Question
My child is 1 year 7 months old. A few days ago Nurse invited to the vaccination against measles, rubella, mumps. Read the instructions to the drug “Priorix”. In the “Special Instructions” is written: “For children who received immunoglobulin or other blood products, human vaccination is carried out not earlier than 3 months, due to the possible failure as a result of the impact of inaction on antibody vaccine viruses of measles, mumps and rubella.”
1.5 months ago a child was sick and viral infection on the orders of the district pediatrician took “Nazoferon.” I remember your words: “Interferon – a blood product,” read the instructions in “Nazoferon – the drug, based on – recombinant human interferon alpha-2b».Draw the conclusion that the vaccine should not do it now, you have to wait another 1.5 months.
I understand that the clinic vaccination would have done. It turns out that nobody cares what she might have turned out to be ineffective!
I suppose that our pediatrician is no exception to the rule, and pay no attention to it, if not all, many pediatricians, guided by the principle of “no harm, the inefficiency is only possible, but do need vaccinations – a” tick “in the magazine” . And then the opponents of vaccination trumpeting: “Vaccinations are not needed, vaccinated children still get sick.”
But perhaps I made the wrong conclusions, and nazoferon – this is not the drug, which is written in “Special Instructions” manual?
Answer
Conclusions have you really done wrong.
Yes, in the blood of most adults (which, strictly speaking, are the donors of the blood used to prepare immunoglobulin and other drugs), usually have antibodies to measles, rubella, mumps, and these antibodies can definitely make vaccinations ineffective (or not enougheffective). Hence, in the manual and the section “Specific instructions”, you studied in detail.
Nevertheless, recombinant interferon has no relation to medications, which are prepared from human blood. Production of recombinant products is carried out by specific biotech and no contact with human blood in the production process there. There is not only the recombinant but also human leukocyte interferon (one that drip into the nose), but in this preparation are whatever antibodies (immunoglobulins) are absent. The conclusion is – the use of drugs on the basis of leukocyte and recombinant interferons has no influence on the conduct of immunization, ie, vaccine in this situation and do possible, and necessary.
Please note: we are not discussing the question whether in principle the use of interferon preparations for SARS, we simply fix the attention on the fact that these drugs is no direct connection with the vaccination does not have
