Are Breakthrough Cases Being Reported With Bivalent COVID Booster? Top Doc Says Yes

Chicago's top doctor said there have been reported of breakthrough COVID infections in people who have received the new bivalent COVID booster and there's a reason for that.

"We have seen some breakthrough cases just like we have every time... since the beginning of COVID," Chicago Department of Public Health Commissioner Dr. Allison Arwady said Tuesday, adding that "it is definitely related to the newer strains."

Arwady referred to the changing dynamics of variant proportion in the Midwest and across the U.S., with the BA.5 omicron subvariant quickly losing its hold as the dominant strain.

BA.5 May Not Be the Dominant Variant Much Longer. Here's Why and What That Means

The BA.5 omicron subvariant has been the dominant COVID variant in the U.S. for months, but its reign could soon be over.

That's because two descendants of the BA.5 strain could potentially overtake it.

This comes as new variants continue to emerge, including the BN.1, which has now been added to the Centers for Disease Control and Prevention's weekly tracker.

What to Know About Quarantine, Isolation and Testing for COVID Ahead of the Holidays

With concerns of a "tripledemic" on the rise ahead of the holiday season, and several Chicago-area counties under heightened COVID alert levels, what should you know if you test positive for COVID or come into contact with someone who has?

The Centers for Disease Control and Prevention issued changes to its COVID guidelines over the summer, changing the recommendations for quarantine, social distancing and even testing.

Since then, bivalent COVID booster shots have been administered, but a rise in RSV and flu, coupled with continued COVID cases have left some worried.

Moderna Announces New Data on Effectiveness of Bivalent COVID Booster

Moderna on Monday revealed its newest trial data showed its bivalent COVID booster shots "elicited a superior neutralizing antibody response against Omicron BA.4/BA.5 variants" when compared to its original vaccine and booster shots.

"We are pleased to see that both of our bivalent booster vaccine candidates offer superior protection against Omicron BA.4/BA.5 variants compared to our original booster, which is encouraging given COVID-19 remains a leading cause of hospitalization and death globally. In addition, the superior response against Omicron persisted for at least three months after the mRNA-1273.214 booster," Stéphane Bancel, Moderna's chief executive officer, said in a statement.

Bancel also noted that the data appeared to indicate the bivalent shots showed protection against the new BQ.1.1 subvariant currently growing in numbers in the U.S.

"Our bivalent boosters also show, in research assays, neutralizing activity against BQ.1.1, an increasingly dominant emerging variant, confirming that updated vaccines have the potential to offer protection as the virus continues to evolve rapidly to escape our immunity," Bancel said.

Doctors Urge Vaccinations as Respiratory Viruses Circulate Ahead of Holiday Season

Health officials across the Chicago area are urging people to get vaccinated ahead of the colder weather, especially with cases of RSV and the flu rising.

Respiratory viruses such as the flu, RSV and COVID-19 are "spreading rapidly" across Illinois, the state's Department of Public Health said earlier this week.

Illinois health officials are warning that respiratory viruses are "spreading rapidly" in the lead-up to the holidays, with RSV, flu and COVID-19 continuing to spread as days shorten and temperatures cool.

"Vaccines remain our best tools to prevent the worst outcomes from COVID-19 and flu. I strongly recommend all that have not gotten full protection from COVID-19 and the flu to get vaccinated right away.
