You can take your dog out before his jabs, just don,t put him on the ground and mix with other dogs. We took Dylan out shortly after we got him, to get used to the car, carried him along the prom, on the beach, round the shops (outside), met my hairdresser, just to get him used to people and noises. He was eight weeks when we got him, so it would have been a while to wait til two weeks after the jabs, and we are in such a quiet place he wouldn’t,t see anything or anyone. Once he was over his jabs, we took him to puppy classes, so I guess it would have been between three and four months old IIRC. Sooner the better I think.
Enjoy your pup!
Lesley and Dylan
