LONDON, Dec 2 (Reuters) - British Prime Minister Boris
Johnson cautioned people in Britain on Wednesday not to get
their hopes up too soon about the swift roll out of the
Pfizer-BioNTech vaccine, saying there were logistical challenges
to overcome.
"I think at this stage it is very, very important that
people do not get their hopes up too soon about the speed with
which we will be able to roll out this vaccine," Johnson told
parliament.
"We are expecting several million doses of the
Pfizer-BioNTech vaccine before the end of the year. We will then
be rolling it out as fast as we possibly can."
