Excerpt (see link above for details):

There are a number of peer-reviewed publications now providing reasons why mRNA vaccination could potentially cause an increased risk of COVID infection, or have other risks:

1. The well reported drop in white cell count (neutrophyls) immediately following vaccination.

2. Immune focus on a single antigen (spike protein) and associated variant selection causes vaccine break-through.

3. Antibody dependent enhancement; anti-SARS-CoV-2 antibodies could actually exacerbate COVID-19 through antibody-dependent enhancement (ADE).

4. Vaccine induced auto-immune responses including VITT.

5. Natural immunity provides better protection.

6. A jab in the arm can’t work, according to the Journal of Immunology.

7. Vitamin D deficiency.

8. The spike protein may itself toxic and prevent DNA repair.

9. According to the Journal of Immunology Original Antigenic Sin, or OAS.
