Silicone adjuvants are a type of adjuvant used in vaccines to enhance the immune response to the vaccine. Some of the key features of silicone adjuvants include:

They are made from silicone oil, which is a synthetic polymer that is biocompatible and non-toxic.

They can mimic the structure of viral and bacterial membranes, which can help to enhance the immune response to the vaccine by mimicking the structure of the pathogen.

They can also act as a depot for the antigen, which can help to prolong the release of the antigen and increase the duration of the immune response.

They have been shown to be effective in increasing the production of antibodies and T-cell responses.

They have a good safety profile, with no significant adverse effects reported in clinical trials.
