While we wait for the UK prime minister's press conference to start, we have some news from Nigeria where health officials say they are worried that fake coronavirus vaccines are being sold in the country.
Nigeria's National Agency for Food Drug and Administration Control "is pleading with the public to beware".
"Fake vaccines can cause Covid-like illnesses or other serious diseases that could kill," warned Mojisola Adeyeye, the agency's director general.
Black market coronavirus tests also reportedly appeared in April.
There has been a sharp rise in infections in Nigeria in recent weeks, and the vaccine rollout is not expected to begin until March.
Nigeria, which has a population of 201 million, has 10 million doses due to arrive in March, but it hasn't been specified which type of jab would be used.
A total of 100,000 doses of the Pfizer-BioNTech vaccine have already been confirmed.
