Paper out of Japan highlighting increased thyroid autoimmunity after covid vaccination.
Morita, Shuhei, et al. "Effect of SARS-CoV-2 BNT162b2 mRNA vaccine on thyroid autoimmunity: A twelve-month follow-up study." Frontiers in Endocrinology 14 (2023).

This was also review previously in another paper with no concern highlighted.
The effect of the BNT162b2 vaccine on antinuclear antibody and antiphospholipid antibody levels

The difference is that the Japan paper looked over 12 months, versus 2 months in the other paper.
Long term risks are not fully elucidated.
