Nanopore Sequencing SARS-CoV-2 genome in Qatar
(
Qatar University Press
, 2020 , Poster)
Background: The current pandemic, COVID-19, is cause by an RNA coronavirus that was recently identified as SARS-CoV-2. RNA viruses tend to have a high mutation rate; the rate is around a million times greater than that of ...
Within-host diversity of SARS-CoV-2 in COVID-19 patients with variable disease severities
(
Qatar University Press
, 2020 , Poster)
Background: The ongoing pandemic of SARS-COV-2 has already infected more than eight million people worldwide. The majority of COVID-19 patients are either asymptomatic or have mild symptoms. Yet, about 15% of the cases ...
Waning mRNA-1273 Vaccine Effectiveness against SARS-CoV-2 Infection in Qatar
(
Massachussetts Medical Society
, 2022 , Other)
In early 2021, Qatar launched a mass immunization campaign with the mRNA-1273 (Moderna)1 vaccine against coronavirus disease 2019 (Covid-19).2 We assessed the persistence of real-world vaccine effectiveness against severe ...
mRNA-1273 COVID-19 vaccine effectiveness against the B.1.1.7 and B.1.351 variants and severe COVID-19 disease in Qatar
(2021 , Article)
The SARS-CoV-2 pandemic continues to be a global health concern. The mRNA-1273 (Moderna) vaccine was reported to have an efficacy of 94.1% at preventing symptomatic COVID-19 due to infection with ‘wild-type’ variants in a ...
Evaluation of reverse transcription-loop-mediated isothermal amplification (RT-LAMP) for detecting SARS-CoV-2 in clinical, environmental and animal samples.
(
Qatar University Press
, 2020 , Poster)
Background: First described 20 years ago by Notomi et al., the loop-mediated isothermal amplification (LAMP) assay is robust, rapid and straightforward, yet retains high sensitivity and specificity. These features have ...
Protection against the omicron variant from previous SARS-CoV-2 infection
(
Massachusetts Medical Society
, 2022 , Other)
Natural infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) elicits strong protection against reinfection with the B.1.1.7 (alpha),1,2 B.1.351 (beta),1 and B.1.617.2 (delta)3 variants. However, the ...
