(ANSA) - ROME, SEPTEMBER 04 - "WHO will never approve a vaccine against the coronavirus that is not effective and safe. Vaccines can only be used after verifying that they are effective and safe".
The director general of the UN agency Tedros Adhanom Ghebreyesus said in the usual briefing on Covid-19.
"No-vaxes can build their own narrative, but the vaccine story speaks for itself. Vaccines have changed the world. People can see for themselves, especially parents," he added.
