Breakthrough cases will become more common as the more transmissible Delta variant keeps spreading.
But most disease experts still expect COVID-19 to be milder in vaccinated people.

Breakthrough infections, or COVID-19 cases diagnosed after someone is fully immunized, were supposed to be rare – at least that’s what a report from the Centers for Disease Control and Prevention suggested in May. At the time, data indicated that just 0.01% of vaccinated Americans got a breakthrough case from January to April.
But that was before the more transmissible Delta variant became the dominant strain in the US.
The share of breakthrough infections also inevitably rises as more people get vaccinated – though it’s hard to know how many of these cases occurred since the CDC report came out. The agency stopped tracking asymptomatic, mild, or moderate breakthrough cases on May 1.
Though the current vaccines still protect against Delta, the chances that you’ll know someone with a breakthrough case, or develop one yourself, are higher than they’ve ever been.
But most disease experts still expect COVID-19 to be milder in vaccinated people, regardless of the variant.
“The variants may cause you to still maybe get an infection, but not serious,” Peter Gulick, an associate professor of medicine at Michigan State University, told Insider in June. “It would be almost like getting an infection with the common cold or one of those nagging things that gives you sniffles and a cough and makes you feel a little tired, but nothing serious enough to put you in the hospital or put you on a ventilator.”
Indeed, the COVID Symptom Study – a project that tracks self-reported COVID-19 symptoms via an app – suggests that a headache and runny nose are two leading indicators of a COVID-19 infection among vaccinated people in the UK, followed by sneezing, sore throat, and loss of smell. Vaccinated people in the study also reported fewer overall symptoms over a shorter period of time than those who hadn’t received a shot.
Insider spoke with two young people who recently recovered from mild breakthrough infections to see how their symptoms progressed.

Sam Reider, a musician who lives in San Francisco, was fully vaccinated with Pfizer’s shot in mid-April. (New research suggests that Pfizer’s two-dose vaccine is 88% effective against symptomatic COVID-19 from Delta – down from 95% against the original strain.)
In mid-June, Reider taught a music camp a few hours outside the city. Of the roughly 50 people in attendance, he said, most were older children who had been vaccinated. A handful of unvaccinated kids under 12 wore masks.
But Reider got sick anyway. His first symptoms – exhaustion and a headache – resembled “that feeling of being super jet-lagged after an international flight,” he said. Soon after, …read more
