It’s been reported the COVID-19 omicron variant can infect nearly everyone. However, according to the World Health Organization, less severe symptoms occur for vaccinated people compared to unvaccinated individuals.

As far as previous infection protecting someone, Dr. Angela Hewlett with Nebraska Medicine said even though a person was sick during the delta surge, that immunity may not protect them from omicron.

“Now what we have seen are people who have delta and then actually relatively soon, within a month or two, actually do contract omicron as well,” Hewlett said, “and so the people that had some immunity from delta, it’s not necessarily protective against omicron.”

Hewlett said the best protection currently available to fight the virus includes masking in public and getting vaccinated to prevent hospitalization.

Last week, the Nebraska Public Health lab reported 77 percent of new COVID-19 cases in Nebraska were omicron variant cases – making it the dominant strain in the state.
