About 30% of the new COVID-19 cases in Los Angeles are breakthrough cases among the fully vaccinated, Deadline reports.

  • This is an increase from back in March 2021, when breakthrough cases represented only 2% of Los Angeles’ monthly total, according to Deadline.
  • The numbers have been increasing since then. Fully vaccinated breakthrough cases represented 20% of all cases in Los Angeles in June.

Rise in breakthrough cases in LA County

Los Angeles Director of Public Health Barbara Ferrer said Thursday that the number of fully vaccinated Americans who are being infected and hospitalized has been rising throughout the last three months, though the number remains low, according to KTLA.

  • Getting vaccinated remains the main way to stall COVID-19 infections.

Fully vaccinated people represent a small number of those testing positive for COVID-19, according to Deadline. Specifically, 27,331 out of 5.15 million fully vaccinated residents in Los Angeles County have tested positive for COVID-19 — or about 0.53%.

Should you expect COVID breakthrough cases?

Breakthrough cases should be expected. Dr. Rochelle Walensky, the director of the U.S. Centers for Disease Control and Prevention, told CNN that breakthrough cases will happen because the vaccine isn’t 100% effective.

  • “I think we all have to recognize that with 164 million people who are vaccinated, we should expect tens of thousands, perhaps, of breakthrough infections,” she said.
  • “Those breakthrough infections have mild illness. They are staying out of the hospital. They are not dying, and I think that that’s the most important thing to understand,” Walensky told CNN.
