Thousands of babies are being born with small heads and brain damage... Review ConsiderEngage Decide Would you test a vaccine? A previously mild illness, Zika is now causing panic in South America.

  9. 9. Student sheets A C E G I B D F H J How the vaccine works SS1 The vaccine contains inactive versions of the Zika virus. The vaccine contains active Zika viruses. Your red blood cells realise that the virus is an invader. They create antibodies that stick to the spikes on the virus and destroys them. They create antibodies that stick to the genetic material in the virus and destroys them. The viruses are released into your skin. The viruses are released into your blood. If later you are infected with Zika, your immune system recognises the spikes on the surface of the viruses. They are destroyed before they get a chance to multiply and make you ill. If later you are infected with Zika, your digestive system recognises the spikes on the surface of the viruses. They are destroyed before they get a chance to multiply and make you ill. Your white blood cells realise that the virus is an invader.

  11. 11. Student sheets Sources Member of your family A friend Science teacher Doctor SS3a I have family in Brazil. A vaccine would keep them safe. You will be given an untested vaccine. It could harm you – let someone else try it. A vaccine, like any medicine, carries health risks. However, in tested vaccines these are very rare. We need to test new vaccines on people to check they work and are completely safe. Without this no new vaccines can be developed.
  12. 12. Student sheets SS3b Sources The Zika vaccine is being developed much more quickly than normal so it gets to people at risk as soon as possible. TV news Drug company website The vaccine has been tested in humans before and shown to be safe. The health of the volunteers will be checked daily by doctors. Newspaper The zika vaccine will contain toxic mercury and other chemicals, it’s more harmful than getting zika #antivaccine Selena McCarthy @selenam Celebrity tweet

Editor's Notes

  • Ask the class for a show of hands: who would say yes, no or not sure?
    At the end they will vote again, to see if the process of becoming more informed has changed their minds.
  • The learning objectives for this lesson.
  • Ask students how the structure of a virus is different to a living cell, how is it similar?
  • Arrange students into 8 groups and give each group one sentence taken from SS1.
    Ask groups to read out their sentence if they think it correctly describes what is happening in each image. (Some groups will have sentences which contain incorrect science so are not used). Ask the rest of the class if they agree that this is correct.
    The correct answers are: 1C, 2H, 3D, 4E, 5I
  • Ask students to write down which three sources from the slide that they think would be the most useful.
    After competing the task on SS2-3, discuss what the students found out:
    Is testing the vaccine the best outcome for you? For others?
    Does anyone have an outcome where testing the vaccine has more risks for them but more benefits for others - would they still test it? Why?
    Which sources were more reliable? Why?
    Did the three sources you choose end up being the best choices? Why/why not?
    Why is the risk of catching Zika from the vaccine 0? (This relates back to the science)
  • Students work alone. They write down their decision and explain how they made it. They should mention how they weighed up the benefits and risks.
    To vote online, click the black box or go to http://www.engagingscience.eu/en/2016/03/04/zika-new/
    The key to the percentages in the voting is: : 80-100% = 24-30 students in a class of 30, 60-79% = 18-23 students, 40-60% = 12-17 students, 20-39% = 6-11 students, 0-19% = 0-5 students
  • Students walk round the class, read the sources (SS3) and fill in the sheet to show how big each risk/benefit is.
    Please note: for older students you may wish to remove the risks and benefits from the table and ask them to add them in themselves.
    The students decide on how big each risk is and then add up the numbers in each column. You may wish to model how to do this.
  • Display the sources at different places around the room.
