COVID-19. British scientists dedramatize new variants of effects – observer
British scientists this Saturday downplayed alarm over the Omicron variant of the coronavirus that causes Covid-19, admitting that, despite many genetic mutations, vaccines are likely to remain effective in preventing serious illness.
Immunologist Andrew Pollard, director of the Oxford University Vaccine Research Group that developed the covid-19 vaccine for the AstraZeneca lab, told the BBC that many variant mutations are present in other SARS-CoV-2 strains for which vaccines have proven to be effective. …
“Mutations [da Ómicron] there are other options, and vaccines have been able to prevent serious illness from [variantes] Alpha, Beta, Gamma and Delta, ”said a researcher from the UK, where the new strain has already been discovered.
According to microbiologist Calum Semple, it is “likely that the immunity” afforded by the Covid-19 vaccines “still protects” against serious illness that the new variant could cause.
Semple considered it advisable that several countries suspended flights to southern Africa in order to “buy time” to intensify vaccinations and assess the true health impact of the new strain.
It is still not known for certain whether micron is more transmissible or dangerous, as it causes more serious illness, death and eludes the protection provided by Covid-19 vaccines.
Microbiologist João Paulo Gomes said Friday in a statement to Lusa that the new SARS-CoV-2 strain, originally discovered in South Africa, is “troubling” given the large number of genetic mutations it presents, in particular in the viral spike protein. which allows it to enter human cells.
However, there is no cause for concern for National Institutes of Health researcher Dr. Ricardo Jorge, as having multiple matching mutations does not mean that the variant is more transmissible or eludes vaccination.
According to a report by the South African Genomic Surveillance Network, the new variant contains more than 30 mutations in the spike protein.
According to João Paulo Gomes, “many of these mutations are in the cell binding zone, while others are mutations known to be associated with an inability to bind antibodies.”
“The problem with this new strain is that it has many more mutations than the other variants that have bothered us so far,” he stressed.
The World Health Organization (WHO) on Friday classified variant B.1.1.529, first discovered in South Africa’s Gauteng province, as a “dangerous” variant and named it “Omicron,” a letter of the alphabet.
According to the WHO, this variant has “a large number of mutations, some of which are of concern,” with preliminary data suggesting an “increased risk of re-infection” with the new SARS-CoV-2 strain compared to other variants to worry.
As defined by WHO, options of concern are associated with increased transmissibility or virulence or decreased effectiveness of social and public health interventions, diagnoses, vaccines and treatments.
The European Center for Disease Prevention and Control believes that Omicron raises “serious concerns that it could significantly reduce the effectiveness of vaccines and increase the risk of reinfection.”
After South Africa, the variant has already been found in the UK, Germany, Italy, Belgium, Hong Kong (administrative region of China), Israel and Botswana.
Portugal, which is investigating cases of infection with the new strain, will suspend flights to and from Mozambique from Monday.
Starting this Saturday, all passengers arriving on flights from Mozambique, South Africa, Botswana, Essuatini (formerly Swaziland), Lesotho, Namibia and Zimbabwe are required to comply with a 14-day quarantine upon entering mainland Portugal.
On Friday, European Union member states decided to temporarily suspend flights from seven South African countries, including Mozambique, to limit the spread of Omicron.
Covid-19 is a pandemic respiratory disease caused by the SARS-CoV-2 coronavirus, discovered at the end of 2019 in Wuhan, a city in central China.
In addition to Omicron, there are four other variants of the virus that WHO believes are of concern, including Delta, which is the dominant and most contagious virus in the world today.

