COVID-19 Vaccine Breakthrough Infections

Vaccine breakthrough cases are expected. COVID-19 vaccines are effective and are a critical tool to bring the pandemic under control. However, no vaccines are 100% effective at preventing illness. There will be a small percentage of people who are fully vaccinated who still get sick, are hospitalized, or die from COVID-19. A recent CDC report highlights what we know to date about breakthrough infections.

  • ¬†As of April 13, 2021, more than 75 million people in the United States had been fully vaccinated against COVID-19 since December 14, 2020.
  • During the same time, CDC received 5,814 reports of vaccine breakthrough infections from 43 U.S. states and territories.
  • Vaccine breakthrough infections were reported among people of all ages eligible for vaccination.
  • 1,695 (29%) of the vaccine breakthrough infections were reported as asymptomatic.
  • 5% people with breakthrough infections were known to be hospitalized and 1% died presumably as a result of their breakthrough infection.

It is important to note that reported vaccine breakthrough cases will represent an undercount, that these surveillance data are a snapshot to help identify patterns to look for signals among breakthrough cases.

Take Home Points

  • Vaccine breakthrough cases occur in only a small percentage of vaccinated persons.
  • COVID-19 vaccines are effective.
  • CDC recommends that fully vaccinated people continue take steps to protect themselves and others in many situations, like wearing a mask, maintaining an appropriate social distance from others, avoiding crowds and poorly ventilated spaces, and washing their hands often

So very rarely vaccinated persons can still get COVID-19. In camp we assume that most, but not all, staff will be vaccinated. This month in LLB Signature sessions, we will discuss four Vaccination Status Scenarios to consider in this setting:

  1. Testing Staff by Vaccination Status
  2. Bubble Poppers by Vaccination Status & Off-Camp Exposures
  3. Days Off by Vaccination Status
  4. Cohorts During by Vaccination Status During Staff Training
