Is it bad to take my baby outside?

It’s sad. My husband is really angry at me for taking my baby out, he is 7 months old and he keeps on telling me that we should’ve stay at home because our son is not yet fully immunized/vaccinated. i really don’t get it, he also brings fear to us telling stories of his workmate’s kids rushing to the ER because of respiratory diseases. I always make sure our son is in proper clothing when we go outside and I never take him to overcrowded places. He thinks that we always go somewhere that is not kid-friendly places but we only go somewhere like outside the neighborhood, grocery stores, malls, parks. I’m in despair. I do have PPD/PPA and going outside helps me, I want to live my life too with our son.😢
