Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be seasonal factors at play. Has this 15% drop been compared to the same quarter last year?

Why it matters: Seasonal variations could explain temporary fluctuations. Expected answer: Yes, it's been compared to the same quarter last year. Impact on approach: If not seasonal, we'll focus on other factors.

• Considering market dynamics, I'm curious about competitor activity. Have there been any new vaccine entrants or significant marketing pushes from existing competitors?

Why it matters: Competitive pressures could be driving the sales decline. Expected answer: No major new entrants, but increased marketing from competitors. Impact on approach: We'd need to analyze our marketing strategy and product differentiation.

• Thinking about product lifecycle, I'm wondering about the vaccine's patent status. Is Prevnar 13 nearing patent expiration in any European markets?

Why it matters: Impending patent expiration could lead to market anticipation of generics. Expected answer: Patent is still valid for several years. Impact on approach: If valid, we'd focus on other factors affecting market perception.

• Considering healthcare policies, have there been any recent changes in vaccination guidelines or reimbursement policies in major European markets?

Why it matters: Policy changes could significantly impact vaccine uptake. Expected answer: Some countries have adjusted their vaccination schedules. Impact on approach: We'd need to analyze the impact of these policy changes on our sales.
