Close to 7 million vaccine doses have been administered in LA County but we're still far from reaching herd immunity.
It's unclear what percentage of the population needs to be immune to make spread unlikely.
Public Health Director Barbara Ferrer says "We're using 80% of people who are eligible to be vaccinated will need to get vaccinated for us to get herd immunity."
It's estimated there are more than 8.3 million people in the county who are 16 and older.
Eighty percent is close to 6.7 million.
The number of fully vaccinated people in the county isn't even half that.
And there are signs that demand for shots is waning.
Ferrer says "many" sites are not filling appointments as quickly as they used to.
"For those of you who feel scared of getting vaccinated, because of the very small chance of a serious side effect, think about the other things that we do where you also have a small chance of a bad outcome," she says.
Ferrer says you probably wouldn't skip an all-expenses paid vacation because of the tiny risk of dying in a car accident on the way.
Likewise, with vaccinations, the payoff is worth the tiny risk to get us back to normal.
