Worthy to note:
-The U.S. Food and Drug Administration has granted emergency use authorizations for three COVID-19 vaccines so far.
There is a big difference between emergency use authorization and full approval which usually takes years for the FDA to grant.
What technology does each vaccine use?
What about safety and side effects?
What do we still need to know?
It remains unclear how long any of these vaccines will continue to protect people. While the small number of early trial participants have maintained levels of protective antibodies for nearly a year, companies will continue to follow volunteers for two years to see if their immunity begins to wane. Periodic booster shots to extend immunity and/or protect against new variants of the virus might be needed.
And although a growing body of research suggests that vaccines will also protect people from passing on the virus – even if they don't have symptoms – that remains to be confirmed.
Since the FDA has not granted full approval to any of the vaccines, anyone who has taken it, is a volunteer, without indemnity or compensation of any kind.
