The caveat is that virtually every new variant since 2022 has simply been placed under the Omicron umbrella label, when some of them are more different from one another than the previous variants of concern were from the original variant.

>Complaints about scientists "not being 100% certain" and "they keep changing what they're saying" are red flags revealing people who do not understand how science works
It's not that deep. If you're averse to non-personal questions, this isn't the correct sub.

I think this comparison was probably because the viral polymerases encoded by coronaviruses are less prone per cycle to replication errors that cause mutations than some other viruses, such as influenza viruses. So for each instance at a molecular level of a polymerase replicating an mRNA sequence, a mutation is more likely for influenza viruses than for coronaviruses.
At the same time, an extremely infective virus like SARS-CoV-2 (especially with newer variants) will produce so much viral load that there becomes more opportunity for mutations per infection. Combine that with far more individuals being infected with SARS-CoV-2 each year than influenza, and you have SARS-CoV-2 mutating at a much faster rate.
Stopping the spread of the virus would be the most effective strategy to stop the continued development of new mutations.

This is kind of similar to the reverse process in plants where CO2 is taken up and O2 is released. The oxygen in the O2 molecules is not derived from the CO2 taken up for photosynthesis, but instead from the H2O molecules that are also involved in the photosynthesis process. The oxygen molecules in the CO2 molecules are mainly used for the synthesis of sugars, while the photosynthesis process involves water being split into separate hydrogen and oxygen ions. The hydrogen ions are used as part of the process for splitting the CO2 into carbon and oxygen, while the oxygen ions are released from the plant. The origin of the released O2 from the H2O instead of the CO2 has been determined through controlled experiments where the inbound H2O and CO2 contained a different isotope of oxygen.

Reply to comment by SnooPuppers1978 in Study finds Omicron variants of the SARS-CoV-2 virus which appeared at the end of 2021 have marked genetic differences from the ancestral SARS-CoV-2. The many, distinct mutations in their infection machinery have enabled them to escape from antibodies elicited from the original series of vaccines. by MyLifeisAsaJoker
Perhaps immune imprinting could also be lessened with the use of highly effective adjuvants that enhance and broaden immune responses, like Matrix-M or CpG 1018.

In some cases, an infection with one virus can temporarily prompt higher production of interferons, which are innate immunity signaling molecules that are involved in antiviral defenses.