Vladimir Putin has delayed the invasion of Ukraine at least three times.
Putin has repeatedly consulted with Russian Chief of the General Staff Valery Gerasimov and Defense Minister Sergei Shoigu about the invasion, Europa Press told Ukraine’s chief intelligence director Vadim Skibitsky.
According to Skibitsky, it was the Russian Federal Security Service (FSB), which is responsible for counterintelligence and espionage work, that put pressure on Gerasimov and other military agencies to agree to launch an offensive. .
However, according to the Ukrainian intelligence services, the FSB considered that by the end of February sufficient preparations had already been made to guarantee the success of the Russian Armed Forces in a lightning invasion.
However, according to Kyiv, the Russian General Staff provided the Russian troops with supplies and ammunition for only three days, hoping that the offensive would be swift and immediately successful.
The head of Ukrainian intelligence also emphasized the cooperation of local residents, who always provided the Ukrainian authorities with up-to-date information about the Russian army, such as the number of soldiers or the exact location of troops.
The military offensive launched on February 24 by Russia in Ukraine caused at least 6.5 million internally displaced persons and more than 7.8 million refugees to European countries, which is why the UN classifies this migration crisis as the worst in Europe since World War II (1939-1945). gg.). ).
At the moment, 17.7 million Ukrainians are in need of humanitarian assistance, and 9.3 million are in need of food aid and housing.
The UN has presented as confirmed 6,755 civilian deaths and 10,607 wounded since the beginning of the war, stressing that these figures are much lower than the real ones.

Life sentence for former Swedish official for spying for Russia
A Stockholm court on Monday sentenced a former Swedish intelligence officer to life in prison for spying for Russia, and his brother to at least 12 years in prison. In what is considered one of the most serious cases in Swedish counterintelligence history, much of the trial took place behind closed doors in the name of national security.
According to the prosecution, it was Russian military intelligence, the GRU, who took advantage of the information provided by the two brothers between 2011 and their arrest at the end of 2021.
Peyman Kia, 42, has held many senior positions in the Swedish security apparatus, including the army and his country’s intelligence services (Säpo). His younger brother, Payam, 35, is accused of “participating in the planning” of the plot and of “managing contacts with Russia and the GRU, including passing on information and receiving financial rewards.”
Both men deny the charges, and their lawyers have demanded an acquittal on charges of “aggravated espionage,” according to the Swedish news agency TT.
The trial coincides with another case of alleged Russian espionage, with the arrest of the Russian-born couple in late November in a suburb of Stockholm by a police team arriving at dawn in a Blackhawk helicopter.
Research website Bellingcat identified them as Sergei Skvortsov and Elena Kulkova. The couple allegedly acted as sleeper agents for Moscow, having moved to Sweden in the late 1990s.
According to Swedish press reports, the couple ran companies specializing in the import and export of electronic components and industrial technology.
The man was again detained at the end of November for “illegal intelligence activities.” His partner, suspected of being an accomplice, has been released but remains under investigation.
According to Swedish authorities, the arrests are not related to the trial of the Kia brothers.

Ukraine admitted that Russia may announce a general mobilization
“They can strengthen their positions. We understand that this can happen. At the same time, we do not rule out that they will announce a general mobilization,” Danilov said in an interview with the Ukrainska Pravda online publication.
Danilov believed that this mobilization would also be convened “to exterminate as many as possible” of Russian citizens, so that “they would no longer have any problems on their territory.”
In this sense, Danilov also reminded that Russia has not given up on securing control over Kyiv or the idea of the complete “destruction” of Ukraine. “We have to be ready for anything,” he said.
“I want everyone to understand that [os russos] they have not given up on the idea of destroying our nation. If they don’t have Kyiv in their hands, they won’t have anything in their hands, we must understand this,” continued Danilov, who also did not rule out that a new Russian offensive would come from “Belarus and other territories.” .
As such, Danilov praised the decision of many of its residents who chose to stay in the Ukrainian capital when the war broke out in order to defend the city.
“They expected that there would be panic, that people would run, that there would be nothing to protect Kyiv,” he added, referring to President Volodymyr Zelensky.
The military offensive launched on February 24 by Russia in Ukraine caused at least 6.5 million internally displaced persons and more than 7.8 million refugees to European countries, which is why the UN classifies this migration crisis as the worst in Europe since World War II (1939-1945). gg.). ).
At the moment, 17.7 million Ukrainians are in need of humanitarian assistance, and 9.3 million are in need of food aid and housing.
The Russian invasion, justified by Russian President Vladimir Putin on the need to “denazify” and demilitarize Ukraine for Russia’s security, was condemned by the international community at large, which responded by sending weapons to Ukraine and imposing political and economic sanctions on Russia.
The UN has presented as confirmed 6,755 civilian deaths and 10,607 wounded since the beginning of the war, stressing that these figures are much lower than the real ones.
