RSV Vaccine during Pregnancy | The Evidence

We all want to keep our newborn babies safe. When looking at common illnesses, RSV is a frequent concern amongst new parents. The latest recommendation? Recieve the RSV Vaccine during pregnancy. If your doctor has made this suggestion you may be curious how it works. Let’s take a look at what RSV is and what you can do before your baby is even born to protect them from it.

What Is Respiratory Syncytial Virus (RSV)?

Respiratory syncytial virus (RSV) is a leading cause of hospitalization in infants, responsible for 58,000–80,000 annual hospitalizations in children under 5 in the U.S. Babies under 6 months are especially vulnerable, as RSV can lead to severe lung infections like bronchiolitis and pneumonia. We’ve done a deep dive on the specifics of RSV in babies, you can check that out here!

It’s important to remember that while RSV is dangerous for infants and the immunocompromised, it can present as a common cold in healthy individuals. This means even if someone’s only symptom is a runny nose, they could spread the illness.

How does getting the RSV vaccine during pregnancy work?

The Abrysvo vaccine, approved by the FDA and recommended by the CDC, is given to pregnant individuals between 32 and 36 weeks of gestation. It works by transferring protective antibodies to the fetus, providing passive immunity that shields infants during their most vulnerable early months.

Is it safe and effective?

Yes! Clinical trials show impressive results:

81.8% efficacy against severe RSV within the first 90 days of life.
69.4% efficacy through 6 months of age.

Safety data from over 7,000 participants revealed no significant risks to pregnant individuals or babies. The most commonly seen side effects are mild such as injection site pain or fatigue and they were reported to be short-lived.

What else should I know about the RSV Vaccine during Pregnancy?

Timing: CDC recommends vaccination at 32–36 weeks, ideally before RSV season (typically fall/winter).

Who should get it? Most pregnancies without contraindications. This could be something such as an allergy to the vaccine’s components.

Alternative option: For those unable to receive the vaccine, there is an option that can be given to infants post-birth.

The American Academy of Pediatrics (AAP) and World Health Organization (WHO) endorse RSV vaccination during pregnancy as a safe, effective way to reduce infant complications due to RSV.

Take Action

The most important thing you can do when considering healthcare decisions is to talk to your trusted healthcare provider. You can practice using the BRAIN acronym during your prenatal visit by asking the following questions:

Benefits – What are the benefits of recieving the RSV vaccine during pregnancy?
Risks – What are the known risks? What are the risks of RSV to a newborn?
Alternatives – What alternatives do I have?
Intuition – What am I feeling now that I know the science-based answers to my questions?
Nothing – What happens if I do nothing about RSV?

By vaccinating during pregnancy, you’re offering your baby a strong first defense against a potentially serious illness.

Install a Car Seat Safely: How To

Childbirth Education, Newborn care

Installing a car seat safely is one of the most important things to do before baby arrives. In fact, you can’t leave the hospital without a car seat. Choosing and installing a car seat that best fits your vehicle and lifestyle can seem daunting. That’s why our own Child Passenger Safety Technician (CPST) is here to help. Here are six steps to ensure your baby’s car seat is safely installed.

Be Prepared when Installing a Car Seat Safely

If you are a first-time parent, you’ve probably never installed a car seat before. And even if you have other children, you may not be familiar with your new car seat’s installation procedures. To install your car seat safely, read both the entirety of your car seat manual and the portions of your vehicle owner’s manual that pertains to child restraints. We recommend that you install your seat by your 36th week of pregnancy.

Accessories Can Be Dangerous

It might be tempting to use aftermarket accessories for your car seat or car. Don’t. Use only manufactured approved items that come in the box with your car seat (infant inserts, strap covers, etc.). This includes cozy winter inserts like the J.J. Cole Bundle Me, which are not approved for use in car seats.

Don’t Leave Baby in the Car Seat

Avoid keeping baby in the car seat more than absolutely necessary. A car seat is designed to keep baby snug and safe, but limits baby’s movement. Even if baby fell asleep in the car seat, consider babywearing or a stroller with a bassinet instead.

Ensure Proper Use of the Car Seat

Straps should come through the slot just below baby’s shoulders, be snug enough that you can not pinch any slack at the collarbone or hips and chest clip should be even with baby’s armpits. Never loosen car seat straps or unbuckle the chest clip or crotch buckle unless you are removing the baby from the seat.

Consult a Child Passenger Safety Technician to Install the Car Seat Safely

Before baby arrives, schedule an appointment with a certified Child Passenger Safety Technician (CPST). A CPST is qualified and trained to make sure that your car seat is installed correctly and can help you install a baby car seat safely.

Am I actually going into labor?

Pregnancy

One of the most searched topics during pregnancy? “Am I actually going into labor?”

Although the conventional knowledge says that pregnancy lasts nine months (which would be 36 weeks), most babies are actually born between 38 and 42 weeks. This means that you can think of your due date as more of a “due month” rather than a specific date. In fact, less than 5% of babies are born on their due date. This date range can present a problem, though: how do you know if you are actually ready to meet your baby? Here are four surefire ways to know if you are going into labor.

You’re experiencing certain physical and emotional changes.

There are specific physical and emotional changes we hear from clients that make your doula double check her birth bag and put her running shoes by the door! We often see a change in emotions and becoming more sensitive. Bursts of nesting energy and new or unusual cravings can also signal your body is getting ready to give birth. Physical changes may also occur.

These may include:

feeling “crampy” or having backaches
increased vaginal discharge
loss of mucus plug (especially blood-tinged mucus)
softer, more frequent bowel movements.

Be in tune with your body and emotions, and communicate those changes with your care providers as you get closer to your due month.

You’re having uterine contractions.

Uterine contractions are the first sign of going into labor for most people. But how do you know the difference between uterine contractions and Braxton Hicks or false labor contractions? Uterine contractions are regular and consistent; they get steadily closer, stronger, longer and do not lessen with rest, movement, eating or drinking. You may have contractions before you are in labor. But if they are not causing your cervix to change, you are not in labor. See our blog post on latent labor for more on those contractions.

Your water breaks.

You’ve seen it in movies and on tv shows: water spills on the floor and the character suddenly knows their baby is coming. In reality, only occasionally does your water break ahead of contractions. Typically the other signs we’ve outlined will happen for hours or even days prior to your water breaking. Ir this is your first sign, the vast majority of people will experience contractions that follow within 12-24 hours.

Your cervix is not a crystal ball and it can’t tell you if labor is imminent.

Cervical exams are not necessarily an indication of when labor will begin. There are a number of cervical changes that have to take place ahead of dilation, the number measured in centimeters that we all associate with how close the baby is to being born.

Your cervix will go through these changes:

shift forward to align with the birth canal
soften or ripen
thin (or efface)
The final step is dilation.

These changes may be evaluated by your care provider during a cervical exam once you head to the hospital in order to determine if you are in labor.
