Once the mRNA Covid vaccine is injected into your body it teaches your cells to make thousands of copies of the spike protein so that if your body is exposed to the virus later it will recognize it and be prepared to defend.
A tiny, tiny bit of this mRNA multiplies and teaches the body how to respond for a long time to come.
Education through subtle messaging produces this multiplying result.
A little bit of matzah at a Passover Seder each year reinforces in a child that message of faith and trust that they are being looked after. The shofar on Rosh Hashanah, fasting on Yom Kippur, eating outside in a temporary hut on Sukkot, dancing with the Torah on Simchat Torah etc. etc. these are critical Jewish mRNA.
Throughout life when we face a challenge Jews have known how to respond because injected into our cells are these carefully prepared messages that have passed the test of time.
