Vaccinated people are getting breakthrough symptoms from Delta. They're just not dying from it and most aren't ill enough to go to the hospital.

With no immunity to the virus, an infected person will take about 2 weeks to mount an effective immune response, enough time to kill some people who are infected. With immunity, that is cut down to days. We're seeing breakthrough mild infections because the Delta variant tends to hit people so quickly. The rapid immune response just means it won't hit them very hard unless there are massive underlying health conditions and/or a poor immune response.
