The data shows the top 10 global pharmaceutical companies based on their vaccine revenue market share worldwide in 2017, and a projection for 2024. Pfizer is expected to account for some 16% of the global vaccine market by 2024, largely due to success with its pneumococcal vaccine, Prevnar 13. A vaccine often contains an agent that is made from a weakened form of a disease microbe, that is then used to stimulate the body's immune system to destroy and recognize the microorganism in case of later exposures.
