"How can the vaccine be produced faster?"
Although this can be a risky plan and might not work, I have done lots of thinking, and my dad also gave me this idea. If the United States were to buy private vaccines like Johnson & Johnson, they can deliver the serum to laboratories so scientists who have the ingredients to make the vaccine can produce it (Pfizer, BioNTech, Johnson & Johnson, Moderna, and NIAID). If the United States does this, the vaccine can be produced 17 times faster than before, which is just the US.
