ABOUT MRNA VACCINES
(Pfizer & Moderna)
-
Your body naturally uses mRNA to send instructions when building proteins.
-
mRNA technology is new in vaccine production but is already being used in cancer treatment.
-
It has been studied for more than ten years.
-
The COVID-19 mRNA vaccines give instructions to our cells to make a harmless piece that looks like the “spike protein” on the surface of the COVID-19 virus.
-
Our immune system sees these fake spike proteins and builds antibodies that recognize them. In the future our immune system will now recognize when the COVID -19 virus enters the body and can fight it.

ABOUT adenovirus vector vaccines
(JOHNSON & JOHNSON)
-
Unlike the Pfizer-BioNTech and Moderna vaccines, which store the instructions in single-stranded RNA, the Johnson & Johnson vaccine uses double-stranded DNA.
-
The gene for the coronavirus spike protein was added to another virus called Adenovirus 26. Adenoviruses are common viruses that typically cause colds or flu-like symptoms. The Johnson & Johnson team used a modified adenovirus that can enter cells but can’t replicate inside them or cause illness.
-
This type of vaccine has been studied for decades.
