Thanks for posting a really good article.
Does the vaccine cross the blood brain barrier and alter spinal fluid?
Yes.
S says: 11 January, 2021 at 8:38 pm Good information. Yes, a recent paper has been published in Nature Neuroscience entitled “The S1 protein of SARS-CoV-2 crosses the blood–brain barrier in mice” to uncover its ability to cross Blood Brain Barrier. Which tissues will mRNA vaccine target exactly? A little alarming situation, this. Would be better if more information by vaccine companies are provided rather than getting anxious on trade secrets.
