G7 leaders are to commit to using all their resources in an effort to ensure the devastation caused by a pandemic like Covid-19 is never repeated.
On the second day of their summit in Cornwall, they will issue a declaration that sets out a series of measures intended to achieve this.
The aim is to slash the time needed to develop vaccines to under 100 days.
Mr Johnson, who is hosting the three-day gathering at the Cornish seaside resort of Carbis Bay, said it was vital to learn from the “mistakes” of the 2008 financial crisis and tackle the “scar” of inequality.
After Friday’s talks, the leaders were joined the Queen for a dinner at the nearby Eden Project.
As they posed for a group photo, the monarch was heard to joke: “Are you supposed to be looking as if you’re enjoying yourself?”
The leaders around the Queen laughed, and Mr Johnson replied emphatically: “Yes.” The prime minister added: “We have been enjoying ourselves – in spite of appearances.”
The G7 (Group of Seven) is an organisation made up of the world’s seven largest so-called advanced economies: Canada, France, Germany, Japan, Italy, the UK and the US.
Two top EU politicians are also attending the summit.
The G7 leaders will issue the Carbis Bay Declaration after a special session on Saturday, which will set out a plan to try to prevent any repeat of the human and economic devastation wreaked by Covid-19.
Globally, more than 175 million people have had the infection since the outbreak began, with over 3.7 million Covid-related deaths, according to America’s Johns Hopkins university.
The G7 declaration will spell out a series of concrete steps, including:
Slashing the time taken to develop and licence vaccines, treatments and diagnostics for any future disease to under 100 days
Reinforcing global surveillance networks and genomic sequencing capacity
Support for reforming and strengthening the World Health Organization (WHO)
Before the talks, Mr Johnson said: “In the last year the world has developed several effective coronavirus vaccines, licensed and manufactured them at pace and is now getting them into the arms of the people who need them.
“But to truly defeat coronavirus and recover we need to prevent a pandemic like this from ever happening again. That means learning lessons from the last 18 months and doing it differently next time around.”
The declaration is expected to incorporate recommendations from a report by a group of international experts drawn from across industry, government and scientific institutions.
UN Secretary General António Guterres and WHO director Dr Tedros Ghebreyesus will also take part in Saturday’s session.
Dr Tedros stressed that “the world needs a stronger global surveillance system to detect new epidemic and pandemic risks”.BBC
