Hi... Not all children develop allergy  or disease after meat or milk products... Most children are doing well on meat and milk foods... Some children may not tolerate cow's milk or specific meats... Not all information in the internet is true... And even  if true it may not be applicable to your case... As far as Vaccines are concerned many of the Vaccines have saved  many lives and have contributed much to the well being. .. There are some rare  side effects for the Vaccines ... So it's risk vs benefit... Vaccine schedules are available for each country...in India it is by Indian academy of pediatrics... Pls see the website for details...
