RE: New Variant Testing22 Feb 2021 19:07
From the last RNS 02.02.2021:
"Novacyt's bioinformatics surveillance group has worked with a global network of virologists tracking variants to identify the mutations, or Single Nucleotide Polymorphisms (SNPs), critical to each variant.
From this analysis, Novacyt has developed and patented the SNPsig® portfolio, which is one of the first commercially available for variant detection.
The first three SNPsig® assays, launched today, enable the identification of the non-variant virus and the UK, South Africa or Brazil variants, as well as any variant carrying the N501Y mutation."
Specifically these RUO assays are:
SNPsig SARS-CoV-2 (N501Y) Detection Profile - Variants with N501Y mutation (UK, SA & Brazil)
SNPsig SARS-CoV-2 (201/501Y.V1) Detection Profile - UK
SNPsig SARS-CoV-2 (20H/501Y.V2) Detection Profile - SA
Today via twitter we were advised that another RUO assay had been released:
SNPsig SARS-CoV-2 (20J/501Y.V3) Detection Profile Brazil variant -

So now they can detect all 3 mutations at once, or one variant at a time.
For virus sequences gathered inside or outside the UK, it will be added to (and available to all via) the worldwide GISAID (Global Initiative on Sharing Avian Influenza Data) database.
Many nations have not been contributing virus sequences to the database, but now recognise the value of virus sequence contribution.
This is because they continually need reassurance the vaccines they provide to their citizens are still effective against all mutations.
Also from the last RNS:
"The tracking of variants could also contribute to the effectiveness of vaccination efforts, especially if, as described in recent publications, the emergence of variants may have an impact on vaccine efficaciousness. The SNPsig® assays offer the ability to track variants on-site and to generate a result in hours, compared to the current approach of next generation sequencing, which is typically constrained by limited capacity, cost and an off-site multi-day turnaround." ref https://jamanetwork.com/journals/jama/fullarticle/2776039
Only a government that does not have the health of the people at heart will not be willing to test which variants are circulating in the population, (and which new threats are emerging).
It won't be long before we hear what assistance WHO are willing to provide to poorer nations, who will be needing portable testing equipment for fast answers,

I'm waiting for the WHO to recognise the new SNP assay's ASAP.
