Rsv vaccine?!!!

So have any of you ladies have had the Rsv vaccine while pregnant?? On my last appointment they called me to see if I wanted to get if and they are going to pay me for it ... when they said that I’m not sure if I should trust it 🧐 others have told me that they are just trying to see if it works .... I just don’t want them to do an experiment with me and my unborn baby 😤 is my first baby and if everything is going well so far I don’t want to mess it up they want to give me the shot before 33 weeks I’m 28w3d and they wanted to give me the shot at 29 weeks 😖 of course I can cancel it I just said yes at the moment because they called me and started explaining not so much they just said I had to have 8 appointments and my baby 6 after she’s born I don’t really trust it
