Patient's question:
Did the flu vaccine take effect immediately after the baby received it? Is it different every time for the flu? How should it be prevented? Medical history and treatment effectiveness: None. What kind of help do you expect: Can it prevent it on the same day?Doctor's answer:
In this case, the general body will produce immunity to the vaccine, which needs about half a month to be effective, so it does not take effect immediately on the same day. When the same influenza virus invades again, the body will produce additional antibodies, generating stronger resistance! However, the influenza virus mutates significantly, and the type of virus prevalent worldwide varies each time, so it does not guarantee 100% resistance to the influenza virus. The above is the advice on the question "Does the flu vaccine take effect immediately after being given to a baby?" I hope it helps you, and wish you good health!
