Both the russian and chinese vaccines use chunks of proteins that are thousands (and likely tens of thousands) of amino acids long, in a mostly inactivated form.
The Russian vaccine, unlike the Chinese one, is not an inactivated virus. It uses an adenovirus vector for delivery of genetic material that makes the body’s cells synthesise antigen material, much like the AstraZeneca/Oxford vaccine.
