From Noahpinion:
Key points according to Smith [Emphasis added, mine]:
Delta, though much more transmissible, wasn’t an “escape variant”. The original, unmodified mRNA vaccines worked perfectly well against Delta.
The same is probably not true of Omicron. Sequencing and some lab studies suggest that Omicron has evolved ways to escape both acquired immunity and vaccine immunity.
That suggests that vaccine companies will need to make new booster shots against Omicron. In fact, this is easy to do, and they’re already doing this. The key is getting rapid FDA approval and getting the CDC to recommend the boosters.
The CDC was slow to recommend boosters against Delta in part because of concern over vaccine availability for developing countries, but mostly because the CDC is very parochial and didn’t trust the data on boosters and Delta that was emerging from other countries like Israel.
Far more effective than variant-specific boosters would be a universal “supervaccine” that works against all possible variants of Covid. Several labs, including Topol’s, have candidates for such a supervaccine.
Either the U.S. federal government or a group of countries needs to immediately coordinate and fund an effort to create a Covid supervaccine. This would represent our best bet at ending the pandemic once and for all.
In the meantime, Pfizer’s antiviral drug should be effective against most or all Covid variants, and represents a vital addition to our toolkit against new variants like Omicron.

Topol’s statement that mutations were unanticipated (at minute 3:48) is not strictly accurate. For an in depth discussion of this see New, Radically Different Covid Variant Getting Footholds Now as Media and Officials Remain Complacent.
