Experts continue to express concern about the delta variant of the novel coronavirus, which has been rapidly spreading in the United States as of late.

Much of the concern has been centered around the unvaccinated, who have less protection against the delta variant, which has a higher transmission rate, as I wrote for the Deseret News.

The COVID-19 delta variant might have different symptoms. Here’s how to spot them

But Vivek Cherian, an internal medicine physician in Baltimore, told Insider that the delta variant could be even more troublesome because, well, it could create more variants.

  • “The worst-case scenario is if delta mutates into something completely different, a completely different animal, and then our current vaccines are even less effective or ineffective,” Cherian told Insider.

This essentially means that the delta variant may create even more dangerous variants for the vaccinated and unvaccinated.

This COVID-19 variant is ‘rapidly increasing’ in the U.S.

Time to stop those COVID-19 variants might be running out, Dr. Paul Offit told CNN.

  • “Vaccines are our only way out of this,” Offit told CNN. “Unless we vaccinate a significant percentage of the population before winter hits, you’re going to see more spread and the creation of more variants, which will only make this task more difficult.”

Offit — who is on the Food and Drug Administration Vaccines Advisory Committee — told CNN that getting people vaccinated remains the biggest challenge.

  • “You would have thought at the beginning of this, knowing that vaccines are our only way out of the pandemic, the hardest part would have been figuring out how to construct these vaccines,” said Offit, according to CNN. “The hardest part is convincing people to get it, which is remarkable.”
