Hitting "herd immunity" is becoming an ever more elusive goal in LA County.
Officials were initially hoping to get 80% of eligible residents vaccinated by the end of June.
But amid falling demand for shots, the goal was pushed back to mid to late-July.
Now, Public Health Director Barbara Ferrer says "I don't know with certainty how long it will take us to get to 75-80 percent of eligible people being fully vaccinated here in LA County. I do know that every person that gets vaccinated gets us closer to that goal."
More than 9 million doses have been administered in the county but fewer than half of residents have been fully vaccinated.
