Episode notes
BSL-3 Lab Protective Gear
- Scientists at the Texas Biomedical Research Institute wear multiple layers of protective gear to handle deadly viruses in a BSL-3 lab.
- The rigorous biosecurity measures resemble beekeepers' suits to prevent any contamination or infection.
Reverse Genetics in Vaccine Creation
- Labs use reverse genetics to create recombinant influenza viruses for research and vaccine development.
- These lab-made vaccine seed viruses don't infect humans but trigger antibody responses.
Eggs Are Essential for Vaccines
- Millions of fertilized eggs are used yearly to grow flu viruses because they thrive in the allantoic fluid inside eggs.
- This method is crucial for producing vaccine seed viruses for flu shots at scale.
