Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: In just 2 sentences or less, summarize the main ideas of this text.

Like most Americans, Joe Burrow has been doing his best while trying to ride out the novel coronavirus pandemic. In the interim, he's once again doing good things for his hometown while sheltering in Athens, Ohio, for the past month.

And more than ever, he sounds like a guy who's pretty comfortable with the thought of suiting up for a certain NFL team on the other side of the state.

Burrow, the 23-year-old reigning Heisman Trophy winner expected to go to the Cincinnati Bengals with the No. 1 pick when the NFL draft begins Thursday night, is currently doing his best to make the most of grim circumstances.

"A lot of Skype meetings," Burrow told USA TODAY Sports on Tuesday when asked to describe what's been the strangest of pre-draft processes. "In some ways it's been less distracting after this quarantine hit.

"I've really been able to focus on my body – weight training and speed training and throwing. I haven't missed any days flying across the country meeting with a franchise. So it's been interesting, but in some ways very good for me."
Response: Joe Burrow is expected to be taken by the Cincinnati Bengals with the first overall pick in the draft. Like many Americans, Burrow is adjusting to life in the pandemic, settling for Skype meetings with teams rather than flying cross country for an in-person meet.

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Summarize how vaccines work to protect against diseases.

Vaccines stimulate the immune system to recognize and fight specific pathogens by introducing a harmless component or a weakened version of the pathogen. This prepares the body to respond quickly and effectively if exposed to the actual disease in the future.
