LowSerotonin

Hi everyone. I recently got my K1 visa and legally married my wife in the US. We are trying to proceed with getting my green card and I had a few questions about I-693. I was informed that I don't have to do I-693 if I did my physical eval within a year. However, I got my first dose of vaccinations in September and I haven't gotten my second dose yet. Do I still have to get my second dose of vaccination and fill out I-693? Or can I just skip this form since it hasn't been a year. Is it also possible for me to just get the vaccinations and not have to fill out the I-693? Thank you everyone in advance.
