Vaccines and Immunity word search, scramble and crossword puzzle

I made this vaccines and immunity puzzle set for my Year 5 and 6 pupils during our health unit. The kids had heard about jabs but had no idea what vaccines did or how the immune system worked. So I put together a word search, a word scramble, and a crossword using words like vaccine, immunity, antibody, pathogen, booster, syringe, mRNA, white cell, herd immunity and autoimmune. Nothing fancy — just puzzles to help the vaccine vocabulary finally stick in an age-appropriate way.

The set is six pages. Three puzzles plus answer keys. The word search works well for quiet time after break. The scramble gets them talking because they argue about whether a vaccine gives you a mild version of the disease. The crossword I use for partners. I added a couple simple bandage, syringe, and shield drawings but nothing too scary or busy.

Works for Years 5 to 6. Print and go. Sometimes I have early finishers write one reason people get vaccines on the back. The kids actually ask for these now.
