Moderna. First shot at the end of January (Texas priority 1B), no aftereffects at all. Second shot at the end of February; no fever, but some muscle pain, not only at the injection site. Played it up a bit, to avoid yard work for the weekend. Then wifey asked if I, instead of doing yard work, could help her a bit with her NIH grant. So, instead of 4-6 hours yard work, I spent 12+ hours proofreading, editing, and making diagrams.
