Stanford University reported at least seven confirmed cases of COVID-19 among fully vaccinated students this week.
All seven students were symptomatic, according to the school.
“As you have seen in the national news, cases of COVID-19 have been ticking upward,” Stanford University officials said in a letter to students on Thursday. “We are seeing some of this in our own community, where we are experiencing an increase in the number of student COVID cases, including among fully vaccinated individuals.”
Although the chances of contracting the novel coronavirus after being fully vaccinated are very rare, so-called breakthrough cases are still possible. Although COVID-19 vaccines have shown to be highly effective, they do not block the virus 100% of the time, meaning that some breakthrough infections occur after vaccination. This is normal and expected, and it’s not proof that the vaccines aren’t working, experts said.
