WASHINGTON, April 27 (Reuters) - The White House is considering options for maximizing production and supply of COVID-19 vaccines for the world at the lowest cost, including backing a proposed waiver of intellectual property rights, but no decision has been made, press secretary Jen Psaki said on Tuesday.

"There are a lot of different ways to do that. Right now, that's one of the ways, but we have to assess what makes the most sense," Psaki said, adding that U.S. officials were also looking at whether it would be more effective to boost manufacturing in the United States.
