(Reuters) - Federal Reserve Chair Jerome Powell said on Wednesday that he has been vaccinated once against the coronavirus. Powell, 67, has received the first dose of the COVID-19 vaccine, he told reporters during a news conference after the end of the U.S. central bank’s latest two-day policy meeting. The Fed’s policy-setting committee voted to leave the central bank’s key overnight interest rate near zero and to keep purchasing $120 billion in bonds each month to support the economy.
