@LUCY_BC that's great news to have your shot booked. I assume your medical team is aware and in agreement on timing. If not, don't leave to the last minute. Ensure they know now, especially given your reaction to your chemo. They may want to adjust your treatment to allow for the Covid shot like my oncologist did for my first shot.
But good luck with your chemo. I too had severe reaction to Taxol five years ago. For me it was within the first 60 seconds and so severe I was sent up to acute care for monitoring for seven hours. They abandoned the drug entirely for me and substituted Gemcitabine which I tolerated just fine. This time I ended up reacting to Carboplatin at cycle 5. I'm told the platinum based drugs build up toxicity over time so reaction later on in the treatment schedule is quite normal. We tried again with more drugs and slower infusion but no go, so I'm now on Cisplatin with lots of pre meds and all seems ok although the side effects with Cis are much harder on me than were the effects from the Carbo. At least I'm at the end of my overall treatment. Cycle 8 this week and next and either over or we'll go one final cycle.
Oh, a suggestion to ask your medical care. Given you continued to develop rashes/reactions for several days after your chemo has anyone suggested you keep a supply of antihistamines handy..Benadryl or Claritin perhaps? They can be very effective in moderating an allergic reaction depending on your situation. If it hasn't been suggested, you might want to ask whether that might be an effective strategy to help you through your chemo. Not necessarily relevant for everyone however.
We'll all be thinking of you. Let us know how it goes. Hopefully uneventful this time. <3
