. Abstract. . Purpose. Omicron is rapidly spreading as a new SARS-CoV-2 variant of concern (VOC). The question whether this new variant has an impact on SARS-CoV-2 rapid antigen test (RAT) performance is of utmost importance. To obtain an initial estimate regarding differences of RATs in detecting omicron and delta, seven commonly used SARS-CoV-2 RATs from different manufacturers were analysed using cell culture supernatants and…

A new SARS-CoV-2 variant of concern (VOC) assigned to the lineage B.1.1.529, designated as Omicron, has been reported to the World Health Organization (WHO) by South Africa scientists on November 24th, 2021 (World Health Organization 2021). The first cases of SARS-CoV-2 infection caused by the Omicron variant were reported to originate from Botswana and South Africa (World Health Organization 2021). In Belgium, the first case of SARS-CoV-2 infection caused by the Omicron variant was identified in late Novem…

…efore, understanding hybrid immunity (ie, immunity derived from infection plus vaccination) is crucial to guide future vaccination policies. We found that vaccination provided additional protection to that induced by past infection during the gamma (P.1) and delta (B.1.617.2) variant waves of the pandemic in Brazil.1 With the emergence of the omicron (B.1.1.529) variant, vaccine effectiveness appears to decay,2,3 but protection in individuals who have been previously infected and vaccinated remains unknown.

The SARS-CoV-2 B.1.1.529 (omicron) variant, divided in five lineages (BA.1/BA.2/BA.3/BA.4/BA.5), harbors numerous spike protein mutations particularly in the receptor-binding-domain (RBD). Recent studies showed that the omicron variant resists to the majority of RBD-targeting monoclonal antibodies (mAb) [1]. Sotrovimab, a pan-sarbecovirus neutralizing mAb recently authorized, seems to remain efficient to neutralize omicron variant [1,2]. However, as it targets a single epitope, the risk of developing resist…

Objectives: In industrialized countries that have experienced major extensive epidemics of Omicron (B.1.1.529), substantial fraction of the population was exposed including children.Methods: Statistical association between the detection of at least one hepatitis case among children and the cumulative number of Omicron cases (B.1.1.529) was examined. Thirty-eight countries that belong to the Organization for Economic Cooperation and Development and Romania were included for the analysis.Results: Of the total…

…ibody levels post-vaccination and the emergence of variants of concern (VOCs) capable of evading protective immunity has raised the need for booster vaccinations. However, which combination of COVID-19 vaccines offers the strongest immune response against Omicron variant is unknown.MethodsThis randomized, subject-blinded, controlled trial assessed the reactogenicity and immunogenicity of different COVID-19 vaccine booster combinations. 100 BNT162b2-vaccinated individuals were enrolled and randomized 1: 1 to…

With the rapid wave of Omicron (B.1.1.529) SARS-CoV-2 cases detected worldwide and the significant mutation profile of this Variant of Concern (VOC), questions have been raised about its impact on SARS-CoV-2 tissue tropism and viral load. As Omicron more adeptly replicates in the upper respiratory tract than previous variants[1], it has been proposed that saliva or oral specimens may detect Omicron with greater sensitivity than those from the nasopharynx[2], although evidence for this to date has not includ…

Older patients in Israel who received a fourth dose of the BNT162b2 (Pfizer-BioNTech) SARS-CoV-2 vaccine were more than 3 times less likely to develop severe COVID-19 than those who received only 3 doses. But while protection against severe disease did not wane during the testing period, protection against confirmed infection appeared short-lived.

Nature Medicine, Published online: 10 May 2022; doi:10.1038/s41591-022-01855-7. Estimates from a new modeling study suggest that current levels of vaccine coverage in China are insufficient to prevent overwhelming the healtcare system, and that the current wave of Omicron transmission could result in up to 1.55 million deaths.

AbstractBackgroundThe Omicron variant of SARS-CoV-2 evades immunity conferred by vaccines and previous infections.MethodsWe used a Cox proportional hazards model and a logistic regression on individual-level population-wide data from the Czech Republic to estimate risks of infection and hospitalization, including severe states.ResultsA recent (≤ 2 months) full vaccination reached VE 43% (95% CI: 42-44) against infection by Omicron compared to 73% (CI: 72-74) against Delta. A recent booster increased VE to…

For the period of predominance of SARS-CoV-2 Omicron variant in Slovenia, February to March 2022, we estimated mRNA vaccine effectiveness (VE) against severe acute respiratory infection (SARI) COVID-19 using surveillance data. In the most vulnerable age group comprising individuals aged 65 years and more, VE against SARI COVID-19 was 95% (95% CI: 95–96%) for those vaccinated with three doses, in comparison to 82% (95% CI: 79–84%) for those vaccinated with two doses.…

. Background. Omicron subvariant BA.2 circulation is rapidly increasing globally. . . Aim. We evaluated the neutralising antibody response from vaccination or prior SARS-CoV-2 infection against symptomatic infection by BA.2 or other variants. . . Methods. Using 50% plaque reduction neutralisation tests (PRNT50), we assessed neutralising antibody titres to BA.2, wild type (WT) SARS-CoV-2 and other variants in Comirnaty or CoronaVac vaccinees, with or without prior WT-SARS-CoV-2 infection. Titres we…

We compared vaccine effectiveness against severe COVID-19 between December 2021 and March 2022 when Omicron BA.1 and BA.2 were the dominating SARS-CoV-2 variants in Scania county, Sweden. Effectiveness remained above 80% after the transition from BA.1 to BA.2 among people with at least three vaccine doses but the point estimate decreased markedly to 54% among those with only two doses. Protection from prior infection was also lower after the transition to BA.2. Booster vaccination seems necessary to maintai…

We assessed the protection conferred by naturally-acquired, vaccine-induced and hybrid immunity during the concomitant Omicron and Delta epidemic waves in France on symptomatic infection and severe COVID-19. The greatest levels of protection against both variants were provided by hybrid immunity. Protection against Omicron symptomatic infections was systematically lower and waned at higher speed than against Delta in those vaccinated. In contrast, there were little differences in variant-specific protection…
