Vaccine and breastfeeding 8 mth old

Hi. I am actually strongly against getting vaccinated for now as i am still breastfeeding and planning to only take the vaccine once i stop bf, that is when my baby turns 2. Reason being im scared if it's gonna affect my baby 🤷🏻‍♀️. And im also alil scared of the swab test. But my bil's wedding is in a few mths time so I'm considering to take it. Anyone has taken it while breastfeeding, and for hw long hv you taken it and how are you now? Jz need some advice and experiences. I cnnt not go to tge wedding. TIA !!
