Covid-19 vaccine Can it affect pregnancy or lactation?

The campaign of SARS-CoV-2 virus vaccination, responsible for Covid-19. And while health workers and the elderly are already getting vaccinated, new questions are emerging about who should get vaccinated. In a special way attention is paid to pregnant and lactating women, for those of us who cannot say that there is data capable of providing definitive information on the risks or not of this vaccine, so it will not hurt do a brief review of what is known to date and what the competent bodies have expressed.

Covid-19 vaccine Can it affect pregnancy or lactation?

At the end of last December 2020, it was when the Spanish population began to be vaccinated. At the moment doses of the Pfizer vaccine are being applied of which according to previous information, was not sufficiently tested on specific cases such as pregnant and lactating women.

However in any case, studies made so far have not shown or suggested biological mechanisms that may associate mRNA vaccines such as that of Pfizer (and also that of Moderna that will soon begin to be applied in Spain), with adverse effects on pregnancy and laboratory evidence in animals suggests the absence of risk of vaccination, so once vaccination begins in all sectors of the population, it will depend on each case and for pregnant and lactating women who wish to be vaccinated, you should consult your doctor to decide whether or not to get vaccinated.

Anyway we can as we say, hgive a review on what is better or what not both in case of pregnancy and in case of breastfeeding, although Covid-19 can also be a risk for these women.

Can I get vaccinated if I am pregnant?

As we say so much the WHO, as an international organization as well as the Ministry of Health and the European Medicines Agency, recommend that before vaccinating a pregnant woman it should be discussed “case by case” with the health professional, so that he or she can assess the possible benefits or risks individually.

On the other hand, the Spanish Agency for Medicines and Health Products (AEMPS) answer back in a question and answer document about Comirnaty which is the mRNA vaccine against COVID-19 developed by Pfizer / BioNtech that laboratory studies in animal models have not provided negative results, although these should be taken with caution although the information on the risks in pregnancy is currently limited, while it turns out non-existent in the case of breastfeeding.

In any case, in the same document it is explained that the absence of evidence in both groups is something “usual” since “Clinical experimentation in these cases begins when the efficacy and safety have already been confirmed in other groups.”

Regarding the Autonomous communities, some of them have their own guidelines, although all agree that pregnant women will not be vaccinated at first and in the case of doing so, it will depend on each case, and that these must also be evaluated by a health professional.

Despite this, it is already known for example that Catalonia strongly recommends Do not recommend pregnant women, while in Madrid you can only vaccinate if the woman belongs to a risk group (and always under a previous evaluation of the doctor). It is also further known that Andalusia and Asturias, the vaccine will be “studied” only in “special cases” when there is “high community transmission, unavoidable risk of exposure (such as health workers) or high risk of serious disease.”

In this way, we can conclude that the vaccine against Covid-19 is not considered a “priority” in pregnant women since, in addition, in most cases of pregnant women who have been victims of coronavirus, the disease has passed asymptomatically. Not so in complicated cases or if the woman belongs to a risk group.

What to do if I am pregnant and I belong to a risk group?

As we have already said, it will be a matter of analyzing each case in detail to know the benefits or risks that the vaccine may have with respect to pregnancy if it is a woman who belongs to a risk group, although there are statements from the American Committee on Practices of Immunization (ACIP / CDC), which comment on this: «Pregnant women and the ones breastfeed their children and who belong to the established risk groups can choose between delaying the vaccination until more information is available, or agreeing to be vaccinated ». Considering also that the vaccine is not expected to pose a risk or danger despite the fact that there is still not much information, something that is also expressed by, among others, the American College of Obstetrics and Gynecology and the Academy of Breastfeeding Medicine of the USA. USA

Can I get vaccinated if I am breastfeeding?

With women who are breastfeeding their babies, the case is practically the same as what happens with pregnant women. In fact both the Ministry of Health, as well as the Spanish Medicines Agency, they do not consider the vaccine a “risk”, although they make the above mentioned very clear:

“The decision to use the vaccine in women pregnant or during lactation maternal should be done with the assessment of a healthcare professional to individually assess the benefits and risks according to each case.

Regarding what the Autonomous Communities have announced, Asturias and Andalusia do not rule out vaccinating nursing mothers as long as they have an rhigh risk against COVID, but Catalonia, on the other hand, advises against vaccination at all times both during pregnancy and lactation. As for the Community of Madrid have not issued any recommendation till the date.

On the other hand, the specialized website e-Lactancia, rcarried out by lactation professionals, they do not consider that there are risks with the vaccine against Covid-19, although they consider that although there are no studies that prove it (since lactating women were excluded from all the trials carried out), they consider that it is completely “unlikely” that the components of the vaccine pass into breast milk, if the mother is vaccinated, and if so, they would become “digested in the infant’s intestine” therefore, «It seems reasonable to think that if the virus is compatible with breastfeeding, the vaccine will be more so since it does not even contain the live virus ».

He also points out that because of this Lactating women should not be excluded from the vaccine when they are part of a risk group.

What to do if we are nursing mothers and from a risk group?

In this way, if you belong to a risk group and are also breastfeeding, the woman should have the option of the vaccine, although as in previous cases, it must be evaluated individually and always under the guidelines of the healthcare professional.

What if I am planning pregnancy? Can i get vaccinated

It was news recently that some health workers and caregivers who work in nursing homes had decided not to get vaccinated to avoid risks in the event of becoming pregnant during pregnancy, despite the fact that at the moment there would be no evident proof that this is the case. Anyway, some communities do not advise against not administering the vaccine, but specify something very specific. In fact, Navarra, Catalonia and Andalusia recommend that two months elapse between the administration of the second dose of the vaccine and the onset of pregnancy, while The Vaccine Advisory Committee of the Spanish Association of Pediatrics recommends waiting at least one month between the administration of the vaccine and the beginning of pregnancy.
