FWIW your reaction to previous vaccines/doses doesn't predict your reaction to future vaccines/doses. Up until my second COVID vaccine I had never had any reaction to any vaccine other than a bit of pain in the injection site. My first COVID shot caused zero symptoms. So I was surprised when my second shot caused a day of flu-like symptoms. My booster, however, caused no symptoms other than swollen lymph nodes in one armpit.
