The World Health Organization says it expects a coronavirus vaccine will be available equitably no earlier than the middle of 2021.
On Friday, chief scientist Soumya Swaminathan said it would be distributed under an international framework being funded by Japan, Britain and 76 other countries.
Swaminathan said candidate vaccines are being tested in multiple countries, with some already in Phase 3 clinical trials. She said results are expected by the end of the year, or the beginning of 2021.
Bruce Aylward, Assistant Director-General of the WHO, said there are some things that can be sped up, but others that can’t due to the need to confirm safety and efficacy.
Some countries are working to have vaccinations available before a global rollout.
