Summary
Recombinant subunit and vector vaccines use specific antigens made in engineered cells.
In depth
Hepatitis B vaccine was made by yeast expressing surface antigen. Viral vector vaccines (adenovirus carrying spike gene) and DNA vaccines are other approaches. Safer than whole pathogens.
Recombinant protein vaccines are safe because they contain no live pathogen. Viral vectors deliver antigen genes; DNA and mRNA vaccines can be designed quickly once a sequence is known.
Key idea: genetic engineering makes vaccines faster to develop and more targeted.
