laura: shocking that the pfizer ceo doesn t want to put an end. joining me now is doctor the yale school of epidemiology. doctor is, what you make of this? it is a weak variant but no, we don t want it to spread. it s a week variant, not wrong about it being more transmissible. it s less transmissible. the fact is the transmissibility index has been studied by a very smart professor in france, who calculated that it transmits ability is comparable to the delta variant and it is about a third of what delta is. it s less transmissible than delta. in fact we have a lot of herd immunity in the united states. perhaps two-thirds of americans have had covid. it s not going to be fertile ground to spread against adult appeared as much as we might want to because it is so mild,
each winter. laura: we need it or does moderna need it? what is the evidence of any of this? the omicron the b 11529 variant has 30 mutations. the domain has been changed with ten mutations there. it s not going to be as infectious. the early reports from dr. fantini in france indicates the transmissibility index of the omicron variant is far less than delta. so it doesn t look like it s going to be a dominant strain. i think it will be like the lambda and the epsilon variants described in the most recent year of covid-19. it will be a minor variant. i wouldn t be looking for it wrapping up on new vaccines or
will, as a regular thing. laura: we need it or does moderna need it? what is the evidence of any of this? the oma cron variant looks like an evolutionary mistake a 30 mutations in the spike protein, three deletions and one insertion, almost certainly the receptor body domain has been changed, it is not going to be as infectious. the early reports from the university to indicate the transmissibility index of the oma cron variant is less and delta. doesn t look like it will have the evolutionary efficiency to become a dominant strain. it will be like the lambda and epsilon variants previously described in the recent year.
Just one month before Christmas, Portugal is going through the fifth phase of the Covid-19 pandemic, with an increase in infections, but the pressure on health.
