 And moving away from that, the World Health Organization Director-General Tedos Ghebreuses says the COVID-19 pandemic was far from over and urged equitable access to vaccines during a news conference. Tedos said he believed the right political will and incentives would help to end the pandemic. WHO experts are preparing a proposal on the next studies to be carried out into the origins of the virus that causes COVID-19. There has been broad consensus this week that equitable access to vaccines is essential for ending the COVID-19 pandemic. With over 3.5 million recorded deaths from COVID-19, an estimated loss of the global economy of $22 trillion and new variants compounding explosive outbreaks, this pandemic is far from over. We would, though, like for everyone out there to separate, if they can, the politics of this issue from the science. This whole process is being poisoned by politics. And if you expect scientists to do their work, if you expect scientists to collaborate and actually get the answers that you want, actually seek in a non-blame environment to find the origin of the virus. So we may all learn how to prevent this happening in future. We would ask that this be done in a depoliticized environment where science and health is the objective of this and not blame on politics. In fact, one dose boosts immunity when in people who've had a previous COVID infection. So single dose in people who've been previously infected is as good as getting two doses of the vaccine.
