(A) Mean IgG levels after 2nd vaccine in vaccinated PwMS (N=309) and healthy (N=48) and in unvaccinated COVID-19-recovered PwMS (N=29). (B, C) Mean IgG level in vaccinated PwMS (N=479) (B) or healthy (N=65) (C) at 3 time-points: <3months and 6 months from 2nd vaccine and <3 months from 3rd vaccine. (D, E) Correlation between IgG and time since 2nd vaccine in vaccinated PwMS (N=311) (D) or healthy) (N=46) (E). (F) Correlation between IgG and time since COVID-19 infection in unvaccinated PwMS. (G) mean IgG difference between male (N=107) and female (N=204) PwMS after 2nd vaccine. (H) mean IgG difference between non-smokers (N=166) and smokers (N=37) PwMS after 2nd vaccine. (I) Correlation between IgG post 2nd vaccine and BMI in PwMS (N=144). (J, K) Correlation between IgG after 2nd vaccine and age in vaccinated PwMS (N=311) (J) or healthy (N=46) (K). (L) Correlation between IgG and age in unvaccinated PwMS recovered from COVID-19 (N=38). Dashed horizontal grey line represents minimum seropositive border (log10(50AU/ml).
