Omicron variant reduces hope of herd immunity to Covid-19

As the new variant of Omicron spread rapidly around the world, many experts had hoped it would eventually help create herd immunity against Covid-19. However, for now, experts admit that Omicron will not help create herd immunity because the ability of this variant to infect people who have been vaccinated or previously infected is far beyond that of previous variants. .

“A really unexpected challenge is that the virus has mutated so rapidly in relation to the immune system. In my opinion, most scientists didn’t think that these immune system-escaping variants would emerge so quickly. We also thought it was possible before, but it will take a long time,” said Erin Mordecal, an associate professor of biology at Stanford University.

People who have been vaccinated against Covid-19 are still at risk of contracting the Omicron variant

Experts say Omicron has provided further evidence that the corona virus will continue to find a way to break through the human immune system.

“Reinfection also worries us because it means that even if you don’t have symptoms, you can still infect others. And given the rate at which the virus is spreading and there’s still a large population that can get it and get sick, we think it’s very concerning,” said Dr. Carolina, comments.


Instead of herd immunity, many experts claim that there is more evidence that vaccines and past infections can help boost immunity, helping people infected or re-infected with Covid-19 do not become seriously ill.

“I think some form of SARS-CoV-2 is likely to be with us for a long time, but hopefully there will be milder outbreaks, with fewer hospitalizations and deaths, back to normal. should be more like a seasonal Pandemic and related to flu and cold seasons,” said Ms. Mordecal.

Although many people still hold out hope of achieving herd immunity to Covid-19, medical experts believe that in the future, although Covid-19 is not completely eradicated, it will become a controllable challenge. no longer a crisis.
