Episode notes
Omicron's Mutations
- Omicron has many mutations, over 30, on its spike protein.
- This raises concerns about increased transmissibility because the spike protein is how the virus binds to cells.
Travel Ban Ineffectiveness
- Travel bans seem bold but are ineffective for containing the spread.
- They disrupt lives and may penalize countries like South Africa for their transparency in sharing information.
Vaccine Effectiveness
- The effectiveness of current vaccines against Omicron is uncertain, but studies are underway.
- Experts expect some protection, especially with boosters, but Omicron's mutations add complexity.
