Whooping cough vaccine around babies

Is it normal for a new mother to want everyone that comes into contact with the baby to be fully vaccinated and boosted with the whooping cough?

The baby is 8 months old now and they originally said it would have it’s own immunity by 6 months, now the rules are staying in place forever it seems

I don’t know much about babies, I’m wondering if her request is reasonable? I’m not comfortable with getting a vaccine just to meet a baby once, especially since I haven’t been sick for YEARS I’m so healthy, I feel like I don’t need it
