Twitter disabled sharing options on the tweet from Trump on Sunday.

 

Trump said in the tweet: "A total and complete sign off from White House Doctors yesterday. That means I can't get it (immune) and can't give it. Very nice to know!!"

 

If his followers attempted to share the tweet, a pop-up Twitter alert said: "We try to prevent a Tweet like this that otherwise breaks the Twitter Rules from reaching more people".

 

This is not the first time Twitter disabled sharing on a controversial tweet by Trump. The platform has labeled several of Trump's tweets for violating its policy.

 

"It seems like I'm immune, so I can go way out of a basement," Trump also said in an interview on Fox News.

 

"It looks like I'm immune for, I don't know, maybe a long time, maybe a short time. It could be a lifetime. Nobody really knows".

 

White House physician Sean Conley said on Saturday that the president, who tested positive for Covid-19 on October 1 and was later hospitalized for three days before returning to the White House with continued treatment, is "no longer considered a transmission risk to others."

 

However, Conley did not disclose when Trump last had a negative test result.

 

A study published in September in the journal Nature Medicine, however, indicated that recovery from the coronavirus does not confer lifetime immunity.
