X-rays have revealed the stark difference between the lungs of those who have had the Covid vaccine and those who have not.
The scans show the shocking impact Covid has on people's internal organs with doctors saying unvaccinated people are the ones "getting really sick".
Dr Sam Durrani, the chief of staff at Deer Valley Medical Center, said: "The only people that are really getting sick are people that are unvaccinated.
"[They] oftentimes require ventilation and oxygen, especially on some of these really profound X-rays that we are seeing."
Vaccinated patients who are infected with Covid have more air flowing to their lungs, with the larger part of the lungs coloured in black on the scans, Dr Durrani explained.
This means there is very little or no damage to the lungs.
The image of a scan from an unvaccinated person shows that the lungs are very congested, limiting the oxygen flow throughout the entire body.
Dr Durrani said: "If you have a vaccinated patient that comes to the ER with a breakthrough infection, that maybe have some shortness of breath and we do a CT scan, they’re not nearly as bad as the unvaccinated patients.
"Even the breakthrough infections that end up getting pneumonia, their CT scans still were not as bad as the ones of unvaccinated patients."
Vaccines have been successful in preventing severe illness and death in most people who catch Covid, but it will not work for some.
Some double-jabbed people will still end up in hospital with Covid but with a much lower level of congested lungs compared to those without any vaccine protection.
Data from the US Centers for Disease Control and Prevention (CDC) shows that risk of dying from Covid is 11 times higher for unvaccinated adults than those who have been inoculated.
In England, just one per cent of all Covid deaths are in those who have been fully vaccinated.
"The vaccine is working extremely well and is keeping the virus from progressing to pneumonia or infiltrating the lungs," Dr Durrani said.
"When you get a dose you can get a little sick, but eventually your body recognises it, it attacks it and you don’t get hospitalised, you don’t get put on a ventilator, it’s very profoundly effective."
