Sacroiliac pain (pain along the low back) reported in a series of patients who had COVID-19 reinfection in Iran. It limited their movement, but resolved in 2 weeks.

This is interesting. I have seen the same problem in India, specifically at reinfection.

🔹Longer 4 month interval between doses generated stronger immune response (mRNA, humoral) than 1 month (16 vs. 4 weeks)

This ~explains the quick waning in nations that used short gap

🔹1 dose might be enough for those who had prior infection (2nd dose did not add much)
