SAN DIEGO (KGTV) – Side-by-side x-rays of COVID-19 positive lungs illustrate the impact vaccines can have.
University of California San Diego radiologist Dr. Albert Hsiao has been interpreting x-rays of COVID patients since the start of the pandemic.
In one image, the lungs of the vaccinated person reveal a lot of black space, which means it is filled with air. In another image, the lung of the unvaccinated person is much cloudier, which means the infection has taken over.
“The cloudy white areas that you see, the areas of the lungs filled with fluid or immune cells, or the virus itself,” Dr. Hsiao said.
In contrast, Dr Hsiao says the lighter x-ray shows the vaccine in action. He recognizes the virus as a foreign invader and then fights it.
“The vaccine prevents the virus from replicating as quickly, as freely in a vaccinated person as in an unvaccinated person. This gives the immune system a head start before the virus gets out of hand, ”said Dr Hsiao.
Another set of side-by-side images are from the lungs of the same patients. An AI algorithm identified and colored the areas of infection. In the pictures, the lungs of the unvaccinated person are filled with colors.
This patient remains hospitalized. The vaccinated patient was sent home.
“These x-rays illustrate how amazing and effective vaccines are in protecting us from this virus,” said Dr Hsiao.
It is not known if either patient’s virus has been sequenced, but it is likely that both are cases of the Delta variant.
