As I had cautioned in some of my earlier posts:
https://www.cnbc.com/2021/01/21/dr-...-less-effective-against-some-new-strains.html
Fauci is now also of the view that we may have to tweak the vaccines for the new variants. The speed with which the virus has spread means that it has plenty of hosts to experiment with and bring out a natural alpha strain. The precautions are more necessary than ever to limit the mutations.
It also presents another marker towards my timeline:
- North America/Europe to finish their first vaccinations by fall 2021
- The broader world to go through its first vaccination on a rolling basis by 2022
- North America/Europe to complete their tweaked vaccines by 2022
- The broader world to do so by 2023
- General travel precautions largely relaxed by 2023
- Cruise travel precautions largely relaxed after the 2023-24 flu season
What worries me now - my pessimistic case - is the vaccination take-up in North America and Europe. If it becomes clear that the current vaccines are not going to as effective against the new strains, a lot more people might end up sitting out the first round. And that would be a tragedy.
