It Took a Lot of Money and Resources
Quick Summary: To get safe and effective COVID-19 vaccines developed quickly, a ton of money was spent, and a lot of scientists worked on it.
One of the reasons that most vaccines take longer to develop is that there aren’t a lot of people working on them. Because COVID-19 is a pandemic, many wealthy countries wanted this vaccine to be developed because suddenly they were at risk. COVID-19 impacts everyone, which meant wealthy governments cared enough to put a ton of money into it, and a bunch of scientists who would normally be doing other things started working on it. It is a sad truth that diseases that only infect countries with fewer resources or people whose governments don’t care as much about them do not get developed as quickly. Although this is a sad reality, it does explain why the COVID-19 vaccine was released so quickly. In the 1980s and 1990s, people in power in the United States and other wealthy countries thought that HIV and AIDS only impacted LGBTQ+ people and people in Africa, so they didn't care and didn't put much money or work into developing vaccines or treatments. For COVID-19, they put in the work they should have put in for HIV and AIDS from the start.
