This is excellent news, but I have to wonder why it has taken so long. After all, it's not like this vaccine is particularly new - it's been around for a while and the rights to commercialize it were sold to a company that sat on it because there was no immediate profit. This speaks to a need for the Federal gov't to test medicines that have low or no profit potential, but are critical to have in place (e.g. new antibiotics to tackle resistant bacteria, medicines for rare diseases.
Still, good to see this underway.
