Is there hope for a fight with Covid-19? The Oxford vaccine is said to be working

“The study found that the vaccine works effectively in cells. The immune system is then ready to recognize the disease and fight it without getting sick,” he writes. Daily Mail.

According to David Matthews, one of the experts who studied the effectiveness of the vaccine, the study is very important. Thanks to it, the researchers were able to confirm that the genetic information that is the basis of the vaccine is behaving correctly.

“Until now, technology has not been able to provide clear answers, but now we know that the vaccine is doing everything we expected. This is good news in our fight against the disease,” Matthews said.

At the same time, the study found that a huge amount of coronavirus S-protein is produced in the body with great precision. The vaccine uses only minimal genetic information from the virus. Information about the S-protein that connects to cells is added. The vaccine thus triggers a reaction in the human cell that makes copies of the protein, and anti-virus substances are formed after vaccination.

The vaccine is already in the third, and therefore noon, phase of clinical trials. Tens of thousands of people are involved. However, one of the volunteers died in Brazil. Read more in this article on TN.cz.

Ferrari Omologato, a Ferrari like no other

NEW – A name evoking the GTO, a rear hatch covered with louvers: Maranello’s latest bespoke creation offers a journey of nostalgia.

Ferrari

Even in the choice of appellation, the shadow of the famous Ferrari 250 GTO (O for Omologato) seems to have hovered over the design of the latest bespoke creation from the House of Maranello. From the 812 Superfast from which it borrows the platform and the V12, the Ferrari Omologato has kept only the windshield and headlamps. Everything else is new. This is what the informed European collector, at the origin of the order, wanted.

Ferrari

From the first sketches to the delivery of this unique berlinetta, two years have passed. The 250 GTO clearly inspired this unique berlinetta. The sloping and smooth front hood adopts two gills and a flattened oval grille that refer to those of the GTO of 1962. ‘a light car. The rear scrambles the cards. The louvers covering the large bezel suggest that the engine is installed at the rear. The two double lights of the 812 Superfast are replaced by a single equipment.

Ferrari

The interior treatment takes a trip back to the 1960s. Like those in racing cars and the 250 GTO, the leather and jeans fabric seats are electric blue, while the metal parts of the dashboard and the The arch housing the gearbox knobs mimic the crackle paintwork of sixties GTs.

The dispute over testing seniors for coronavirus is divided free of charge by the Central Bohemian Region. President Jerman defends him, the opposition criticizes him as dangerous populism

Pre-election debate: Central Bohemia, Part 1

“We also have to deal with crisis situations in social facilities, hospitals, schools, we have enough protective equipment, we have 9 collection points, so we are already in full swing,” said the current governor of the Central Bohemian Region at the beginning of the debate. Jaroslava Pokorná Jermanová from YES.

Leader CSSD Robin Povsik he complained about the lack of information about the planned measures, despite the fact that he was a member of the nationwide crisis staff. However, he is optimistic about the spread of coronavirus. “Our reproductive number is declining and it is a hope that the situation can improve and the health system will not collapse,” says Povšík. The measure is considered important for the protection of the health system in the republic.

The leader of the candidate counts on the restrictions SPD Radek Rozvoral. “I wouldn’t want leisure activities to be banned outside, I would understand inside,” Rozvoral thinks. If he were in charge of the region, he would like to take care of the most risky groups of citizens, such as seniors and health professionals, who should be equipped with respirators.

“The government failed, indebted our country by 500 billion crowns and wasted it. She has not been able to prepare hygienic stations to be able to trace all infected people, “he criticizes the action of the government parties Jiří Snížek (Pirates). The Central Bohemian Region is not as populated as Prague, so according to him it is necessary to take measures according to the density of settlements.

“I am a supporter of tougher measures, but I perceive the current one as being pulled out of a magic hat,” he criticizes. Zdeněk Štefek candidate for KSČM. According to him, people should know the measures in advance in order to be able to prepare for them. As part of a pandemic plan, it would propose several options for action, depending on the severity of the spread of the epidemic. It also criticizes, for example, the reduction in the number of hygiene workers more than 10 years ago.

“Once again, it turned out that the state could not be relied on, now as a mayor I do not receive any information compared to the spring, I get an Excel spreadsheet with the number of infected and healed in the district and that’s all,” he says. Petra Pecková for STAN, who is the mayor of Mnichovice. According to her, everyone is most frightened by the closure of schools, she would like to secure more sampling points in the Central Bohemian Region.

According to Martin Kupka from ODS rescuers in the region would need information on free capacities for patients with covid-19. “This will be key to dealing with a situation that is likely to require more ventilator sites,” Kupka said. Paramedics should know exactly where to take patients. According to him, people would need to be better informed.

