'The yield of recombinant proteins produced in plants has since increased substantially, suggesting that new edible plant-made vaccines could now generate meaningful immune responses.'

'In these trials, the proportion of immunized individuals who generated an immune response against the desired target was disappointingly lower than in clinical trials involving standard vaccines administered via the parenteral route, the scientists wrote in the article.

The fluid containing the virus is harvested from the eggs and used to create the injectable vaccine.Īccording to the Centers for Disease Control and Preventions (CDC) website, the most common method for make flu vaccines is using an egg-based manufacturing process – a method that has been used for more than 70 years 'The glucocerebrosidase enzyme, produced as an injectable protein drug called taliglucerase alfa for the treatment of Gaucher disease, is produced in a carrot cell culture rather than in actual plants.'Īccording to the Centers for Disease Control and Preventions (CDC), the most common method for making flu vaccines is using an egg-based manufacturing process – a method that has been used for more than 70 years.Ĭandidate vaccine viruses (CVVs) are injected into fertilized chicken eggs and incubated for several days so the viruses can replicate. 'The plant-made vaccines against influenza virus and SARS-CoV-2 are expected to be the first therapeutic proteins produced in whole plants for human use,' Fausther-Bovendo and Kobinger wrote in an article published in Science Magazine. Pictures is the process being done to make a potential COVID vaccine candidate Scientists propose using 'molecular farming,' which places DNA that creates proteins inside a plant cell that is than transformed into an extract to make a vaccine.
