The Spanish Society of Gynecology and Obstetrics (SEGO) together with eight other scientific societies have updated a document of advice on vaccination against Covid in pregnant women or for those who are planning to become pregnant.
In it, they recommend a third booster dose of the vaccine to maintain protection. If the pregnant woman received an mRNA vaccine from Moderna or Pfizer, it is recommended to administer the booster dose from six months after the full vaccination, and if she has received AstraZéneca or Janssen, from three months .
In the statement issued, the companies state that “There is no data that suggests that the risk of the third dose is different from that of the previous ones, neither for the mother nor for the fetus,” the document states, so the recommendation of the third dose is maintained in the same terms as for the previous two, remembering that “pregnant women have a higher risk of severe COVID-19, admission to the ICU, need for mechanical ventilation and women than the general population, although the absolute risk stay low . “
From week 14 of gestation
SEGO, together with the rest of the scientific societies participating in the Facme document, recommends that the administration of this booster dose be carried out preferably from week 14 of gestation , once the period of greatest theoretical risk for the fetus due to the vaccine and in order to have achieved full vaccination before reaching the period of maximum risk of complications from natural infection.
However, and given that there is no contraindication for vaccination at any time during pregnancy, the document establishes that the administration of the third dose in the first trimester can be considered individually in pregnant women with high risk of exposure or presence of comorbidity, and where it is therefore estimated that the benefit outweighs the risks .
In the event that the first doses of the vaccine were from AstraZeneca or Janssen, it is also recommended to use the mRNA vaccine for the booster dose .
For pregnant women who have not received any doses so far, the use of mRNA vaccines is also recommended, regardless of the age of the woman.
Facilitate vaccination in pregnant women
In light of the available scientific evidence, SEGO understands that the Ministry of Health will include the recommendation of the third dose to pregnant women in its next update of the vaccination strategy. Especially, taking into account that a third dose is being considered for those over 40 years of age.
It also asks the administrations to promote specific vaccination points for pregnant women around the services of Hospital Gynecology and Obstetrics and consultation of midwives in health centers where the corresponding individualized assessment can be carried out. It is requested that the administration of vaccination to pregnant women be facilitated from the second trimester in the event of any contact with the health system.
