Could a New Vaccine Formula XFG Give Pfizer (PFE) and BioNTech (BNTX) a Post-Pandemic Revenue Boost?
Pfizer (PFE) and BioNTech (BNTX) received FDA approval for their updated COVID-19 vaccine, COMIRNATY XFG, targeting the XFG variant. The approval secures their position in seasonal COVID-19 immunizations, providing a stable revenue stream. For Pfizer, this supports cash flow and pipeline investments, while for BioNTech, it validates its mRNA platform and maintains market share. Both companies face risks from potential demand declines and market contraction.
