Experts have wondered if Omicron’s much-milder symptoms are the result of a naturally milder virus, patients with immunity through infection or vaccination or a combination of all three. Vaccines have two essential purposes: to prevent spread and to decrease severity. And though the mRNA vaccines clearly decrease severity of infection, especially with a recent booster, they clearly are doing little to prevent spread. This makes the mandate argument even more unconvincing — why mandate a vaccine that doesn’t prevent spread of the pathogen? Dr. Kakoto Iwasaki, world-renowned Yale immunologist, told me that she is working on a vaccine to prevent infection altogether by blocking uptake in the nasal passages.
