Pfizer retains top spot in vaccine maker rankings as Sanofi’s slide sparks ‘code red’ call

Pfizer again heads up a physician ranking of vaccine manufacturers, beating Merck & Co. and Moderna to complete an unchanged top three from the last edition of the survey. But, while the rankings held steady, the operating environment has changed quickly to reinforce the value of being in good standing with physicians.
ZoomRx generated the league table by asking 58 U.S.-based healthcare professionals (HCPs) about 14 vaccine manufacturers. Respondents graded the companies’ innovation, patient centricity, reputation, HCP centricity and promotions, generating data that ZoomRx used to give each manufacturer a score out of 100.
As happened when ZoomRx ran a similar survey in 2024, Pfizer took the top spot after achieving strong scores across all five dimensions. The Big Pharma scored 83 out of 100 after HCPs praised its innovation, reliability and sales execution in particular.
Merck took second place, scoring 48 out of 100 on the strength of its consistent quality, education and support. A score of 37 was enough to give Moderna third place, in large part because of the reputation for innovation and scientific credibility that it gained during the pandemic. In another repeat of the previous standings, GSK took fourth place with a score of 34.
AstraZeneca was the only new name in the top five. ZoomRx said the company built trust and improved HCP perceptions by being accessible and consistently supportive, resulting in it snatching fifth place away from Sanofi. The French drugmaker slipped to seventh, behind Johnson & Johnson in sixth.
