DONALD TRUMP says fewer Americans are choosing to get vaccinated against Covid-19 due to mistrust of the Joe Biden administration.
He also claims the public doesn't trust the mainstream media, as well as the results of the 2020 presidential election.
In a statement posted on his 'Save America' website, Trump wrote: "Joe Biden kept talking about how good of a job he's doing on the distribution of the vaccine that was developed by Operation Warp Speed or, quite simply, the Trump Administration.
"He's not doing well at all. He's way behind schedule, and people are refusing to take the vaccine because they don't trust his Administration, they don't trust the Election results, and they certainly don't trust the Fake News, which is refusing to tell the Truth."
Back in April, the US was administering over three million Covid-19 vaccines per day, but that figure has slowed to around 500,000 in recent weeks.
Although Biden narrowly missed his goal of vaccinating 70% of Americans by Independence Day, the nation's vaccination programme has been of the world's fastest.
With that in mind, Trump says he doesn't get enough credit for creating the vaccine, via his vaccine-development programme Operation Warp Speed, which was established in April 2020 to facilitate and accelerate the development, manufacturing, and distribution of Covid vaccines.
The first two vaccines to be developed were created by American-owned companies; Pfizer and Moderna.
Last week, President Biden criticised Facebook for allowing anti-vaccination misinformation to spread on its platform, even going so far as to say they were "killing people" by doing so.
Facebook defended itself against Biden's assertion in a lengthy corporate blog post by Guy Rosen, a company vice president.
In the post, he wrote, "The data shows that 85% of Facebook users in the US have been or want to be vaccinated against COVID-19. Biden's goal was for 70% of Americans to be vaccinated by July 4.
"Facebook is not the reason this goal was missed."
