Winter Vaccinations During Pregnancy

With winter bringing an increase in flu and other respiratory illnesses in Hungary, understanding vaccination guidelines during pregnancy is crucial to protect both mother and baby. Dr. Erika Bodnár, a pediatrician and lactation consultant at FirstMed, offers practical advice on seasonal immunizations, including recommended vaccines and essential precautions.

What is the vaccination's protective process for babies during pregnancy?

When the mother gets vaccinated during (or just before) pregnancy, the developing baby safely receives necessary antibodies (immunoglobulin IgG) from her through the placenta. This natural process helps build the baby's immune system, providing reassurance that maternal vaccination offers added protection for the newborn.

In the winter season, protecting yourself against common respiratory infections is safe and beneficial. Vaccinations can strengthen your immune system and provide peace of mind during pregnancy.

In the winter season, it is crucial to protect yourself against common respiratory infections when pregnant. Taking vaccinations against these is a key to shielding by enhancing the immune system. 

  • Influenza: Given the changing seasons in Budapest, the flu vaccination is recommended for all pregnant women as early as possible in autumn to protect themselves and their newborns from severe flu complications. 

  • Dtap (diphtheria, tetanus, pertussis): Recommended between weeks 26 and 32 of pregnancy, this vaccine is crucial for safeguarding against whooping cough, which can be particularly severe in newborns.

  • COVID-19: With COVID-19 vaccines available at designated vaccination points and family practitioners in Budapest, it's recommended to protect against the virus's complications at any stage of pregnancy.

  • RSV (Respiratory Syncytial Virus): Following local health authorities' advisories, an RSV vaccine may be recommended for pregnant women in weeks 24-36 (also possible in 30-32 weeks), to protect the newborn from severe RSV infection in its first 6 months, which can be prevalent in Hungary.

Aim to get vaccinated early in the season to build your immunity before the peak of respiratory illnesses. If vaccination is delayed, take extra protective measures to reduce infection risk when vaccinated later in the season.

Always consult your healthcare provider before vaccination to receive personalized guidance, ensuring your safety and peace of mind during pregnancy.

Traveling during the winter months while being pregnant

The winter holiday season often involves traveling to visit family and friends or enjoying leisure activities abroad. However, traveling to certain destinations that require specific vaccinations may pose risks during pregnancy. As a rule of thumb, when pregnant, avoid those countries or regions that require travel vaccinations, or consult a travel medicine specialist if you must travel to ensure safety.

What precautions should pregnant women take when getting vaccinated against respiratory infections in the winter season?

As winter sets in Hungary, the incidence of respiratory diseases is on the rise. Since it takes approximately 2 weeks for the body to develop protective antibodies after vaccination, take extra care to prevent infection if you are vaccinated during this period.

  • Avoid Crowds and Practice Distancing: Minimize your time in crowded areas. When in public, especially indoors or in settings where maintaining distance is difficult, wear a mask to reduce the risk of exposure to respiratory viruses significantly.

  • Maintain Good Hand Hygiene: Wash your hands frequently with soap and water for at least 20 seconds, or use a hand sanitizer containing at least 60% alcohol.

  • Good Ventilation: Frequently ventilate your home, office, and other indoor spaces where you spend a lot of time. This practice helps reduce the risk of being infected.

  • Support Your Immune System: Focus on a healthy lifestyle, including a balanced diet, adequate hydration, and sufficient rest. These practices are crucial for supporting your immune system during this vulnerable period.

  • Schedule Vaccinations Wisely: Only get vaccinated when you are feeling well. Postpone your appointment if you are currently ill or running a fever.

  • Provider Visits: When visiting your healthcare provider, wearing a mask and adhering to hygienic measures is even more critical.

Vaccination for family members, “nest protection”

To create a safer environment for expectant mothers and newborns, it is beneficial for those in close contact with them to be vaccinated as well. Close relatives, friends, and family members should prioritize getting the updated flu shot for the current winter season, as well as the DTaP (diphtheria, tetanus, and pertussis) booster and the chickenpox vaccine, fostering a sense of community responsibility and shared protection.

How to schedule vaccinations while being pregnant?

Being proactive with vaccinations provides the best protection for pregnant mothers and their babies. It is ideal to get vaccinated before conception, preferably in the fall and as early in the season as possible, using the updated flu vaccine. 

However, you are still safe to receive the recommended vaccinations up to the 36th week plus 6 days (i.e., before the 37th week) of pregnancy, and avoid any within 2 weeks of childbirth. Certain vaccines require multiple doses spaced over several months, and if the vaccination series cannot be completed within the recommended timeline, it can be continued during breastfeeding.

What about being vaccinated during breastfeeding?

Getting vaccinated soon after delivery still protects the mother and helps transfer necessary antibodies to the baby through breastfeeding. If you couldn't receive the recommended vaccines before or during your pregnancy, it's safe to get them while you're breastfeeding. During this time, both mothers and their babies develop their own immunity. However, be aware that infants are more vulnerable, so take extra care and follow the precautions mentioned above in the winter season to protect your newborn. Meanwhile, babies also start receiving their own vaccinations to help shield them from serious childhood diseases.

Summary

Pregnancy is a highly vulnerable period for mothers regarding respiratory illnesses, and after birth, for the baby. Certain vaccinations, such as flu, COVID, RSV (respiratory syncytial virus), and pertussis (whooping cough), are not only safe but highly recommended during pregnancy, especially in the winter season, to protect both the mother and her newborn. Additionally, taking precautions and maintaining good hygiene is even more crucial during pregnancy in the winter months.

You can receive these recommended vaccinations at various local public and private healthcare facilities, including FirstMed in Budapest, which offers comprehensive English-speaking prenatal and pediatric care. These services include vaccination consultations tailored to the specific needs of expectant mothers and newborns.
