Is any Vaccine Approved by the FDA? Not that I am aware of. All testing, screening and vaccines were given the go ahead under the FDA emergency use authorization (EUA). Meaning humans are the source of testing. The Lab rats get a break this go around.
That being said a large portion of the vaccine development was already completed under research for cold and flu vaccines since they are from the same virus. Science had a head start this time.
If you are vaccinated then why do you care if people get vaccinated or not? Did you not get the vaccine to prevent yourself from becoming infected with Covid? If you are worried then you really don't believe in the effectiveness of the vaccine.
While we are at it why don't we push for weight loss, give up smoking, drugs and the rest that led to major contributing factors and quit worrying about who gets vaccinated or not. Or does that count as your body your choice? I get confused what we can choose to do or not do these days.
