Bill Gates Defends Vaccines Amid Conspiracies—Why Is a Population Control Advocate 'Saving Lives'?

Bill Gates: "I had predicted there was a risk of a pandemic, and sadly that came true... I was completely taken by surprise [by all the 'conspiracy theories'], and some of them centred on me."

"And some of them were exactly the opposite of the truth. Vaccines have saved more lives than any other tool, and yet they came under attack."

Why would a man so obsessed with reducing the world's population care about "saving lives"?
