Which audience pain points does Adam Ringham address in his book 'I'm in your vaccines'?

Adam Ringham from here.

“I’m in your vaccines” is written for parents who are:

• Overwhelmed by technical, science-heavy vaccine debates and want a simple, short read
• Worried about vaccine safety and the aggressive current schedule
• Concerned that pharma and the CDC aren’t transparent and may be burying data
• Angry that manufacturers have legal immunity yet their kids bear the risk
• Unsure how to talk to friends, family, or doctors and want clear, science-backed talking points

Is there a specific type of parent or concern you want to focus on (new parents, already skeptical, dealing with an injury)?
