Kloots shared her husband’s long battle with coronavirus before he died in July, at the age of 41.
She said in an Instagram post on Friday that she was grateful she had been vaccinated against the virus that left her a single mother.
“I’ve been horrified since Nick went through this virus as a single mother, and now I’m one step closer to safety,” she wrote.
She was criticized by some for receiving the vaccine because she is 38 years old, but explained that she waited in a long line and received only the remaining doses of the vaccine that would have expired after all the meetings were completed for respectively.
She said that anyone else could have done the same and that “vaccine shame” should not happen. She believes that anyone who receives the vaccine should be celebrated.
In a response to her critics, she said the staff was “happy to have people there waiting with well-disposed weapons” and was ready to be removed, ABC News reports.
Kloots and Cordero shared a 1-year-old son named Elvis, whom Kloots said was with her when she received the vaccine, while Cordero’s song was played in the car.
On Sunday, the United States was on the verge of hitting 500,000 COVID-related deaths.
