Virginia Lt. Gov.-elect Winsome Sears once again balked at disclosing her COVID-19 vaccination status when asked in an interview Sunday, this time warning it will lead to wanting to examine her DNA.

Sears, who will serve alongside Republican Gov.-elect Glenn Youngkin after becoming the first woman and first woman of color elected lieutenant governor of Virginia earlier this month, called such a question a slippery slope.

The minute that I start telling you about my vaccine status, were going to be down the bottom of the mountain trying to figure out how we got there, because now youll want to know whats in my DNA, the Republican told CNN s Dana Bash on State of the Union.

Sears, who served as a state delegate in Virginia, has previously refused to disclose her vaccination status when interviewed by CNN, insisting that its a private matter. She has referred to the news network as liberal hack reporters on Twitter , though she has also encouraged others to get the coronavirus vaccine.

If were not careful, were going to start asking for other things, because we have already determined that this is everybodys business, she told CNN last month .

Youngkin has said he is vaccinated against COVID-19 and has also encouraged others to get the vaccine, though he has said he is opposed to vaccine mandates.

COVID-19 cases have been rising across much of the U.S. over the past couple of weeks after a near two-month drop from the summers surge. Virginia is among the states that have seen a high rate of transmission. As of Friday, there have been 953,460 cases of COVID-19 in Virginia and 14,492 related deaths, according to the states Department of Health .
