Khloé Kardashian Is Protective of 3-Year-Old True's Self-Image After 'How People Critiqued My Body' "It was so incredibly scary," Kardashian told host Ellen DeGeneres last October about her bout with the coronavirus. "I mean, it still is scary, but especially then when the whole world was shutting down and we didn't have really any information or the information we had changed every single day."

We had to wait until I had negative test results for me to leave, and that was the hardest part," the mom of one recalled. "I mean, I don't care how beautiful of a place you have, being taken away from your child for that long, because I couldn't be around my daughter, that was the most heart-wrenching thing." Kardashian clarified that she has been vaccinated against COVID-19, meaning she contracted a breakthrough case. Breakthrough cases — COVID-19 infections that occur in people who have been fully vaccinated against the virus — are possible and expected, as the vaccines are not 100% effective in preventing infections. Still, vaccinated people who test positive will likely be asymptomatic or experience a far milder illness than if they were not vaccinated. The majority of deaths from COVID-19 — around 98 to 99% — are in unvaccinated people.
