Covid-19: vaccine-dependent immune response to booster doses, study says – News

Published

on

The study, published today in the British medical journal The Lancet, analyzed the results of additional dose injections in people who took two doses of Oxford / AstraZeneca vaccines, used in over 180 countries, and Pfizer / BioNtech, in over 145 countries. and it was concluded that these booster doses are “safe and enhance the immune response.”

However, they have not been found to be more effective in “protecting against infection or serious illness.”

“The side effect data demonstrates that the seven vaccines analyzed are safe for use as third doses, with acceptable levels of secondary inflammatory effects such as pain at the site of vaccination, muscle pain and fatigue. Astrazeneca, only AstraZeneca, Pfizer-BioNtech, Moderna, Novavax, Janssen and Curevac achieved the same result after two doses of Pfizer-BioNtech, ”said researcher Paul Faust from University Hospital in Southampton, UK.

As a starting point, it is recognized that the effectiveness of these vaccines diminishes over time.

The third doses were given to study participants 10–12 weeks after they received the second dose of vaccine.

The increase in antibody production against the protein that the SARS-CoV-2 virus uses to enter cells ranged from 1.8 to 32.3 for people who took two doses of AstraZeneca, and 1.3 to 11.5 times for people. vaccinated by Pfizer / BioNtech. with a “significant response” in the form of an increase in immune T cells in various combinations.

“It is important to note that the results only relate to the use of these vaccines as a booster for primary vaccination and the immune response achieved up to 28 days later. memory. We are also studying the effect of two vaccines on people who took the booster dose seven to eight months later, but the results will not be available until next year, “he added.

The study involved 2878 people aged 30 and over. More than 900 reports reported more than a thousand side effects in addition to the most common (fatigue, headache, and pain at the injection site), 24 of which were serious.

The former FIFA employee says she was the victim of harassment and still does not know if Miguel Macedo was punished.

The young man, whose name has not been released, filed two complaints against Miguel Macedo over a year ago. FIFA mediator says he has evidence of abuse, but agent remains in body

A former FIFA employee, whose identity is unknown, told The New York Times whether Miguel Macedo, who is in charge of the FIFA Legends program, was punished for sexually harassing her.

According to the North American newspaper, the claims of a young woman who filed a complaint more than a year ago were confirmed by a FIFA mediator who had access to details of the behavior of the Portuguese, who maintains good relations with President Gianni Infantino.

In 2018, the former employee joined the legal department of the organizations of the governing body of world football, under the tutelage of Miguel Macedo, in charge of the FIFA Legends project, which is dedicated to the creation of activities carried out by former – world famous footballers.

That same year, according to The New York Times, the woman was subjected to several acts of sexual harassment by Miguel Macedo, who instructed what clothes to wear and sent sycophant messages to the young woman.

The victim said that one day she was asked to go to the room of the accused agent early in the morning. In another situation, on evaluation, a young woman was groped by Miguel Macedo and became the object of provocative comments. “It was one of the worst days,” said a young woman quoted by the NYT.

Despite a complaint filed by FIFA head of human resources Kimberly Morris, the organization did not take it into account, and the Portuguese agent ignored the investigation or even possible punishment.

The former FIFA official then met with the head of FIFA’s member associations, Joyce Cooke, who launched an investigation process, but months passed with no action. “I want to let you know that Miguel Macedo unexpectedly returned to the office today, and it’s becoming unbearable for me to be here. I don’t know how we can continue to stay in this unhealthy environment,” the victim emphasized in an email. addressed, later to Joyce Cook.

However, Nirmala Diaz, FIFA’s mediator, has produced a report stressing that there is sufficient documentary evidence to address the woman’s complaints against Miguel Macedo (Figo’s former agent), who is still employed by FIFA.

Europa tem alternativas para substituir parcialmente o gás russo, defendem especialistas – Atualidade

Published

on

Em declarações à France-Presse (AFP), especialistas consideraram “improvável” a interrupção total do abastecimento de gás natural russo, mas apontaram alternativas.

“Os gasodutos vêm da Noruega, Argélia e Azerbaijão, mas esses países não têm capacidade de produção adicional”, indicou Thierry Bros, professor da Sciences Po Paris.

Assim, prosseguiu, a Europa está de olhos postos no fornecimento de gás natural liquefeito (GNL), que pode chegar por navio, proveniente de qualquer parte do mundo.

Do outro lado do Oceano Atlântico, os Estados Unidos anunciaram que estão a trabalhar em “fornecimentos alternativos, que cobrem uma maioria significativa de potenciais cortes” no fornecimento de gás russo à Europa.

Nesse sentido, o Presidente Joe Biden tem já uma reunião agendada com o Emir do Catar, o maior exportador mundial de GNL, na próxima semana.

Também a Australia disse estar pronta para enviar gás natural para a Europa.

“Em termos de volumes [de GNL], os três gigantes, atualmente, são o Catar, a Austrália e os Estados Unidos”, indicou Vincent Demoury, delegado-geral do Grupo Internacional de Importadores de Gás Natural Liquefeito (GIIGNL).

“São sobretudo aqueles três países que teriam flexibilidade para produzir mais, ou redirecionar para a Europa volumes tradicionalmente direcionados para outros mercados”, acrescentou.

No entanto, “não é possível substituir todo o gás russo por GNL”, advertiu Thierry Bros.

As capacidades de regaseificação na Europa (incluindo o Reino Unido) são de cerca de 19 mil milhões de metros cúbicos (bcm) por mês, dos quais cerca de 8 bcm, em média, já estão utilizados, sobrando cerca de 11 bcm de capacidade para uso.

Aquele valor, apontou o especialista, nãoé suficiente para compensar os cerca de 14 bcm por mês vindos da Russia.

Este inverno, as reservas de gás na Europa estão baixas e os suprimentos da Rússia atingiram um nível historicamente baixo este mês.

Ainda assim, os especialistas duvidam que a Russia chegue ao ponto de fechar completamente a torneira.

“A suspensão total das exportações de gás continua a ser o menos provável dos cenários”, considerou o Eurasia Group.

Para o grupo de consultoria e pesquisa de risco político, “isso acarretaria sérios riscos de longo prazo para a estabilidade financeira e influência política da Rússia na Europa, já que a União Europeia, provavelmente, responderia agressivamente, diversificando o seu suprimento de energia”.

“Os russos não têm interesse em interromper as entregas”, realçou Thierry Bros.

Além do interesse financeiro, apontou, a manutenção das suas entregas “permite criar discordância na Europa”, uma vez que a Rússia poderia continuar a abastecer alguns países (Alemanha, Grécia, Hungria, por exemplo), mas outros não (Polónia, Lituânia) .

Perante uma crise que ilustra a forte dependência energética da Europa em relação ao seu vizinho russo, os 27 Estados-membros da União Europeia (UE) estão a ponderar soluções a médio prazo.

O primeiro caminho, que acaba de ser discutido numa reunião informal dos ministros da energia europeus, em Amiens, França, passa por estabelecer “regras mais rígidas sobre armazenamento de gás”, conforme indicou a ministra francesa para a Transição Ecológica, Barbara Pompili.

O modelo francês, que garante o preenchimento das reservas para o inverno, poderia, assim, ser ampliado.

Também o Luxemburgo sugeriu a assinatura de contratos de fornecimento de longo prazo com paises produtores considerados mais fiáveis ​​do que a Russia.
