The Oscar-winning actor, 63, revealed last week that he and his wife, singer Rita Wilson, have volunteered to give their blood and plasma to COVID-19 research.

“We have not only been approached, we have said, ‘Do you want our blood? Can we give plasma?’ And, in fact, we will be giving it now to the places that hope to work on what I would like to call the Hank-ccine,” Hanks said on NPR’s podcast “Wait Wait…Don’t Tell Me!”

Hanks said the couple recently learned that they had antibodies from their battle with the dangerous bug last month in Australia.

“A lot of the questions [are] what do we do now? Is there something we can do? And, in fact, we just found out that we do carry the antibodies,” Hanks said.

The actor said in another interview last week that the couple still doesn’t know how they contracted coronavirus while down under, where he was filming Baz Luhrmann’s forthcoming Elvis Presley biopic.
