Вариант вируса, названный «SARSCoV-2, вариант202012/01»,впервые был выявлен в Соединенном Королевстве, и сейчас его циркуляция подтверждена в ряде стран Европейского ре...иона ВОЗ. Он помечен как «вариант, вызывающий обеспокоенность» (VOC), поскольку, по имеющимся данным, он более активнопередается от человека к человеку.

If you have already had COVID-19 do you still need both doses of the vaccine? Do these vaccines protect you against infection? Do they protect us against variants? WHO’s Dr Katherine O’Brien answers these questions in Science in 5 this week.
21 Dec 2021. Slideset updated regularly to include the latest data and guidance on COVID-19 vaccines, including implications of emerging SARS-CoV-2 variants
What do we know about the Delta variant so far? How can we assess our risk? What strategies should we apply to protect ourselves whether we are in a low vaccination or high vaccination setting? WHO’s Dr Maria Van Kerkhove explains in Science in 5.
Do the current batch of approved vaccines protect us from the Delta variant? What is the level of protection? If you can still get infected even after being fully vaccinated, then why should we vaccinate? WHO’s Chief Scientist Dr Soumya Swaminathan explains in Science in 5.

The overall threat posed by Omicron largely depends on four key questions: (i) how transmissible the variant is; (ii) how well vaccines and prior infection protect against infection, transmission, clinical disease and death; (iii) how virulent the variant is compared to other varian...ts; and (iv) how populations understand these dynamics, perceive risk and follow control measures, including public health and social measures (PHSM).

O Informe Semanal de Evidências sobre Variantes de Atenção do SARS-CoV-2 é uma produção organizada pelo Departamento de Ciência e Tecnologia da Secretaria de Ciência, Tecnologia, Inovação e Insumos Estratégicos em Saúde do Ministério da Saúde (DECIT/SCTIE/MS). O documento tem o objetiv...o de acompanhar e relatar as mais recentes evidências descritas em publicações científicas e
na literatura cinzenta sobre as principais variantes de SARS-CoV-2 circulantes no Brasil e no mundo, bem como as implicações destas para a saúde. Para tanto, são realizadas buscas estruturadas em bases de dados de indexação de periódicos científicos revisados pelos pares, de artigos no formato pré-print e de literatura cinzenta. Este informe tem caráter unicamente informativo e não representa
uma recomendação oficial do MS sobre a temática. Os trechos destacados em itálico no corpo do texto consistem em novas informações publicadas no período de 11 a 17 de outubro de 2021. Os demais trechos são referentes a informações já fornecidas em Informes anteriores.