“At the moment, I see it as the most crucial that tracing is collapsing for us, which is part of Smart Quarantine. If it is not possible to trace, then there will not be enough capacity in healthcare, “he says Jan Jakob (TOP 09 + Voice + Greens). At the moment, according to him, there are almost a thousand untraced cases and the employees of the region could help with this.

According to Antonín Fryč from Tricolor citizens need to regain confidence in public administration. He thinks that people no longer believe in its actions due to confused government decisions. “In the first wave, this country closed completely, the coronavirus did not spread and we spent 500 billion, which we will now find it difficult to put together,” criticizes Fryč. According to him, the second wave should be solved by experts and not politicians.

In July, measures in the Central Bohemian Region tightened again. For example, there was no pilgrimage in Křesetice. The measures were ordered by the Central Bohemian Hygiene Station due to an outbreak in the village of Církvice. Due to this, hospitals and homes for the elderly were closed to visitors in the district. Kutná Hora, which has long been an attraction for tourists, was noted by the coronavirus.

Outbreaks have occurred in the region mainly in schools, sports clubs and after cultural events. According to hygienists, many people spread the infection to the region from Prague. In the summer, restaurants or bars were limited to midnight closing hours. After Prague, the Central Bohemian Region is now the most affected region.

Tests for covid-19 free for seniors

The current President Pokorná Jermanová (YES) would go to the Benešov hospital if necessary. She has tried the procedure from the spring when she was quarantined. However, given the current capacity of testing in the region and the occupancy of reservation systems, a person with a suspected coronavirus infection can learn the test result in up to 9 days. According to her, the governor would go to the queue for the hospital if she did not have a reservation.

“By the time the region and the governor wrote on the website that sampling points were available until 7 pm and people could go for testing after work, the Příbram hospital was already collapsing, not taking out self-payers and had an ordering system long in advance “Responds Petra Pecková from STAN. She also criticized the fact that in regional hospitals, seniors should be able to test with a free rapid test.

According to President Jermanová from ANO, the region wanted to offer all seniors the same opportunity, because they are tested in social facilities in this way. “I know a case where a student was sent for a test, waited in the hospital for several hours and had a result the next day,” defends the region’s member coalition member Robin Povšík from the CSSD. “Chasing seniors without symptoms to stand in line is pure populism,” thinks Martin Kupka of the ODS. According to him, it will only be a burden for the healthcare system, he only wants to send people with symptoms for testing and for tracing.

“I am convinced that seniors should have special care, they will always receive it under our guidance, and these are not unnecessary activities,” stands President Jermanová.

Jiří Snížek from Pirátů criticizes the region’s approach from the point of view of information. Robin Povšík from the CSSD is accused of relying on information from the crisis staff. There are over a thousand municipalities in the region and according to him, everyone should be better informed.

“We fail to inform the infected that they are infected, which is a huge failure,” says Snížek. “It is completely absurd to overload the system with testing, which is not necessary,” continues Jan Jakob (TOP 09, Voice, Greens). He does not want to stress seniors by testing, but rather to protect them with quality aids.

“The fact that someone has free tests to go there is completely useless,” thinks Antonín Fryč from Tricolor. He also does not want people who take the test to meet because they have symptoms and those who need the test, for example, preventively to travel abroad. “The number of test capacities needs to be increased,” he says.

According to Radek Rozvoral from the SPD, the Central Bohemian Region has worse medical care in places where there are no regional hospitals. “I was surprised that Central Bohemian hospitals have, for example, three times less staff in the ICU and ARO departments, we should do something to increase the numbers,” comments Rozvoral.

Robin Povšík from the CSSD, who participates in the current government in the region, highlights the care of the elderly in residential facilities, where the number of cases of illness is currently increasing. In this, Martin Kupka from the ODS warns against the lack of staff to take care of the elderly.

According to Zdeněk Štefek from the KSČM, there is already an acute shortage of staff in health care and social services in the region, as the number of infected people is growing. “They are already working beyond the legal conditions, I think there is room for volunteers and the involvement of the Czech Red Cross,” says Štefek.

Instead of seniors, Jiří Snížek from Pirates would like to test the staff of their homes. According to him, it would be a better use of money. According to President Pokorná Jermanová from ANO, this is now happening, and the region has also prepared contingency plans in the event of an infection in a social facility.

Jan Jakob (TOP 09, Hlas, Zelení) also criticizes the ambiguity of the traffic light, which is supposed to show the severity of the infection in individual districts. “It’s as if green in Příbram at the crossroads meant that we could go and not in Benešov anymore. The traffic light doesn’t work very well anymore, “he thinks. He criticizes the government for wasting time, resources and populism. “We will overload the paramedics now, and when we need them the most, they won’t, and the whole thing will collapse like a house of cards,” warns Jakob.

“We should always be one step ahead, saying that when it happens, we will solve it, I think it is very late,” says Antonín Fryč from Tricolor. He would like the region to have a plan, for example, for the construction of mobile hospitals and the protection of health professionals. “If we become infected, we will not need hospitals at all, because there will be no one to serve there,” he concludes.

