Mayo Clinic Q&A: 'The COVID-19 delta variant has changed everything'

[left-of-center2012]

Where did this delta variant come from? It came from unvaccinated people getting infected in large numbers allowing the virus to continue mutating," says Dr. Gregory Poland, an infectious diseases expert and head of Mayo Clinic's Vaccine Research Group. In the past,
a person with COVID-19 might infect two to four people.
But with the delta variant, one person can infect nine people, according to Dr. Poland.

In this Mayo Clinic Q&A podcast, Dr. Poland answers questions about a person's waning immunity and the likelihood of COVID-19 booster shots. He also explains the two phases of immunity and goes into detail about the extensive Federal Drug Administration license approval process for COVID-19 vaccines.

To practice safe social distancing during the COVID-19 pandemic, this interview was conducted using video conferencing. The sound and video quality are representative of the technology used. For the safety of its patients, staff and visitors, Mayo Clinic has strict masking policies in place. Anyone shown without a mask was recorded prior to COVID-19 or recorded in an area not designated for patient care, where social distancing and other safety protocols were followed.
