In the case of RSV vaccines, adjuvants may be included to help stimulate a more robust and durable immune response against the virus.The mechanism of action of an adjuvanted RSV vaccine would depend on the specific adjuvant used. However, adjuvants can help activate and enhance specific immune cells’ activity, such as antigen-presenting T and B cells. This can lead to a more robust and targeted immune response against the RSV virus.
The spectrum of activity of an adjuvanted RSV vaccine would also depend on the specific vaccine candidate being studied. Ideally, an RSV vaccine would protect against various RSV strains and subtypes, including those that cause severe disease. Developing an effective and safe RSV vaccine remains an active area of research. Further studies are needed to determine the optimal vaccine design and adjuvant strategy.
