BCG Vaccine issue. Again and where?

My baby boy was vaccinated by BCG a week after he was born. He was vaccinated in a government health center. As I observed during the process, the vaccine did not penetrate into the skin and was totally drained after being injected that supposed to make a small lump on that area. Me and my wife waited for the swelling in that area but it did not happen. Now he is already 1yr and 4mnths old and still no swelling happened not even a small scar. I raised this concern to the health center and they advised us to just get a booster on his 5th or 6th birthday if I remembered it correcty. But the situation has change since my wife's brother was suspected to have a TB after being examined in a medical center. I would like to ask if the vaccine will be effective in protecting my child against TB given on how it was administered? If not, when can we have our child properly vaccinated again and where? Please I need advise Doc. Thank you in advance and hoping to get a response with you Doc.
