COVID-19 Q&A: Some COVID-19 infections in vaccinated people are expected

What is a vaccination breakthrough case of COVID-19?

A COVID-19 vaccination breakthrough case is when someone who is fully vaccinated tests positive for COVID-19 more than 14 days after getting the second dose of Moderna or Pfizer vaccines, or more than 14 days after getting the Johnson & Johnson vaccine.

Are breakthrough cases common?

Breakthrough cases are expected, but they are not common. No vaccine is 100 percent effective at preventing illness, and that includes the COVID-19 vaccines.

Let’s do some math.

In Idaho, 826,587 people were fully vaccinated as of Oct 27. Of those, 13,285 had experienced a breakthrough case. That means 1.6 percent of fully vaccinated people have experienced a breakthrough case. Or 98.4 percent of fully vaccinated people haven’t experienced a breakthrough case.

The Department of Health and Welfare tracks breakthrough cases in Idaho on its COVID-19 data dashboard at the bottom of the Case Characteristics page.

Do breakthrough cases mean the COVID-19 vaccines don’t work?

The vaccines are working. They are especially effective against hospitalization and death, and they greatly reduce your chances of getting COVID-19 in the first place. If you do have a breakthrough case, it further reduces the likelihood that you will be sick enough to have to go to the hospital or die.

Are people contagious who have a vaccination breakthrough COVID-19 infection?

They can be. That’s why it’s important to do several things to help prevent the spread of disease, including getting vaccinated and wearing a mask indoors and in crowded places outdoors.

Department of Health and Welfare Director Dave Jeppesen also wrote about breakthrough cases in his blog on Oct. 29.
