Three former US presidents have offered themselves for the corona vaccine to allay public concerns.
The corona virus has killed millions of people around the world, but now the good news is that the vaccine is coming.
Two US companies have claimed to have developed the vaccine and have asked the government for permission to use it on a large scale.
The US Food and Drug Administration (FDA) is considering the requests and hopes to approve them soon.
The problem, however, is that there are large numbers of people around the world who view Corona with suspicion and are reluctant to vaccinate themselves. Conspiracy theories are the biggest reason for this.
