Why Covid-19 Vaccines Aren’t yet Available to Everyone

>Typically, vaccine manufacturing doesn’t begin until a candidate has proved to be both safe and effective in animal and human testing. In the past, that process could take ten years; Pfizer’s vaccine, which was developed in collaboration with BioNTech, a German biotechnology company, took a record ten months.

This seems terrifying to me, especially combined with the headline.

Perhaps the fact that the vaccines are "not available to everyone" is not such a bad thing.

Considering the risk the virus poses to young, physically fit people is extremely low should we really be pushing such a new and unproven medical procedure onto them?
