Biology Activity - How vaccinations help slow the spread of disease

Lesson plan for how vaccinations help slow the spread of disease. 
Video description for how vaccinations help slow the spread of disease. 

For students who have experienced the global COVID-19 pandemic, it is vital for them to understand how disease spreads, and what doctors and scientists try to do to try and minimize the spread of disease. Because the COVID-19 virus was a brand new organism in 2020, there was no vaccine any country could use to help slow down the spread. Many groups are trying to produce an effective vaccine, so when it comes back in the future (assuming it will be a seasonal virus, similar to flu viruses being seasonal in many countries) the vaccine can help many people not become seriously ill or die. 

This activity can help students better understand the importance of a vaccine, and how it can help reduce the number of people infected by the virus, and help reduce the number of people who will become sick or die.
