First of all, I think just the "rare" clotting disorders already reported in the media have caused a large reduction in people getting vaccinated. In my area this weekend two thousand vaccination appointments are reported to be going unused at just one mass vaccination site.

I wanted to find confirmation of exactly what proteins are being created by the mRNA experimental injections and found the article linked below indicating that the current mRNA vaccines induce the creation of the full length of the spike. "Full-length spike" implies that it INCLUDES the cell-latching S1 protein shown on the tip of the spike in the graphic also linked below.

It is suggested in this article (written before the 8 Mar 2021 study revealing the S1 protein pathology) that future vaccines may beneficially use just the S1 protein.

Full-length spike vaccines

Several vaccines that incorporate the full-length spike include the Oxford/Astra-Zeneca adenovirus vector vaccine (ChAdOx1 nCoV‐19), Ad5 vector, the LNP- encapsulated mRNA vaccines from Pfizer/BioNTech (BNT162b2) and Moderna (mRNA‐1273), and the Novavax vaccine that uses the recombinant spike protein (NVX‐CoV2373).

S1-based vaccines

The S1 subunit has a unique advantage as a potential vaccine candidate, in that both the RBD and the NTD are located on this subunit. It is strongly immunogenic and induces neutralizing antibodies. Candidate vaccines using the S1 subunit include one using a microneedle array using recombinant S1-Fc fusion protein (Fc being an immunoglobulin component), and one based on a recombinant inactivated rabies virus platform.

"Once it locates a human cell, part of the spike protein known as S1 latches onto a receptor on the surface of the cell. The S1 protein falls off, leaving an attached segment the S2 protein which inserts itself into the cell.":

Anyone have any similar tech details on the J&J experimental injection?
