how long ago did we start testing MRNA vaccines on people? oh that's right. Funny that 1955 was halfway into the infecting people with syphilis Tuskegee study but if you ask any boomer who was around back then they don't know about it. Its almost like our government has been horrible for a long time and the media and news coverage just never mentioned it until the internet came around and showed people the truth and even then its like most people don't want to look at it. They just don't care.
