From the CDC:


People infected with the Delta variant, including fully vaccinated people with symptomatic breakthrough infections, can transmit the virus to others. CDC is continuing to assess data on whether fully vaccinated people with asymptomatic breakthrough infections can transmit the virus.

So what percentage of covid cases recently, during delta surge, arer among the fully vaccinated.

CDC study in Los Angeles

The new data released on Tuesday involved more than 43,000 reported infections among Los Angeles County residents aged 16 and older. Of them, 10,895, or 25.3%, occurred in fully vaccinated persons, 1,431, or 3.3%, were in partially vaccinated persons, and 30,801, or 71.4%, were in unvaccinated individuals.

Los Angeles Director of Public Health Barbara Ferrer:

Breakthrough Infections Are Now 30% Of All New Covid Cases Amid Delta Surge

In Los Angeles, Breakthrough Infections Are Now 30% Of All New Covid Cases Amid Delta Surge

Your first quote seems pretty clear: symptomatic infections can transmit the virus but it is still undetermined whether asymptomatic breakthrough cases are contagious.

Then the Los Angeles data. LA claims to be 68% fully vaccinated meaning more than twice as many are vaccinated than are unvaccinated. Still, nearly three times as many cases are from the unvaccinated. Twice the number of people generating only one third the total cases makes a good argument that the vaccinated are MUCH LESS likely to become infected.

Much less likely to become infected when vaccinated and undetermined whether vaccinated asymptomatic cases are contagious at all sounds like good news for the vaccines.
