COVID-19 vs Antibody: Antibody Points Can Be Used to Make Vaccines, Experts Say | Instant News


Medical experts and the scientist is working hard to develop the vaccine needed to stop the new coronavirus pandemic which is now gripping the world. According to a report in Fox News, scientists are currently trying to understand how they can use antibodies to develop vaccines that can effectively stop the corona virus that has killed more than 24,737 people in the United States and affected more than 2 million people worldwide.

Scientist Linqi Zhang showed a tube with a solution containing COVID-19 antibodies in the lab where he worked on a new coronavirus (COVID-19) antibody research for possible use in drugs at the Tsinghua University Public Health Research Center in Beijing, China, March 30, 2020.

Based on Fox News, researchers from the Scripps Institute in California conducted a study that looked at how antibody points could be used as a vaccine for infectious viruses. The study was recently published by the United States National Library of Medicine, National Institutes of Health on April 3.

Antibody points can be the answer of COVID-19 vaccine experts

According to NIH Director’s blog, the scientists who carried out the study made a map that highlights other characteristics of human antibodies that can be used to make vaccines for the corona virus. They use high-resolution X-ray crystallography to develop images, capture the atomic structure of antibodies.

The developed map image shows the structure of human antibodies: yellow light chains and orange heavy chains. The chain mentioned is the blood protein produced by the human immune system to protect the physical body from attacks by foreign elements and viruses.

The group of scientists discovered a certain antibody called “CR3022,” which could be a key surface protein from a novel coronavirus.

This study clarifies that CR3022 antibodies are not produced by the body of a person recovering from a coronavirus infection. The scientists reiterated that the antibodies were obtained by a person who survived a severe respiratory syndrome (SARS) nearly two decades ago. SARS, which disappeared in 2004, is a close relative of the SARS-CoV-2 virus that causes COVID-19.

That studies of previous researchers showed that CR3022 cross-reacted with the corona virus, even though its structure was not sufficiently bound to neutralize the corona virus and stop it from infecting other cells.

That study highlights antibodies called ACE2 that are bound to spike proteins attached to novel coronaviruses and SARS, which allow them to attach to key receptor proteins produced by human cells that can be found on the cell surface. This activity in the human body provides the first step for coronaviruses to enter human cells and successfully infect them.

However, CR3022 binds to spike proteins from different corona viruses compared to ACE2. Research shows that CR3022 attaches to a novel coronavirus that is usually hidden unless the virus changes its shape to pollute cells.

The results showed that a successful vaccine could be developed with the help of CR3022 to target the same place of the corona virus, stopping it from infecting human cells. That the scientist are still working on this study by collecting blood samples from patients who have recovered from COVID-19.

COVID-19 Superspreaders: Some People Are More Contagious than Others, scientists say | Instant News


Novel coronavirus continues to spread throughout the world, infecting large numbers of people every day. And as the pandemic continues, no one can be sure whether the person you are traversing carries the SARS-CoV-2 virus or not. According to a report in Chicago Tribune, scientists found that there are people who are more infectious than others.

These people are called “Superspreaders“- those who infect a disproportionate number of individuals. The reason for this phenomenon is not yet clear. Scientists are clarifying that those who carry the virus can actually encourage” superspreading epidemics “events and worsen the situation. Therefore it is important for researchers to determine how this happens to people.

Some People Are More Contagious According to Scientists, Are You Still Safe?

However, the scientist also emphasized that it was also important to identify people who were infected but could not spread the disease.

According to an epidemiologist at the University of Michigan, Jon Zelner, identifying people who are more infectious than others and those who are less contagious can make a big difference in reducing the spread rate at the location where the outbreak occurred. Contact tracking is an important tool in dealing with supersebar. However, if it is done on someone who does not appear to transmit the virus to others, then that can be a waste of time and resources.

“The hard part is we don’tknow who those people are, “Zelner said.

Some people are more infectious than others, according to scientists; are you still safe

Martina Morris, an emeritus professor of statistics and sociology at the University of Washington, told the Chicago Tribune report that two factors influence supersebar:

Some People Are More Contagious According to Scientists; Are You Still Safe?

“There must be a relationship between people to transmit the infection,” he said. He also explained that the link was important but not enough.

According to Morris, the second factor is how contagious someone is. “We almost never have independent data about those two things.”

Professor reaffirmed that exposing someone to a public attack can easily misinterpret some infections in that person – even if viral contamination has nothing to do with the individual’s infection. He points out that if someone is the first person to be infected in a crowded room, and the spread is fast, he can easily be accused of being a supersebar.

However there is example where several individuals have caused a large outbreak. Thomas Frieden, former director of the Centers for Disease Control and Prevention and chief executive at Resolve to Save Lives, clarified that there was no evidence that individuals with silent infections were included in so-called superspreaders.

China Uses Zoom To Spy on Americans, US Officials Say | Instant News


According to US officials, Chinese spies have targeted America during the ongoing pandemic using the popular teleconferencing application, Zoom. Because locking is caused by coronavirus has forced millions of employees to work from home, the video conferences have become the norm where private company information sharing teams.

China Uses US Zoom To Spy US Officials Said

However, this application also provides a playground not only for cyber criminals, but also for spies. Zoom was previously accused of having weak security measures over allegations that it was sharing user information with third parties, and that incidents of “zoom bombing” – where trolls and strangers entered private video conferences – were commonplace. US Intelligence Officials have observed that Russia, Iran, North Korea and China are trying to spy on Americans using Zoom and other video chat platforms during video conferences.

Chinese spies target Americans during video conferencing: Why isn’t it safe to use Zoom?

According to a Time reported, three US counter-intelligence agents observed that foreign spies were observing Americans through popular applications. Intelligence officials stated in reports that among foreign cyberspies, China was the fastest and most aggressive.

“More than anyone, Chinese are interested in what American companies are doing,” said one of three US officials.

Intelligence officials and internet security researchers are increasingly worried because Chinese, Russian and other foreign countries are focusing on the virtual tools used by millions of Americans because they are forced to work from home. One of them, of course, Zoom.

According to reports from Citizen Lab On April 3, a research organization at the University of Toronto discovered several security issues with teleconferencing applications. One of them makes users very vulnerable to China. Application encryption keys through Chinese servers are weak and responsive to pressure from Chinese authorities because ownership depends on Chinese labor.

Zoom responded to resolve the issue with several public statements. After US intelligence officials claimed that the application platform had end-to-end encryption for all conferences, Zoom clarified that encryption was absent from some online messaging tools.

“Although we never intended to deceive our customers, we realize that there is a difference between the generally accepted definition of end-to-end encryption and how we use it,” Zoom Chief Product Officer Oded Gal told his the blog on April 1.

However, an investigation was carried out by Citizen Lab found another problem in Zoom security. They found that the key for conference encryption and decryption was sent to one of the Zoom participants located in Beijing. The investigation could find five servers in China and 68 in the United States that have Zoom server software, the same as those owned by Beijing servers.

US intelligence officials, who requested anonymity, clarifying that no evidence was found which shows that Zoom cooperates with China.
