Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.
These resources were created for remote use during the pandemic and are not designed for classroom teaching.
Lesson details
Key learning points
- Vaccines have had a positive effect on public health (e.g. the eradication of smallpox).
- Vaccination is not risk free as it can have side effects, but the benefits outweigh the risks.
- New vaccines are trialled, and are only approved for use when the benefits of the vaccination outweigh the risks.
- It is necessary to vaccinate a high proportion of a population against a pathogen to provide herd immunity.
- Herd immunity helps protect those who can’t or won’t have the vaccination.
Keywords
Vaccination - The process of administering a vaccine to an individual to create immunity to a pathogen.
Vaccine - A formulation that contains an inactive pathogen, or parts of it.
Immunity - Immunity is established after the body is first exposed to a pathogen's antigens, and enables white blood cells to respond quickly to the antigen when the body is re-exposed to it.
Risk - A possible negative outcome.
Herd immunity - When a high proportion of the population have been vaccinated against a disease, the spread is reduced and unvaccinated individuals may be protected.
Common misconception
The MMR vaccination causes autism.
The study by Dr Wakefield is highly flawed, and has been discredited. Many subsequent studies have found no link between the MMR vaccination and autism. Measles is a highly infectious disease that can have devastating consequences.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
