtually non-existent in Wales so far this winter

It is thought the health measures taken to combat Covid-19 like social distancing and hand washing are likely to be the main reason for the dramatic fall in cases.

A similar trend was seen in the southern hemisphere last year with very few cases of seasonal flu in Australia, Chile and South Africa there between April and July 2020.


A Public Health Wales spokesman has said social distancing, better hand hygiene and masks to contain the spread of Covid-19 were having an impact on flu rates.

Former QAnon Follower To Anderson Cooper: ‘I Apologize For Thinking That You Ate Babies’

Damir Mujezinovic INQ UISITER

CNN anchor Anderson Cooper recently interviewed Jitarth Jadeja, a former QAnon supporter, who earnestly believed in some of the most absurd conspiracy theories peddled by the mysterious Q.

As HuffPost reported, according to a clip of the interview that was released on Saturday, Jadeja apologized to Cooper for once thinking he “ate babies.”

“Did you, at the time, believe that Democrats, high-level Democrats and celebrities were worshipping Satan, drinking the blood of children?” Cooper asked.

“Anderson, I thought you did that. And I would like to apologize for that right now. So, I apologize for thinking that you ate babies.”

Cooper was taken aback by Jadeja’s apology and asked him to confirm that he really thought prominent political and media figures ate small children.

“Yes, I did,” Jadeja replied, noting that many QAnon followers believe that, though some actually think Cooper is a robot.

Jadeja explained that he once believed QAnon was part of “military intelligence” and stressed that he also thought that aliens were involved in the QAnon movement and supporting the mysterious individual.

The man said that he believed that “the people behind him were actually a group of fifth dimensional intra-dimensional extra terrestrial bipedal bird aliens called blue alien.”

“I was so far down in this conspiracy black hole that I was essentially picking and choosing whatever narrative that I wanted to believe in,” Jadeja added.

Jadeja, who lives in Sydney, Australia, abandoned the QAnon movement in 2019. He claims to have been deradicalized by YouTube videos that debunked the very premise of the bizarre conspiracy theory.

Dozens of different theories fall under the umbrella of QAnon, but most of the claims are centered around the suggestion that former President Donald Trump and his allies are secretly fighting a global cabal of Satan-worshiping child traffickers.
