To ensure people that the coronavirus vaccine is safe for human use, three former US Presidents Barack Obama, George W. Bush, and Bill Clinton have announced to volunteer themselves to get vaccinated publicly and it will be televised to encourage other Americans to get themselves vaccinated.

Former US President Barack Obama said in an interview with a radio station that "I promise you that I will be taking it when it's been made for people who are less at risk." and as per reports with Obama, former US Presidents George W. Bush and Bill Clinton also said through their spokespersons that they are willing to take a vaccine to urge Americans to do the same.

The three most recent former presidents, Barack Obama, Bill Clinton, and George Bush will be doing so to promote confidence in its safety and effectiveness in an attempt to convince the public to take the vaccine.

The former presidents' comments come as pharmaceutical companies are working to get a viable coronavirus vaccine approved by U.S. regulators before the end of the year.

However, The quick development of vaccines by Pfizer and Moderna has drawn skepticism from members of the public who are concerned about the risks of the shots as well as their effectiveness. Both companies say their vaccines are about 95% effective.
