Pfizer-BioNTech's combined mRNA vaccine for Covid-19 and influenza failed to demonstrate a robust immune response against the influenza B strain in Phase 3 trial.
Pfizer-BioNTech's combined mRNA vaccine for Covid-19 and influenza failed to meet one of its primary goals in a Phase 3 trial.
While the experimental vaccine showed a robust immune response against the influenza A strain, it did not demonstrate a similar response against the less common influenza B strain.
The combination vaccine's effectiveness against Covid-19 was comparable to that of Pfizer-BioNTech's standalone Covid-19 vaccine, Comirnaty.
Pfizer and BioNTech are now considering modifications to improve the vaccine's performance against the influenza B strain and will discuss next steps with health authorities.
