Former President Donald Trump claimed the world could have seen 100 million deaths from COVID-19 if his administration hadn't developed the vaccine.

'I think if we didn't come up during the Trump administration with the vaccine, you could have 100 million people dead just like you had in 1917,' Trump said Saturday night during an interview with Fox News' Dan Bongino.

Trump, who was discussing the reopening of schools, says he is very proud of the vaccine and that it 'has been great for the world'. 

He claims without it America would've seen fatalities similar to those from the Spanish flu - which is believed to have killed 40million to 100million worldwide. Around 675,000 were killed in the United States.

The former president also said he hopes that educators will get the vaccine so that schools can reopen.

'The schools have to open,' he said. 'These young people are losing a big part of their life and they're not going to recover from it.' 

Trump argued that school closures are leaving a 'psychological scar' on children, citing the impact of students' lack of social interaction.

'We have to open our schools. I say, let the teachers get the vaccine — they should get the vaccine, I hope they do,' Trump continued, saying that some teachers don't 'ever want to go back to work' due to virus concerns.

While Trump said he supports the vaccine, he also reiterated that he is against pandemic mandates.
