The FDA is likely to issue emergency use authorization (EUA) for the top COVID-19 vaccine(s) before the year is out. That will allow people with higher risk of serious illness to get a vaccination before it receives full-blown FDA approval.
Emergency use would likely apply to people at risk due to age and health concerns, medical workers, and people whose jobs require travel and constant exposure to new people.
The big question mark is how well the vaccine will work in fighting off the virus in those who are exposed to COVID-19.
That will take time and a lot more testing to discover.
And we also need to understand how long the vaccine lasts. Will it work for two months? Half a year? Or a full year? This is, of course, the purpose of having clinical trials to determine safety, efficacy, dosing levels, and frequency of dosing.
Regardless, the availability of an effective vaccine, even under an EUA, would be a big step toward getting the economy back on track and displaced people back to work… and returning to a semblance of normalcy after what’s been an absolutely ridiculous year.
