Professor Chris Whitty will be making an announcement on Downing Street today.
The Chief Medical Officer for England will lead the address and will be accompanied by Health Ministers from the four nations.
Boris Johnson will not be there. The Prime Minister will give a separate speech tomorrow on the government’s Covid winter plan.
Professor Whitty’s announcement comes after the UK’s four Chief Medical Officers (CMOs) said that children between the ages of 12 and 15 should be offered a first dose of the Pfizer / BioNTech vaccine.
The schools are expected to get vaccinations as soon as possible.
In their advice to the government, the UK CMOs said they would recommend vaccines for “public health reasons” and that it was “likely that vaccination will help reduce the transmission of Covid-19 in schools”.
They added, “Covid-19 is a disease that can be transmitted very effectively through mass spreading events, especially with the Delta variant.
“Having a significant proportion of students vaccinated is likely to reduce the likelihood of events likely to lead to local outbreaks in or associated with schools.
“They will also reduce the likelihood that a single child will get Covid-19. This means that vaccination will likely reduce (but not eliminate) educational disabilities. “
