Is Trump Immune to the Coronavirus? Maybe, Maybe Not Steve Baragona On the same day President Donald Trump suggested he is protected from the coronavirus after his bout with COVID-19, researchers showed that a person can be infected with the virus twice. "I went through it. Now they say I'm immune," Trump said at a campaign rally in Florida Monday. "I feel so powerful." But in a new study, scientists detail the case of a Nevada man who tested positive for coronavirus, recovered, and contracted the virus again weeks later. The evidence not only raises questions about how long immunity lasts after infection, but it also raises the possibility that a vaccine will not provide permanent protection. "It is totally irresponsible for the president to go around claiming that he's immune," said Andrew Pavia, chief of the pediatric infectious diseases division at the University of Utah, who was not part of the new study. "That's just not something that we can say with any scientific certainty." .
