There is a small risk of developing Guillian-Barre syndrome with the flu vaccine. The chances of this have been markedly reduced in recent years. Nevertheless it remains a small risk and while most recover, there is a potential of long term problems and even death from this reaction.
Thanks for your question.
It would be a great idea to give all of the vaccines at once. It is chosen to space them out because their effectiveness can be altered by factors such as other vaccine interactions and age of the patient. So the governing bodies of experts do their best to give the vaccines early enough to be effective and in combination as much as possible to reduce the needle sticks. More work will be on going to get this to be even better.
Thanks for your question. Appetites change frequently in toddlers. The change in your son’s eating habits is not related to the vaccination. The best way to know if a child is getting adequate nutrition is to have his growth measurements checked by a provider. If he is still growing well we would not have concerns. ‘Picky eating’ may be a phase he is going through or a desire to have different foods. You should continue to offer food varieties at a sit down family meal, offer few if any snacks (and if you do offer snacks make sure they are healthy, and limit sweeten beverages which could curtail appetite. But importantly check with your provider who will measure his growth, take a more detailed history, and offer dietary advice.
