Asad Haider asked about the factors influencing the decision to announce infant data (PD3 and PD4) sequentially or together, and the key developments Vaxcyte is monitoring in the PCV competitive landscape.
Answer
Grant Pickering, CEO of Vaxcyte, outlined the competitive landscape, noting Vaxcyte's lead with its 31-valent vaccine over GSK's Phase 1 30-something candidate and Pfizer's Phase 2 25-valent program.
