Moderna: Existing Vaccines will Struggle30 Nov 2021 18:53
With the rise of Omicron we are getting mixed messages from various parts of the community. Some politicians and public health experts are pushing for a; do not panic take your booster approach. Top scientists and clinicians heading up the fight against covid are talking of new vaccines and the potential inadequacy of the current vaccines. This can be confusing.
Moderna chief Stephane Bancel predicts that existing vaccines will struggle with Omicron and it could be months before the right variant-specific jab is produced at scale (see excellent article in the FT today). Then there is the obvious issue of distribution, vaccine take-up and finally the time it takes for the immune system to provide sufficient protection post-jab. Although he advocates for waiting for the data, he says that all the scientists that he's spoken to have said "This is not going to be good" [1].
Why then the mixed message? This is based on our understanding that we can provisionally increase antibodies to some extent by taking multiple boosters of current, (potentially mismatched against Omicron), vaccines – this is while we wait for new vaccines to be developed. Hence, we get some defence which can be further strengthened by more boosters and lead to slowing the impact of Omicron. Most likely we will see many Governments around the world pushing for a) an increase in the number of boosters and b) reducing the time between one jab and the next. By the time a new vaccine is developed, it could be months and the current suggestions from Gauteng indicate that there will be a doubling of hospital cases per week.
This is a multipronged approach – an urgency to get boosters administered, return of masks and use of PCR with potential social distancing and washing hands etc. on the horizon if we receive negative feedback. What this means for Synairgen is that there was talk of Covid19 dying out by the time that SNG001 is given EUA. This situation has categorically changed and there is a strong need for SNG001.
Merck's molnupiravir wasn't great to begin with and there was a lot wrong with it, I'm not sure what the outcome will be but either way it bodes well for SNG.
