I have been on Tamoxifen for 3 years now and have had all my flu and Covid injections. I have been called for the spring one too. I have had no reaction with these. So it will be interesting what the Breast Care Nurses say. Take care

Thanks for the reply, i am sure it has been asked but i suppose its best to make sure before i have any.

I too have had all my covid jabs and have been called for the spring one

I am on Tamoxifen and have also been called for my Covid jab. It is over a year since my surgery and radiotherapy. It says I need to prove I am vulnerable when I get the jab and I am not sure if being on Tamoxifen is enough justification. I hope it is as I would like to get the vaccine update.

Hi mummyknapp,

Thanks for posting.

A seasonal COVID-19 booster is available for some people which you can read more about here.

You’ll see from our information that hormone therapy such as tamoxifen , does not typically affect your immune system. Therefore, it shouldn’t reduce the effectiveness of the vaccine, and it should be safe to have the vaccine.

Hopefully this is helpful for @jan_del_mar as well.

You explain having had bilateral mastectomy. We’re not sure whether you have had surgery to your lymph nodes on both sides as well and therefore at risk of lymphoedema. If you are at risk of developing lymphoedema you may be concerned about having the vaccine in your arm. Although there is not any strong evidence that having injections, in your ‘at risk’ arm or arms will cause lymphoedema, you may wish to choose to have the vaccine injections in the unaffected arm or in the thigh.
