Yes there were vaccines from Jan 2020 and absolutely in April 2020
Here in Dallas they were giving out vaccines at selected sites including Fair Park
This may have been nothing more than a ploy
But it is wrong to say there was no vaccine on April 3rd when vid was posted to YouTube
The first Covid vaccine in the USA was administered in December 2020. This video was posted in April of 2020.
You simply are mistaken.
The vaccine manufacturers deliberately held back the vaccines until after the election. Therefore no vaccines in April 2020. April comes before November.
