AstraZeneca’s ChAdOx1-nCov-19 vaccine (first dose) followed by BNT162b2 vaccine (second dose) could significantly induce higher levels of cellular and humoral immunities against the Alpha (B.1.1.7), Beta (B.1.351) and Gamma (P.1) variants of concern of SARS-CoV-2 than only homologous ...
"In view of the evolving global scenario with the emergence of new variants of concern, the situation is being watched closely in consultation with all stakeholders and an appropriate decision indicating the effective date of resumption of scheduled commercial international passenger services shall be no...
The variant was initially referred to as B.1.1.529, but on Friday was designated as a variant of concern (VOC) by the World Health Organization because of its “concerning” mutations and because “preliminary evidence suggests an increased risk of reinfection with this variant”. The WHO sys...
With the global circulation of new variants of concern, such as Omicron and its sublinages41, our findings can inform control management in other urban settings beyond NYC. Specifically, public health authorities should consider the community-level spatial dispersion of SARS-CoV-2 when designing cont...
The genome feature of SARS-CoV-2 leads the virus to mutate and creates new variants of concern. Tackling viral mutations is also an important challenge for the development of a new vaccine. Accordingly, in the present study, we undertook to identify B- and T-cell epitopes with immunogenic ...
we discuss the unprecedented challenges faced by the Brazilian public health system in the midst of the second wave of the COVID-19 pandemic, particularly regarding the collapse of the Brazilian health system and the emergence of new variants of concern (VOCs). Finally, we suggest some insights...
While new variants of concern first identified in the U.K., South Africa and Brazil can transmit more easily than other strains, experts say brief interactions with an infected person — whether they have a new variant or not — can be risky under the right circumstances. ...
protect against serious disease. Maybe a breakthrough infection might be more common with omicron but you're still likely protected against what matters: serious disease, hospitalization and death. So it may be that the vaccine is the key to keeping this and other variants at bay," said Ada...
BEIJING, Jan. 31 (Xinhua) -- New variants of coronavirus are on the rise and spreading around the world. The list of countries that have identified infections with the new variants has been growing. New cases of COVID-19 variants have been confirmed in many countries, including the United ...
However, Pekosz notes that the EG.5 variant may not be the sole reason for the summer uptick. “When you have a new variants, and cases creeping up, there’s always concern about whether that variant could be driving the increase,” says Pekosz. ...
