Penn State is sending out an anonymous survey to students this week to ask them about their current COVID-19 vaccination status or potential plans to get vaccinated before the fall semester begins.

The university is now surveying students just one week after sending out a similar survey to faculty and staff. Selected students should receive an email with a link to the optional survey that should take about two minutes to complete.

In an email, Penn State President Eric Barron said understanding the student body’s COVID-19 vaccine status will help the university plan for the fall semester.

“We are all looking forward to being reunited on our campuses this fall, and to do so safely, it is important for the university to understand how many of us are vaccinated for COVID-19 to determine what, if any, additional mitigation strategies may need to be implemented this fall,” Barron wrote.

It’s unclear if the university would ever publicize how many students or employees are vaccinated against COVID-19. So far, submitting proof of COVID-19 vaccinations has been only voluntary.

To date, Penn State hasn’t mandated COVID-19 vaccines for students or employees. Instead, it’s focused on incentivizing them through raffles and giveaways, including drawings for $1,000 prizes.
