Former US presidents Barack Obama, George W. Bush and Bill Clinton said that they were willing to be vaccinated in public to promote public confidence
The World Health Organisation has warned that vaccines will be no magic bullet for the coronavirus crisis as nations gear up for a massive rollout to tackle surging infections.
The word of caution comes as the United States clocked a record number of Covid-19 cases for a second day in a row, with the country preparing for what US President-elect Joe Biden has called a "dark winter"
Meanwhile, a growing number of leaders are saying they plan to be vaccinated in public to build trust.
US president-elect Joe Biden said Thursday he was willing to be vaccinated in public -- following up on similar commitments from former US presidents Barack Obama, George W. Bush and Bill Clinton.
WHO director-general Tedros Adhanom Ghebreyesus said on Friday he was also willing to be filmed getting vaccinated to promote public confidence.
Anti-vaccine sentiment has been rising in recent years, which could hamper efforts to reach a sufficient number of people to force down the spread of the virus.
