Kloots shared her husband’s long battle with the coronavirus before dying in July at the age of 41.
She said on Friday in an Instagram post that she was grateful to have been vaccinated against the virus that left her alone.
“I’ve been terrified since Nick has gone, as a single mother, from having this virus and now I’m one step closer to safety,” she wrote.
Some were criticized for receiving the vaccine because he was 38, but he explained that he waited in a long line and only got the leftover doses of vaccine that would have expired after meeting all appointments for the day.
He said anyone else could have done the same and should not be “ashamed of the vaccine.” She believes anyone who gets the vaccine should be celebrated.
In response to his criticism, he said staff were “happy to have people there waiting with weapons ready” and that they were willing to be sidelined, ABC News reports.
Kloots and Cordero shared a 1-year-old son named Elvis, who Kloots said was with her when she received the vaccine while Cordero’s song was being played in the car.
On Sunday, the United States was on the verge of achieving 500,000 COVID-related deaths.
