"The welcome news for most people who are vaccinated and boosted is that omicron infections often mimic the symptoms of the common cold. Those with two shots of vaccine, but no booster, also appear to fare relatively well, though they may develop more intense symptoms that may last longer, experts said.
Of the 205 million Americans who have been vaccinated, about 66 million, or 32 percent, have received a booster dose, according to the Centers for Disease Control and Prevention.
In a series of Twitter posts, Craig Spencer, who teaches emergency medicine at Columbia University Medical Center, said every boosted patient he has seen in the emergency room has had no difficulty breathing or shortness of breath. Those who have had two doses of either the Pfizer or Moderna vaccines also have had mild symptoms, he said, “but more than those who had received a third dose.”
But almost every patient who had to be hospitalized was unvaccinated, he said.
“No matter your political affiliation, or thoughts on masks, or where you live in this country, as an ER doctor you’d trust with your life if you rolled into my emergency room at 3am, I promise you that you’d rather face the oncoming Omicron wave vaccinated,” Spencer wrote."
