Summarize the main events and outcomes described in the following passage:

On May 12th, the World Health Organization confirmed the first-ever vaccine to fight malaria, one of the oldest and deadliest diseases. The vaccine, called Mosquirix and developed by British drugmaker GlaxoSmithKline, will be rolled out in sub-Saharan Africa and other regions with moderate to high malaria transmission. In a large trial, the vaccine was found to prevent about 4 in 10 cases of malaria over a four-year period, making it the first to clear the required 75% efficacy goal. While not a complete solution, health officials see it as a crucial new tool to prevent the disease that kills around 500,000 children each year.

The World Health Organization approved the first ever malaria vaccine called Mosquirix, developed by GlaxoSmithKline. In a trial, the vaccine prevented about 40% of malaria cases over four years. While not completely eliminating the disease, the vaccine will be rolled out in sub-Saharan Africa and other high-risk regions as a crucial new tool to help reduce the 500,000 child deaths caused by malaria annually.

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: Please give me a summed up version of the following:

Fox News reached a last-second settlement with Dominion Voting Systems on Tuesday as the case raced toward opening statements, paying more than $787 million to end a colossal two-year legal battle that publicly shredded the right-wing network’s credibility.

Fox News’ $787.5 million settlement with Dominion Voting Systems is the largest publicly known defamation settlement in US history involving a media company.

The deal was announced hours after the jury was sworn in at the Delaware Superior Court. Rumors of a settlement swirled in the courthouse when, after a lunch break, the proceedings dramatically ground to a halt for nearly three hours with no explanation, while the parties apparently hammered out an accord.
Response: Fox News settled with Dominion Voting Systems and paid more than $787 million after two years of legal battles for a defamation suit. Just before the settlement, the jury had already been sworn in, and there were three hours of no information being shared while the settlement was made.

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.
