Edible algae vaccine Edible algae vaccine Edible algae based vaccination is a vaccination strategy under preliminary research to combine a genetically engineered sub-unit vaccine and an immunologic adjuvant into "Chlamydomonas reinhardtii" microalgae. Microalgae can be freeze-dried and administered orally. While spirulina is accepted as safe to consume, edible algal vaccines remain under basic research with unconfirmed safety and efficacy as of 2018.

The vaccine was grown in "C. reinhardtii" algae
