According to the Centers for Disease Control and Prevention (CDC), common side effects of the COVID-19 vaccine include tiredness, fever, and chills. However, a new poll has revealed a side effect of not getting the vaccine: losing friendships.

MyBioSource.com, a biological reagent provider, reports that 44% of fully vaccinated Coloradans will avoid friends and colleagues who haven't gotten the vaccine. While this may seem harsh, we are under the national average, which is 48%.

Whether you think those Coloradans are being judgemental or cautious, some pushed it even further — 40% of those surveyed said they were prepared to pause or end friendships with people who refused to get the vaccine.

Maryland is particularly stringent when it comes to COVID-19 vaccines, with 65% of residents stating that no vaccine is a friendship dealbreaker. On the other hand, only 11% of Idaho residents plan to avoid unvaccinated friends.

Others hope to take it further than personal avoidance. 46% of those surveyed want businesses to have separate hours for vaccinated populations, while 37% think there should be vaccinated and unvaccinated sections on public transport.

40% of those surveyed also thought positively of "vaccine freebies" — like Colorado's Comeback Cash initiative.

Local officials are currently urging Coloradans to get their vaccines as the delta variant continues to spread across the state, leading to concerns about the return of the mask mandate.

"This highly contagious variant is particularly concerning for vulnerable unvaccinated groups, including those 11 years old and under who can not yet get vaccinated," said Tom Gonzalez, Director of the Larimer County Department of Health and Environment (LCDHE), in a statement. "Getting vaccinated now can significantly improve protection for yourself and for our community."

The Poudre School District (PSD) is debating reimplementing the mandate; however, the Greeley-Evans School District has decided to keep masks optional for the upcoming school year.
