CY will not take the shot for flu prevention as he has too many vacc. to take. He has taken two shot of 肺鏈 already. he needs to take the third shot next months
In fact, after 6 months you may make the call. For CY, I will not let him take the shot as he has too many shots to take. My sister is a nurse. Her opinion is that before 1 year old should try to avoid unncessary shots as his body would be very busy to entertain the shots.
However, it would be up to you and should depend on whether your baby needs to be on the street frequently!
