British concern about the emergence of a new strain of Corona in South Africa

Public health officials in Britain have expressed serious concern about a new strain of coronavirus that has recently spread in South Africa, because it contains twice the number of mutations in the delta strain, including those associated with avoiding an immune response.

The British Health Security Agency said, Thursday, November 25, 2021, that the strain called “B1.1.529” contains a so-called “spike protein” completely different from the protein found in the original Corona virus that Covid-19 vaccines are designed to combat. .

Avoiding an immune response

The new strain carries mutations that are likely to evade the immune response resulting from both previous infection and vaccination, as well as mutations associated with increased infection.

Scientists said that laboratory studies are needed to assess the possibility that the mutations will result in a significant decrease in the effectiveness of vaccines.

Earlier Thursday, South African scientists said they had discovered the new strain of COVID-19 in small numbers, and were working to understand its possible implications.

Scientists told a press conference that this strain contains a “very unusual set” of mutations, which is cause for concern, because they can help the strain evade the body’s immune response and make it more transmissible. The new strain was also found in Botswana and Hong Kong.

New cases of the breed

The British Health Security Agency said that no cases of this strain had been discovered in Britain, and that its scientists were in contact with their colleagues in South Africa; to view their data.

As European countries expanded the distribution of booster doses against “Covid-19”, and began plans to vaccinate young children Thursday, as the continent resists an increase in cases, amid mounting concerns about the economic repercussions of this increase.

The government of the Czech Republic declared a state of emergency for 30 days, due to the high number of cases of coronavirus, while Germany exceeded the 100,000 mark of death from the disease.

Europe is at the center of the latest wave of the Covid-19 pandemic, with countries on the continent detecting one million new infections every two days, and currently recording nearly two-thirds of new infections worldwide.

The European Commission proposed, on Thursday, that residents of the European Union receive booster doses if they want to travel to another country within the bloc next summer, without the need to undergo tests or quarantine.

Availability of booster doses

In France, the authorities announced that the booster doses would be available to everyone over the age of 18, rather than being limited to people over 65 and those with underlying health problems.

Many countries are rolling out or expanding booster doses, although the World Health Organization wants the world’s most vulnerable people to be fully vaccinated first.

On Wednesday, the European Center for Disease Control and Prevention recommended the use of booster doses for all adults, with priority given to those over the age of 40. There is also an increasing tendency in some European countries to vaccinate young children.

On Thursday, the European Union’s drug control body approved the use of the Pfizer and Biontech vaccines to vaccinate children aged five to 11 years at lower doses, after it was authorized for use in children under 12 years of age in May. The European Commission is expected to issue its final decision on Friday.

Poland, Hungary and the Czech Republic are preparing to vaccinate young children after approval by the European Medicines Agency, although delivery of smaller doses will not be available until December 20.

In France, where the number of infections doubles every 11 days, Health Minister Olivier Veran said he would ask health regulators to study whether children aged five to 11 should be vaccinated.

2 weeks closed

Slovakia entered a two-week lockdown on Thursday, after neighboring Austria began lockdown on Monday, as the country with one of the lowest vaccination rates in the European Union reported critical hospitalizations and new infections topping global charts.

In the Netherlands, the number of hospitalized COVID-19 patients has reached levels the country has not seen since early May. Experts have warned that hospitals will reach full capacity in just over a week if the outbreak is not contained.

In Portugal, one of the world’s most vaccinated countries, the authorities re-imposed some restrictions to stop the increase in cases of “Covid-19”, and the authorities ordered all passengers coming to the country, even those who have received the full vaccination, to show a negative test that proves that they are free of the disease. their arrival.
