Why this lesson matters
Students benefit from simple, practical language for noticing when they feel unwell and understanding why immunisations are part of staying healthy. Keeping safe is not only about responding once illness happens. It also involves helping students build early skills for noticing change, making safer choices and knowing when to ask an adult for help. This lesson supports a proactive approach to health, helping students understand that looking after their body, including through habits like immunisation, is a normal part of staying well.

Teaching notes & Delivery Considerations
This lesson includes content about unkind behaviour, exclusion and asking adults for help. It should be taught with calm, clear discussion norms.
Before teaching
Remind students not to share private health details about themselves or others
Frame discussion around general examples rather than personal medical experiences
Check whether any students may need additional support around health related discussion
Be prepared to follow your school's child safety, wellbeing or child protection procedures if a student discloses harm or says they feel unsafe.
During delivery
Use simple, everyday language when describing signs of illness
Keep the explanation of immunisations broad and age appropriate rather than clinical
Reinforce that the lesson is not medical training and does not replace advice from a doctor or nurse
Allow students to respond through discussion or simple written or drawn reflection depending on confidence
Supporting safe discussion
Reinforce that telling an adult about feeling unwell is a responsible choice
Avoid asking students to share personal or family medical information
Encourage general examples rather than naming classmates or family members
Adaptation options
Spend more time on identifying trusted adults if students need extra support
Use partner discussion for quieter groups and whole class discussion for confident groups
Extend the healthy habits component if your school is focusing on a broader keeping safe or healthy lifestyle unit
