And step forward circumstances are conceivable although you might be vaccinated, regardless that they are more likely to be much less serious than if you were not, Siegel mentioned.

“Do not rely on prior an infection to fully offer protection to you and do not rely on a vaccine to fully offer protection to you, however get as a lot immunity as you’ll be able to,” he mentioned.

It is reassuring to grasp that Omicron seems to motive fewer long-term signs, Siegel mentioned.
