In most cases, immunization of children does not cause any adverse reactions. However, if they do occur, vaccination reactions can be classified as local and general.
Do local reactions include swelling and redness at the injection site. They are generally minor and will disappear after 1-3 days. Excessive vaccine reactions are rare. In this case, especially if the process also includes joints, it is necessary to visit a doctor who will determine the cause of this symptom and implement appropriate measures.
It is one of the specific local reactions reaction after vaccination against tuberculosis (BCG), performed right after birth. It lasts a long time and can vary in size and appearance – from a reddish-blue papule to a large, bubbling nodule. Either way, this is a normal vaccine reaction. Therefore, no preparations or dressings should be applied to the vaccine injection site, its contents should not be squeezed, etc. The exception is when the contents come out of the vaginating nodule. In this case, a protective dressing (e.g. a plaster with a dressing) should be applied to the site to prevent secondary infection of the lesion and its irritation by the clothes.
Systemic reactions after vaccination are usually low-grade fever or fever, and irritability resulting from increased temperature and pain at the site of vaccination. In such a situation, it is enough to give the child antipyretic drugs, which also have an analgesic effect.

– the so-called inconsolable crying after vaccination against whooping cough,
– lymph node reactions in the armpit after tuberculosis vaccination,
– generalized allergic reactions.
The occurrence of the above-mentioned reactions always requires immediate medical consultation.
