"All of the variants prior to this, we were not seeing a lot of reinfection with the current variant," Arwady said. The two new studies start to explain why, all of a sudden, these new variants have started to spread so quickly. The same may be said for someone who has experienced a breakthrough illness in 2022, even if it was Omicron that was the root cause, as there's a good chance that future iterations of SARS-CoV-2 may impact any immunity you may have built up.
