We simply don't know. Omicron hasn't been around long enough to make declarative statements. That being said, I think there is still reason for hope: 1. Omicron seems more infectious, but less lethal. Science still needs to collect more data, but the evidence seems to be leaning in this direction. [1] 2. Two shots of an mRNA vaccine still seem to show some protection against hospitalization and death. [2] 3. Three shots of an mRNA vaccine seem to be nearly as effective against Omicron as two shots were against previous strains. [3] So, from my reading, the best case scenario is that Omicron becomes the dominant strain, is less lethal in unvaccinated populations, and no more dangerous to vaccinated populations, assuming booster shots are administered. If this is all true, it's a very good development. The caveat is that all of these links are news reports, not scientific papers. I'm not a doctor, and neither are the people who wrote these, so they might be blowing smoke. Also, it's common for vaccines to require multiple boosters before immunity "takes hold." The polio vaccine is given at 2 months, 4 months, 6-18 months, and 4-6 years, but then you're pretty much good. COVID might be defeated by a three-shot course. It might require yearly vaccinations.
