mRNA vaccines give significant protection against all variants causing Covid-19: Experts


SINGAPORE - The two vaccines Singapore is using will protect significantly, but not absolutely, against all current variants of the coronavirus that causes Covid-19, say experts. To what extent, however, is where they do not agree.
The Ministry of Health said last week that all three Covid-19 variants of concern (VOCs) - strains that could cause the most harm - as well as the two variants of interest (VOIs) behind the massive surge in cases in India, have been found in community transmissions here. VOIs have the potential to become VOCs.
The three VOCs - the B117 UK variant, P1 Brazilian variant and B1351 South African variant - are of concern because they spread more easily. Though they may not cause more severe illness, there are worries that vaccines might prove less effective against them. ....

'Coronavirus has mutated more than 6,600 times'


Describing Indian variant as double or triple mutant a misnomer
Dr Maurer-Stroh said the terms double mutant or triple mutant variants used to describe the virus strains rampaging in India are therefore a misnomer, but broadly refer to the more significant mutations found in those variants.
 
Fortunately, there are only three VOCs right now. However, there are several variants of interest (VOI) which appear to exhibit some of the characteristics of a VOC, but without sufficient evidence for the moment. That may change.
They include the two variants first detected in India that are causing the huge surge in cases over the past month, he added. ....

The coronavirus that causes Covid-19 has mutated more than 6,600 times


SINGAPORE - The Sars-CoV-2 virus that sparked the Covid-19 pandemic has undergone more than 6,600 unique spike protein mutations, said Dr Sebastian Maurer-Stroh, executive director of the Bioinformatics Institute at the Agency for Science, Technology and Research (A Star).
Viruses mutate whenever there is a mistake in the replication process. This could result from an addition, a deletion or a change to its genetic code.
If that mistake increases its survival prospects, more copies of that wrong replication will survive, and sometimes overwhelm the original version.
For example, the D614G mutation which started to rise sharply in February last year is now found in all samples of the virus, no matter which variant they are. ....
