Hi all. Not done this before..   

I was diagnosed with breast cancer which has spread to lungs and liver... HER2  so managable so far.   Feel fine and gone through Chemo... now on Immunotherapy treatment.    My questions are:

1. Has anyone has the new pertzamab/Trastuzumab injection treatment and did you have any side effects and..

2. My friends are asking me to go on a 3 day mini cruise in August.   I am fully vaxed for Covid but unsure whether my immune system is still a concern..

Any advice would be much appreciated  xxx
