Three Vaccine Challenges: Infection Blocking, Variants, and Durability

We also need to fix the three problems of vaccines.

The current vaccines are not infection blocking.

They're not broad. So when new variants come up, you lose protection.

And they have very short duration,

particularly in the people who matter, which are old people.

And every one of those things is fixable.

In fact, doing that work

is going to help vaccinology very, very broadly.
