Today you can get sick from various diseases - hepatitis, poliomyelitis, rubella, measles, yellow fever and many others, but during pregnancy it can not be done. What is the reason for this and in which cases can an exception be made? Features of immunity
To date, there is no scientific evidence that vaccines harm the health of a future mother and baby, but most obstetrician-gynecologists do not advise pregnant women to vaccinate. The fact is that it is impossible to predict the consequences of the drug administration, because experiments in this area are not conducted in humans.
The exact explanation of what a potential threat to a baby is, doctors can not give. There is an assumption that a virus introduced into the body with a vaccine can affect the child through the blood because the immunity of a pregnant woman has its own characteristics. For 9 months the organism of the future mother is being reconstructed, some organs, such as the liver and kidneys, begin to work in a new mode. This is necessary, in particular, so that the immune system of the mother does not tear off the baby, which in essence is a "foreign body". To prevent this from happening, the protective properties of the body are reduced, so the viral strains that make up vaccines can break through the defense and cause illness.Exceptions to the rules
Despite the theoretical threat, some vaccines are allowed for use during pregnancy, for example a vaccine against influenza or papillomavirus infection. Most of these vaccinations obstetricians-gynecologists do not recommend doing future mothers in the early stages. During the first 12 weeks, all important organs are formed in the child, so acquaintance with the light version of the virus at this stage is highly undesirable. For the same reason, the same clause is found in the instructions to many medications.
Most doctors recommend vaccination to pregnant women only in force majeure. They believe that in other cases, the benefits of vaccines do not justify the inherent risk. There are only 2 situations when vaccination is really necessary. Unconditional reason for emergency vaccination is the threat of infection with rabies, because this disease is fatal. If you are bitten by a familiar dog, you can take it to a veterinarian and test it. Doing this is desirable in the first 24/48 hours after the attack, with the earlier you do it, the better. If you can not catch the dog, you need to go to the hospital, especially if he behaved strangely and attacked you for no reason. The vaccine against rabies is harmless to the child, so it can be done at any time of pregnancy.
The second exception to the rules? epidemic of influenza, but not seasonal annual, but the one that primarily affects pregnant women. It is known, for example, that last winter the H1N1 virus (the so-called "swine flu") affected mainly children and pregnant women aged 20 to 25 years, causing severe pneumonia. The vaccine has not yet been introduced into this practice, and if this virus appears again, doctors are advised to get vaccinated against the usual flu.Future plans
The most dangerous for the baby during the intrauterine development is still the rubella virus. If a woman becomes infected with the disease during pregnancy, especially in the early stages, the consequences can be sad, down to congenital malformations, central nervous system defects and internal organs, loss of vision and hearing. However, during pregnancy, vaccination against rubella can not be carried out. If the infection occurs in the I or II trimester, doctors tell the woman about the possible consequences and leave behind her the right to decide how to proceed. If this happens at a later date, the risk to the child will be minimal.
Protect your future baby from the dangers of a woman can in the event that she plans pregnancy in advance. This practice exists in all developed countries. Vaccination is carried out 6 months before the date of the alleged conception, but before you get vaccinated, it is important to find out if you have had rubella before or not. An unequivocal answer to this question can only be given by a blood test. If you do not have antibodies to the virus, you will be given a vaccine and reminded that within six months you need to be protected.
The second place is occupied by the herpes virus: it is dangerous for an unborn child in the case if the woman has been infected for the first time during pregnancy. But there is no effective vaccination against it yet.Read on this topic:
