Some on this forum have steadfastly maintained that vaccination does not affect the transmission of the Omicron variant. You know who you are.
Now we will see if clear evidence that you are wrong can change your mind. CDC has been tracking data by full vaccination status and has just released what it has for the last two months of 2021 when the Omicron variant was by far the predominant strain (95%). Here are the results.
The data shows significant increases for all groups as the year ended but with the vaccinated and boosted at much lower levels than the unvaccinated. In November, unvaccinated adults aged eighteen and over had 13x the risk of testing positive for Covid and 68x the risk of death from Covid compared to those fully vaccinated and boosted.
The conclusion from such data is undeniable. Vaccination not only makes Omicron infection less severe; it also greatly reduces the risk of becoming infected. The infected spread the disease to others. Say goodbye to yet another reason to avoid vaccination and to oppose lifesaving public health mandates.
