  Pfizer COVID-19 vaccine reduces transmission after one dose -UK study
  LONDON, Feb 26 - A single dose of Pfizer and BioNtech’s COVID-19 vaccine cuts the number of asymptomatic infections and could significantly reduce the risk of transmission of the virus, results of a UK study found on Friday.Researchers analysed results from thousands of COVID-19 tests carried out each week as part of hospital screenings of healthcare staff in Cambridge, eastern England.“Our findings show a dramatic reduction in the rate of positive screening tests among asymptomatic healthcare

Those purchases are intended to keep longer-term rates low to encourage borrowing and spending.</p>\n<p>But the Fed’s policymaking committee appears likely to start discussing the timing and mechanics of gradually reducing its bond purchases.

Such price increases may not last.</p>\n<p>“I think they still feel pretty strongly that what we’re seeing is transitory,” said Steve Friedman, an economist at investment firm Mackay Shields and a former senior staffer at the New York Federal Reserve Bank.</p>\n<p>Another key consideration is whether inflation persists long enough to affect the public’s behavior.

Another is whether they should reduce their purchases of Treasury and mortgage bonds at the same pace.
