All vaccinations are carried out in order to create immunity to a particular disease. Immunogenicity is one of the main terms related to this topic. In fact, it refers to the ability of the vaccine to induce adequate and desired response. Negative for the human body reaction called reactogenicity.
Each vaccine has its reactogenicity and immunogenicity.
All reactions after vaccination can be divided into two types:
Local stage of the reaction is determined by the width of the redness. If the spot has a width of 2.5 cm, then the reaction is easy. If redness has a diameter of 5 cm, then we can talk about the average response. If more than 5 cm, has a severe reaction.
Reduce redness virtually impossible. In this case, the parents should distract the child, to ensure peace, to give painkillers. Also the injection site can put a moist clean cloth.
After injection in the thigh or the shoulder may be a reaction of the lymph nodes. In this case, as well as, if redness has a width greater than 5 cm, should consult a doctor.
The most common reaction after any vaccine is fever. It is very undesirable in such a case, and therefore it is necessary to knock down, without waiting for 38 ° C. For this purpose it is expedient to use preparations of paracetamol and ibuprofen. In addition to these measures should also ensure the child is drinking plenty of fluids, humidified fresh air in the room.
Isolated in a separate category adverse reactions. This is an extremely negative phenomenon, in almost all cases need medical help. These include, for example, include the collapse and anaphylactic shock. Possible CNS and, as a consequence, convulsions, encephalopathy, meningitis, lesion of some organs (liver, kidney), a variety of allergic manifestations.
To avoid or at least reduce a negative reaction after vaccination can be due to the prevention of such situations.
1. The child at the time of vaccination should be fully healthy – this should confirm the doctors and clinical blood tests.
2. If the child is prone to allergies, then it is better before the introduction of vaccines to give the child antihistamines.
3. You should avoid contact of the child with sick people and after the procedure.
