What is Cell-based vaccine?

Cell-based vaccines are developed from mammalian cell lines rather than the more common method which uses the cells in embryonic chicken eggs to develop the antigens. The potential use of cell culture techniques in developing viral vaccines has been widely investigated in the 2000s as a complementary and alternative platform to the current egg-based strategies.

Vaccines work to prepare an immune system to fight off disease by generating an immune response to disease-causing agents. This immune response enables the immune system to act more quickly and effectively when exposed to that antigen again, and is the most effective tool to date to prevent the spread of infectious diseases.
