Under no circumstances should the vaccine be administered intravenously or intradermally.
Before vaccination, the history of the child should be studied, paying attention to the previous administration of vaccines and the associated occurrence of adverse reactions, as well as to conduct an examination.
As with the introduction of any other vaccine, you should have ready everything you need to stop a possible anaphylactic reaction to the vaccine.The vaccinated should be under medical supervision for 30 minutes after immunization.
The occurrence of the following reactions after vaccine administration is not a contraindication for subsequent vaccinations, but the benefit / risk ratio should be taken into account:
- temperature ≥ 40 ° C, which occurred within 48 hours;
- a collapse or shock-like condition that developed within 48 hours after the introduction of the vaccine;
- a shrill scream lasting 3 hours or more, which occurred within 48 hours after the introduction of the vaccine;
- febrile or afefrilnye convulsions that occurred within 3 days after vaccination.
As with any other vaccination, in some cases, a protective immune response may not be achieved.
The vaccine does not prevent the development of diseases caused by any other pathogens, with the exception of Corynebacterium diphtherial, Clostridium tetani, Bordelella pertussis, hepatitis B virus, poliovirus 1, 2, 3 types. However, a prophylactic effect is expected for hepatitis D, which can be prevented by vaccination, since hepatitis D (caused by the hepatitis virus delta virus) does not occur in the absence of hepatitis B virus.
HIV infection is not a contraindication to vaccination.However, after immunization of patients with immunodeficiency, the expected immunological response may not be achieved.
In children with progressive neurological disorders, including infantile spasms, epilepsy or uncontrolled progressive encephalopathy, pertussis vaccine (both whole cell and acellular vaccines) should be postponed until stabilization. The decision to prescribe a vaccine with a pertussis component should be taken individually after a thorough assessment of the benefits and risks.
It is necessary to take into account the potential risk of apnea and the need to monitor respiratory function for 48-72 hours with primary vaccination of children born prematurely (<28 weeks gestation), and especially children with respiratory distress syndrome. In view of the need to vaccinate children of this group, the primary vaccination should not be postponed or refused.
After vaccination, or sometimes in front of it, fainting or severe weakness is possible as a psychological reaction to injection. Before vaccination it is important to make sure that the patient does not get injured in the event of a syncope.
The presence of febrile seizures in the anamnesis, as well as seizures in the family history or the syndrome of sudden child death is not a contraindication, but requires special attention. Such vaccinated should be observed within 2-3 days, since during this period an undesirable phenomenon may occur.
