Can mmr, 5 in 1 and flu jab be taken together

Don't do it. The flu shot hasn't been tested for safety when taken with our vaccines. Read this... http://www.huffingtonpost.com/dr-bob-sears/flu-shot-safety-not-teste_b_749287.html

Not recommended. Maybe ask the doctor for their advise or recommendation?

Best not recommended too. too much vaccination at one go

Nope. Safer to separate. Too much at a time.
