Adaptations to existing vaccines account for half of vaccine R&D projects
The 2017 Access to Vaccines Index has evaluated the pipelines of eight vaccine companies: Daiichi Sankyo, GSK, Johnson & Johnson, Merck & Co., Inc., Pfizer, Sanofi, Serum Institute of India and Takeda. The industry is responding to cases where existing vaccines need to be adapted: such projects account for 48% of projects in the pipeline (43/89), with one project aiming for multiple adaptations.
