LONDON: The world’s wealthiest nations, collectively known as G20 nations, must help plug a $4.5 billion funding gap for a World Health Organization-led program to distribute coronavirus vaccines and pave the way for an end to the pandemic, a letter seen by Agence France-Presse (AFP) on Friday said.

The letter, sent ahead of this weekend’s virtual G20 summit, was signed by Norwegian Prime Minister Erna Solberg, South African President Cyril Ramaphosa, WHO chief Tedros Adhanom Ghebreyesus and European Commission president Ursula von der Leyen.
