Most Americans say they prefer a specific brand of vaccine – and what they've seen on social media influences their decision

Millions of Americans are receiving their COVID-19 vaccines, and in a world of over-sharing on social media, that means Instagram and Twitter feeds are also being flooded with shots. People are not only sharing when they receive their vaccine, but also which vaccine they receive, often using hashtags like #PfizerGang or #TeamModerna.

Nearly three-quarters of Americans say they prefer a specific vaccine brand by name, according to a recent survey of 1,000 people by M Booth Health, a health communications consultancy, and Savanta, a market research and advisory company. The survey found the largest share — 36% — preferred Pfizer. Moderna came in second with 19%, closely followed by Johnson & Johnson at 17%.
