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.
Genetic engineering makes safer, more targeted vaccines. Recombinant subunit vaccines use an antigen made in yeast or insect cells, such as the hepatitis B surface protein. Viral vector vaccines use a harmless virus (adenovirus) to deliver an antigen gene, and mRNA vaccines deliver instructions for the antigen directly.
Because no whole pathogen is used, they cannot cause the disease, and production is fast and scalable; mRNA vaccines against COVID-19 were designed within days of the sequence being published. Adjuvants boost the immune response.
Example: HPV vaccine uses virus-like particles produced in yeast.
