U can go ahead safely if treatment has been completed and gap of 8 weeks is there. If undergoing treatment u should consult ur yreating oncologist
Vaccine related events or side effects is a unlinked event and can happen to anyone
My best wishes
Next Steps
go for vaccination if not undergoing any other medical treatment presently
Health Tips
Double up your mask while going for vaccination, wear loose clothes like half sleeve t shirt etc and take shower and change clothes after coming home. My wishes👍
