Seems correct. Didn’t even get approval at all in the US and the company withdrew their application. So yeah. I don’t want to doubt the experiences of your relative especially when it was so close to the vaccination. Could’ve actually been a serious side effect. I just never heard of it in my circles. What I heard of were friends who got covid multiple times and contracting more illnesses like respiratory viruses or stomach bugs over time aka wrecking their immune system.
