We are praying for the speedy recovery of comedian and actor Chris Rock, who confirmed to his fans Sunday that he has tested positive for COVID-19.

Rock shared news his diagnosis via Twitter, and is encouraging others to get vaccinated.

“Hey guys I just found out I have COVID, trust me you don’t want this. Get vaccinated,” Rock posted.

Rock is fully vaccinated, and is considered one of the “breakthrough cases” health experts are advising about.

They say, even though a fully vaccinated person can still catch virus, the immunizations protect them more against hospitalizations and death.

A study published earlier this month by the US Centers for Disease Control and Prevention shows that people who are not vaccinated against COVID-19 were 11 times more likely to die of the disease and 10 times more likely to be hospitalized with the disease.

Rock said during a television appearance on the “Tonight Show” with Jimmy Fallon earlier this year that he received the Johsnon & Johnson vaccine.
