" ... Just to make matters more interesting, the virus is not waiting for us to get our act together. New variants are emerging that seem to spread faster. They may slow down progress when time is not on our side, economically speaking. ... "
" ... New variants of SARS-CoV-2 are an unexpected spanner in the works as countries around the world establish their vaccine distribution regimes. These new variants, which may be more contagious from early observations, pose new challenges in the global fight against Covid-19. SARS-CoV-2 variants cause problems for the afflicted countries and present dangers for all countries in the battle against Covid-19. ... "
" ... Second, expand current efforts to sequence and survey new variants. We need to be prospecting the entirety of the genome, as well as the entirety of the biosphere, for alterations that encourage immune modulation. And we need to be prepared to adapt our vaccines to an adapting virus, as we do with seasonal flu. Over the course of the pandemic, not nearly enough emphasis has been placed on thinking longer term about the bigger picture. That has cost us dearly. We can’t afford to make the same mistake with these variants. Not when we know exactly what to do to protect ourselves against them. ... "
" ... The U.K. and South Africa also happen to also be where researchers have discovered variants of the Sars-CoV-2 virus, which causes Covid-19. These variants have raised concerns among public health officials because research indicates that they’re more contagious than previously known strains. The locations of these trials are enabling the company to determine how its vaccine will fare against these mutations. For now, Novovax is "feeling very comfortable that our vaccine should work well” said president of R&D Greg Glenn. The company previously dealt with mutations related to its flu vaccine and saw “no impact on immunogenicity” in trials, Glenn said. ... "
" ... The United Kingdom and South Africa discovered new SARS-CoV-2 variants in their domestic Covid-19 cases. The variants were found using genome sequencing techniques that analyze the structure of the virus and discern mutations. These genome sequencing techniques were regularly used worldwide at the start of the pandemic when we knew less about the virus, but they have since fallen by the wayside. The US and other countries should follow the UK and South Africa’s footsteps in terms of revamped genome sequencing regimes, as the next variant may be hiding in our backyard. ... "
