Is Measles Dangerous If You Are Pregnant?

While folks often try and make it seem like measles is a common childhood illness, we know that it can be dangerous.

“One of the patients was a 20-year-old pregnant woman who had rash onset on January 5 following exposure to her 12-year-old brother. After delivering a healthy baby on January 6, the mother developed severe pneumonia that was followed by respiratory arrest. She was resuscitated and transferred to an intensive care unit in a larger hospital nearby in Tennessee.”

Rarely do people who have really had measles describe it as just a fever and a rash. They remember that it was called a harmless killer for a reason.

Is Measles Dangerous If You Are Pregnant?

And there are some situations in which measles can be especially dangerous, including if you get sick when you are very young, very old, or have immune system problems.

Pregnant women should be screened for measles immunity.

And what if you are pregnant when you get measles?

“The Health Department announced today that the number of measles cases has grown to 390, including two pregnant women diagnosed with the infection, one diagnosed in mid-April.”

The Number of Measles Cases Grows to 390

If you are pregnant and you are exposed to someone with measles, you can get IVIG post-exposure prophylaxis to prevent you from actually getting measles, but this typically only works if given within six days of the exposure.

“To date, studies have not identified an increased risk for birth defects when pregnant women get the measles during pregnancy. However, studies suggest that measles infection is associated with an increased risk for miscarriage, stillbirth, prematurity and the baby being born with a measles infection.”

When Measles Strike, It’s Not The Happiest Place On Earth For Pregnant Women

Unlike a rubella infection during pregnancy, a measles infection is not thought to cause birth defects. Tragically, it can, like rubella, lead to an increased risk for having a miscarriage.

“Infants who develop congenital measles are at increased risk for mortality and for subacute sclerosing panencephalitis, which is more common when measles is diagnosed in infancy. In addition, subacute sclerosing panencephalitis in newborns infected with measles either congenitally or shortly after birth appears to be more severe, with a shorter latency and rapidly progressive course.”

And if the mother gets measles very late in her pregnancy, it can also lead to a case of congenital measles, or a baby being born with an active measles infection.

“In 52% of cases, measles was likely acquired from a relative. Complications included pneumonia in one child; two pregnant women required hospitalization, including one who miscarried.”

Don’t take the risk that you might get measles while you are pregnant.

Make sure you are vaccinated and protected before you ever start thinking about getting pregnant, as pregnancy is a contraindication to getting the MMR vaccine. And you should wait at least 4 weeks after getting vaccinated before getting pregnant.

Did the FDA Admit That the Government Is Recommending Untested, Unlicensed Vaccines for Pregnant Women?

Have you heard?

There is a new bombshell from anti-vaccine folks!

It turns out, they say, that the FDA has admitted that the government is recommending untested, unlicensed vaccines for pregnant women.

Is that true?

Did the FDA Admit That the Government Is Recommending Untested, Unlicensed Vaccines for Pregnant Women?

Of course not!

Their evidence?

A response to a Freedom of Information Act request for vaccines that don’t exist. That’s right, neither Tdap nor flu vaccines are currently FDA approved for use by pregnant women.

Of course, that doesn’t mean that Tdap and flu vaccines aren’t recommended for use by pregnant women.

Wait, why the difference?

Why are pregnant women being given a vaccine that isn’t formally FDA approved for their use?

Well, vaccine manufacturers have to seek FDA approval for their products. The FDA doesn’t just up and approve new products or give them new indications. And none have ever sought approval in pregnancy.

But that doesn’t keep health experts from making off-label recommendations, such as getting a flu vaccine when you are pregnant.

“In prelicensure evaluations, the safety of administering a booster dose of Tdap to pregnant women was not studied. Because information on use of Tdap in pregnant women was lacking, both manufacturers of Tdap established pregnancy registries to collect information and pregnancy outcomes from pregnant women vaccinated with Tdap. Data on the safety of administering Tdap to pregnant women are now available.”

As important as FDA approval is a recommendation from the Advisory Committee on Immunization Practices (ACIP). In fact, even after a vaccine gets approved by the FDA, it still has to get a recommendation from the ACIP before it gets on the immunization schedule and is used routinely!

“Flu shots have been given to millions of pregnant women over many years with a good safety record. There is a large body of scientific studies that supports the safety of flu vaccine in pregnant women and their babies.”

Flu Vaccine Safety and Pregnancy

Getting a flu vaccine during pregnancy is a recommendation that has been evolving since 1983. It was known to be safe then, and we are even more confident that it is safe now.

A Tdap shot has been recommended since 2011, although it was first suggested in 2008 that pregnancy was not a contraindication for receiving Tdap.

How do we know these vaccines are safe during pregnancy?

The Vaccine Safety Datalink has published more than 14 studies “related to pregnancy and vaccination during pregnancy” and has used “data to study the health of children born to women who were vaccinated during pregnancy.”

Despite what Robert F. Kennedy, Jr and his ironically named Children’s Health Defense organization might think, Tdap and flu shots in pregnancy have been well studied and have been found to be safe.

Ignoring all of the above studies, Kennedy highlights a few that he thinks found problems with flu shots in pregnancy, including one that showed “a suggestion of increased ASD risk among children whose mothers received an influenza vaccination in their first trimester,” a suggestion that was not statistically significant and which was not found in the other trimesters. And another that found an increased risk of spontaneous abortion in women who had also received a flu shot in the previous season, a safety signal that has never been seen before and which continues to be investigated.

Not surprisingly, his latest bombshell is landing with as big of a thud as his HHS lawsuit, as have most of his statements these days…

“CHD’s Chairman Robert F. Kennedy, Jr. notes that most flu shots given to pregnant women still contain a mercury-based preservative thimerosal.”

FDA Admits That Government Is Recommending Untested, Unlicensed Vaccines for Pregnant Women

Has Kennedy missed the fact that 80% of flu vaccines are now thimerosal free? It makes you wonder how he defines the word “most?”

“Thimerosal is acknowledged by Proposition 65 in California as a reproductive toxicant and exposure during pregnancy can cause learning and behavioral problems. Tdap contains aluminum, which FDA regulates as a toxin in parenteral nutrition but not in vaccines.”

FDA Admits That Government Is Recommending Untested, Unlicensed Vaccines for Pregnant Women

And what is he concerned about in thimerosal-free flu shots which also don’t contain aluminum? Are those okay in his book?

Mostly, after several flu seasons in which so many people have died, you have to wonder what his goal is here. Does Robert F. Kennedy, Jr. expect folks to skip getting a flu shot when they are pregnant and instead risk getting the flu? Should they skip their Tdap shot and risk their baby dying of whooping cough?

Or should they just stop listening to this type of anti-vaccine propaganda?
