Some unvaccinated people have taken to social media to call themselves “purebloods," a reference from  “Harry Potter” that refers to a pure bloodline, which is not mixed with non-wizards.

The “pureblood” trend for the unvaccinated has made its way to TikTok with the hashtag #pureblood.

In a series of videos, these unvaccinated social media users are asking that they no longer be called unvaccinated but instead “purebloods” as they don’t have the COVID vaccine in their bloodlines.

In J.K. Rowling’s “Harry Potter” book series, a “pureblood” has a family bloodline that only has wizards or rather, no muggles - humans without powers.

In the "Harry Potter" books, it was seen as superior to be a “pureblood” and a higher social rank compared to those that were mixed with the so-called muggles.

On TikTok, users are calling for the new “pureblood” title.

One user on TikTok posted in their video, “I will no longer be referred to as Unvaccinated. You can call me a Pureblood.”

Another on TikTok urged others to do the same: “I want everyone now to call me a pureblood.”

The majority of the TikTok videos are set to Drake’s “Way 2 Sexy” and feature the user just staring into the screen.

The use of the term “pureblood” comes as the U.S. sees an upward trend in COVID cases amid the Delta variant spread. U.S. health officials continue to push for Americans to get vaccinated, with about 55% of the eligible population fully vaccinated against the virus.
