I am annoyed at Fauci for the second time, this time for dissing the AZ vaccine:

But even if the vaccine ends up being approved, it will probably only have an efficacy of 60 to 70 percent. “What are you going to do with the 70 percent when you’ve got two (vaccines) that are 95 percent? Who are you going to give a vaccine like that to?” Anthony Fauci, the leading American expert on vaccines, recently wondered.

This attitude is counter-productive. As I wrote earlier:

In the big picture, the efficacious of a vaccine doesn’t matter per se what matters is getting to herd immunity. If you have a less efficacious vaccine you need to vaccinate more people but herd immunity is herd immunity, i.e. vaccines mostly protect people not because they are efficacious but because we reach herd immunity.

As a result, it can be much better to start vaccinating now with a 70% efficacious vaccine than wait for a 95% efficacious vaccine–thus, we need to encourage early vaccination. Indeed the AZ vaccine ought to be approved immediately (I predict the UK will approve by next week) and be made available to anyone who doesn’t want to wait for another vaccine.

For the next year or two, we will be operating under conditions of scarcity and we need to use every tool at our disposal. A 70% effective vaccine is great, well above what the FDA required and better than the flu vaccine. If you live in a country in which everyone has been vaccinated you won’t give a damn whether they were vaccinated with a 95% effective vaccine or a 70% effective vaccine–both will give you nearly 100% safety and allow life to return to normal.
