Tdap vaccine -28 weeks

My OB gave me the TDap vaccine yesterday and today I’m SICK. Body aches, terrible headache, coughing up stuff and a slight fever.

I understand how vaccines work and why this is happening, but is it contagious? My baby shower is in 2 days...... it’s an outdoor thing and the tables will be spaced 6ft apart per household. But I still can’t possibly spread it to anyone else in good conscience.

I’ve had this vaccine before and this never happened (but immune systems are different during pregnancy). So I’m really not sure if this is something I can pass on to anyone else.
