Puppy advice needed. Should be done?

Hi I have a labrador puppy who is 2 months now we have started his vaccination and he has gotten 2 shots of parvo and distemper we do not take him outside but sometime my society kids come to meet him , today a child came to play with him we let him play then later while talking to the kid we got to know that he has dogs a lab and a Pomeranian who are around 3-4 years old he also told us that the dogs had ticks previously which were removed by the parent. Later I went to meet the parents who told me that their dogs are unwell and have an ear infection. They have also gotten the dogs complete vaccination done. Now to clarify my puppy never got in touch with the dog itself but he got in touch with the child is there any chance my puppy can catch infections? And if yes what should be done?
