Donald Trump, President of the United States of America, asserted that the Covid-19 pandemic might 'go away' without a vaccine. He made the comment while being asked about the importance of a vaccine in the fight against the Sars-Cov-2 coronavirus. Trump said that after the virus 'goes away', there might still be some flare-ups, but the authorities would be able to 'put them out'. He added that having a vaccine would be 'very helpful'. There is a global race to develop a vaccine against the virus which has killed over 2.7 lakh people so far.
