British Prime Minister Boris Johnson has revealed that 2.4 million people have been vaccinated against the novel coronavirus across the UK.
Speaking Monday during a visit to a newly-built mass COVID-19 vaccination center in Bristol, he added some 40 percent of senior citizens over the age of 80 as well as a quarter of care home residents have been inoculated so far.
Nevertheless, Johnson urged the public to maintain maximum vigilance.
"It's still the case, as I as I talk to you today, that the UK has done more vaccinations than any other country in Europe, but we cannot be complacent and the worst thing now would be for us to allow success in rolling out the vaccine program to breed any kind of complacency about the state of the pandemic."
The UK government's goal is to vaccinate 15 million people by mid-February, targeting people over 70, front line healthcare workers and others especially vulnerable to the virus, a task Johnson described as achievable.
Elsewhere, Russia says roughly 1.5 million people have received its Sputnik V COVID-19 vaccine globally.
The Russian Direct Investment Fund, which financed development of the vaccine, explained the shots have not caused any severe allergic reactions.
It also added that Palestine has become the first Middle Eastern country to approve the Sputnik V vaccine.
Despite the mass inoculation plans in many parts of the world, the WHO's top scientist said herd immunity against COVID-19 will not be achieved this year.
The global health body highlighted that until then, virus prevention measures, including social distancing and wearing face masks, will be crucial.
