Omicron variant, the battle is not lost. But you need the third dose

The first data on the Omicron variant are very heterogeneous and absolutely preliminary, but they are all fairly in agreement in saying that this new variant is able to evade, to a certain extent, the neutralizing antibodies produced by vaccinated and / or cured subjects. A recent report tells of how the Omicron variant was able to infect 7 young subjects despite the 3 doses of the vaccine, who fortunately only had mild or moderate symptoms.
