    Nov 12 (Reuters) - Gold rose on Thursday as market optimism
over a potential COVID-19 vaccine gave way to concerns over the
logistics of its eventual roll-out, though prices were
underpinned by expectations of further monetary stimulus. 
    Spot gold        was up 0.3% at $1,869.52 per ounce by 1323
GMT, while U.S. gold futures        were 0.4% higher at
    "We're starting to see some doubts creeping in about how
quickly any vaccine can be rolled out," said Michael Hewson,
chief market analyst at CMC Markets UK.
    "We may see further stimulus measures kick in as we head
into year-end because, ultimately, the problems of rising
(COVID-19) cases, hospitalizations and deaths are here and now.
And a vaccine is not going to change that." 
    Gold prices are still down about 4.1% so far this week after
Monday's encouraging late-stage vaccine trial data from Pfizer
Inc         powered a surge in equities and drove a sharp
retreat in safe-haven bullion. 
    European Central Bank President Christine Lagarde signalled
further economic support on Wednesday, with infections expected
to spike as winter sets in.                          
    Gold has risen about 23% this year amid unprecedented global
stimulus during the pandemic, given its status as a hedge
against likely inflation and currency debasement resulting from
the measures.
    "The intensifying second coronavirus wave is likely to delay
the economic recovery process, raising the level of uncertainty
and supporting the precious metal," said Hitesh Jain, lead
analyst at Mumbai-based Yes Securities. 
    Investors are now awaiting weekly U.S. jobless claims data
due at 1330 GMT, which could provide further insight on the
health of the world's largest economy.
