I don’t know about subtle difference between proteins and peptides, but I would say the relevant category is “recombinant vaccines” and I believe that the first such was the Hepatitis B vaccine approved in 1986. This used genetically engineered yeast to produce a protein from the virus that was harvested and injected into people.
