Subunit vaccines Some traditional vaccines work by delivering viral proteins to cells. The technologies to manufacture those protein fragments vary, but companies are using insect cells and yeast.

"Subunit vaccines have been around for a long time, and they tend to be cheaper to produce, so that opens up more access to vaccines, especially in times of pandemic," Jaklenec says.

There are two types of COVID-19 vaccines available: mRNA and protein subunit vaccines. mRNA stands for messenger RNA, which is part of DNA that tells cells how to produce proteins.

Protein subunit vaccines take longer to make than mRNA shots. JN.1 and KP.2 are no longer common variants in the U.S. But as of mid-October, the common ones are closely related to those variants.