According to Robin Povšík from the CSSD, the Republican Central Crisis Staff is now dealing with similar issues.
“We must all do our utmost to have as few hospitalized as possible, as few dead as possible, not to make it a political campaign like some politicians and, most importantly, not to advertise the virus,” concludes Robert Rozvoral of the SPD.

The debaters nominated for the debate based on the results of a survey conducted for Czech Television by Kantar CZ and Data Collect, focusing on voting potential. It shows what percentage of votes a political party, movement or coalition could currently gain in the election hypothetically if all people who are really considering this election and do not exclude their participation in the election support it.

Experts from the International Center for Clinical Research at the University Hospital at St. Anny in Brno is discussing the possibility of participating in the testing of a new vaccine against Covid. Hundreds of volunteers would be involved in the study.

The center is currently negotiating with the vaccine manufacturer. “In Brno, we would conduct the third phase of a clinical study in which the vaccine is tested on a large number of volunteers and a large number of side effects are not expected to occur,” said Pavel Iványi, director of the research center.

Department of Clinical Studies of the Hospital at St. Anny works on dozens of studies at all stages of her research. “We would like to take this opportunity. We take this as a certain confirmation that our hospital is medically at a very high level, “commented Vlastimil Vajdák, the hospital’s director.

The manufacturer will decide in the coming weeks whether the hospital will be involved in testing the vaccine.

Experts around the world are working on the Covid vaccine. The World Health Organization currently registers 169 possible vaccines, 26 of which are already in the final stages of testing.

How reliable is the corona test? – Science

Brazilian researchers examined the reliability of the various corona tests. This shows that there is less certainty with a weak positive result or a negative result.

The World Health Organization recommends having as many corona tests as possible. Based on the test results, we measure our progress in the fight against the virus and determine measures. But how reliable is such a corona test?

How reliable a test is is expressed in two terms: specificity and sensitivity.

Specificity

  • The specificity is the 100 chance that a test will produce a negative result in individuals who are not infected with the coronavirus. So it is the chance in 100 to find non-sick people.
  • With a specificity of 100%, everyone who does not have the disease scores negatively: perfect.
  • With a specificity of 0%, no one scores negative who does not have the disease: a disaster. This means that anyone who is not infected with the virus still scores positively, as if they were infected with it. Of course you cannot do anything with such a test.

Sensitivity

  • The sensitivity is the chance in 100 that a test will yield a positive result in people infected with the corona virus. So it is the chance in 100 of detecting sick (or contagious) people.
  • With a sensitivity of 100%, everyone who has the disease scores positively: ideal.
  • With a sensitivity of 0%, no one scores positively with the disease. This means that anyone infected with the virus will still score negative, as if they were not infected with it. That is also a worthless test.

The perfect test scores 100% on specificity and 100% on sensitivity, but such an ideal is difficult to achieve.

What about the corona tests?

Brazilian researchers examined the reliability of the various corona tests (1).

  • For specificity, the various tests scored above 95%: in other words, a maximum of 5% of the tests gives a positive result, while the persons are not infected with the corona virus. We call these false positive results.
  • For sensitivity, the tests generally scored much lower, even below 90%. That means that at least 10% of the people test negative while they are still infected with the corona virus. We call these false negative results.

In false positive tests, we place people in unnecessary quarantine. People who take a false negative test can then unknowingly infect other people.

The researchers conclude that there is an urgent need for simple and inexpensive tests with few false negative results.

How should we interpret this news?

Weak positive results

In practice, two situations can occur: you test positive or your test negative for the corona virus. With a positive test, there is a good chance that you are infected with the virus. With a negative test there is a chance that you are infected, but that the test ‘was wrong’.

The story gets a little more difficult when you know that even small amounts of coronavirus genetic material can already cause a positive test result. We call this a weak positive result. It can occur when:

  • you just got infected;
  • the sample was not collected properly;
  • the contamination took place in the past.

The doctor decides

With weak-positive results, a doctor therefore also takes into account symptoms such as cough, sore throat, fatigue, loss of taste and smell. He does this in order to be able to decide whether someone with a weak positive result should be quarantined or not. Conversely, with a negative test, a doctor will also check whether you have any symptoms, to rule out false negative results as much as possible.

A doctor can always ‘overrule’ a negative test. That is, if a doctor strongly suspects that someone is infected, he decides to consider the person in question as covid-19 positive, even if his test result is negative. A doctor’s judgment remains important, so we should not focus solely on a test result alone.

Conclusion

The result of the corona test does not in itself give any certainty, but only increases or decreases the likelihood that you are infected or not. You have less certainty with a weak positive result or a negative result. Then you have to take into account not only the test result, but also any symptoms.
