Sen. Rand Paul, R-Ky., said Sunday he is not getting vaccinated because he already had Covid-19.

Speaking with a conservative radio host on WABC radio, Paul, an Ophthalmologist, said he won’t change his mind unless he sees evidence that people who have already been infected are again getting very sick, needing hospitalization or dying.

“Until they show me evidence that people who have already had the infection are dying in large numbers, or being hospitalized or getting very sick, I just made my own personal decision that I’m not getting vaccinated because I’ve already had the disease and I have natural immunity,” Paul said.

The Centers for Disease Control and Prevention recommends that those who have been previously infected get vaccinated because experts are not certain of how long natural immunity lasts.

Paul was the first known senator to contract the virus when he tested positive in March 2020.
