The first phase of testing used a vaccine with known antigens designed for melanoma.

The Community Health Station program was initially established to continue the distribution of COVID-19 antigen tests, also known as rapid tests, according to the public health department.

“We don’t have the ability to differentiate through quick, antigen tests at this time,” Katelyn Jetelina, an epidemiologist and author of the newsletter Your Local Epidemiologist, told Salon.

One avenue for this ambition is cell receptors, which function like ignition slots on a cell, requiring keys -- such as specific hormones, drugs, or antigens -- to start up specific cellular activities.

All cancers -- particularly immune-silent, fast-growing cancers like glioblastoma -- produce signals called antigens that scientists can use in immune therapies to manually alert the immune system to the presence of incognito cancers.
