Pfizer and BioNTech have encountered a setback in their efforts to develop a vaccine that protects against both influenza and Covid-19, leaving the field open for Moderna to advance its own combination shot. Pfizer’s combo shot showed weaker immune response against influenza B compared to licensed flu vaccines. Moderna’s experimental combo shot performed better than standalone flu and Covid-19 shots in a large Phase 3 trial, prompting investors to shrug off the news and show support for Moderna. Pfizer will consider adjustments and discuss next steps with health authorities. The demand for Covid-19 vaccines has been declining, affecting sales projections for both companies.
