The doctors said expectations of COVID-19 vaccines need to change, waiting for an omicron-specific vaccine may not be timely and vaccine technology should continue to be developed.

But because immunity wanes over time, people need to change their expectations of COVID-19 vaccines, according to Assoumou and Dr.

"We're going to have to really think about, 'What is our goal with these vaccines?' And our goal should be to prevent hospitalization and death because I think that that's really what these vaccines can do," Assoumou said.

"We really need to calibrate, or recalibrate, what our expectations are from the vaccines," Kuritzkes said.

"The vaccines really are to prevent severe disease and death.

Kuritzkes noted that while the Israeli study showed that a fourth booster shot didn't prevent the spread of omicron, "the third shot -- a booster -- really does help." Additionally, waiting for an omicron-specific vaccine may not be timely

Doron spoke to the need for developed vaccine technology and not just relying on mRNA vaccines

"I think really the next stage needs to be looking at alternative vaccine technology that may have either more capacity to be sterilizing, so perhaps a nasal vaccine would really knock out the ability of the virus to attach to the respiratory mucosa and cause infection," she said
