Q&A: Vaccinations okay during pregnancy?

My last period was more than seven weeks ago. I've taken multiple tests, including a blood test and all have been negative. With my son, I did the same thing and couldn't get a positive test until I was 9 weeks. I have vaccinations for school that I am due for and need to know whether or not I should take them. What do you suggest? -- Mrs.Mandy

Depending on which test you use, you may be able to tell if you are pregnant in as little as a week after ovulation. A blood test is the earliest test to show a positive result (7-11 days after ovulation), while some home pregnancy test kits can test positive at the time of your missed period (14 days after ovulation) in up to 95% of pregnant women. If your last period was more than seven weeks ago and all tests since then have been negative, then it is unlikely that you are pregnant. But, it is difficult to say for sure without knowing the length of your usual cycles (the number of days from the first day of one period to the first day of the next).

With this information, if you still think that you might be pregnant, you should ask specifically which vaccinations you need. Some vaccinations (e.g. the flu shot) are safe during all trimesters of pregnancy. In fact, it is recommended that all pregnant women and women who plan on being pregnant during flu season (October through May) receive the inactivated flu vaccination. Other vaccinations such as the rubella vaccination should not be given during pregnancy. The rubella vaccination is what we call a live attenuated vaccine, meaning it consists of live but weakened virus. If you receive this vaccination during pregnancy, it can theoretically cross the placenta and affect the fetus although there have been no reports of adverse fetal effect in women who were inadvertently vaccinated during the first trimester. For more information, visit the CDC’s website. It’s a great resource with information about vaccination during pregnancy.

I had a very similar situation, but in my case, I did not do a blood test - just the urine tests. I'm not sure if blood tests are much more accurate than urine tests, I hear from doctors that urine tests are fairly accurate. I ended up being pregnant and was fighting tooth and nail to put off getting any vaccinations because I don't believe in them in the first place, but I am willing to get them myself, but not my teeny tiny undeveloped embryo. They're pumped with chemicals, are you kidding? Anyway, I ended up being pregnant and was able to just show proof of the pregnancy and that was fine - you shouldn't have to get any vaccinations even if they're considered safe. But, if they are considered safe and you want to get them, then they should be willing to administer them. They won't do the rubella vaccination unless you have a note from your obstetrician.

Follow the advice of the expert. Many vaccines are safe during pregnancy but some do carry a potential risk. There's a whooping cough outbreak here where I live and I hadn't had a booster for that one. I was able to get a booster in my doctor's office during a prenatal visit. If you are pregnant that's a pretty important one to be vaccinated against. Adults can carry the disease and only have a mild cough then give it to a new born who can easily become hospitalized or die from it. Very scary stuff. Oh and when someone says not to use something because it's "pumped with chemicals" ignore them. They clearly don't know what the definition of "chemical" is.

Don't take them! All women do not have a positive test even after 8 weeks......when they did my first blood test, it came out negative even though I was already pregnant. You could very well be pregnant...I missed my period for two months and was still getiting negative tests, even though I was pregnant.

And what kind of experience do you have with vaccines that you think you can make your demeaning comments on them @akennonf? They are pumped with chemicals. YOU need to do your research or not contribute to the conversation.
