Does The Covid Vaccine Affect Fertility Cdc

Does The Covid Vaccine Affect Fertility

Ask a Doctor: Do the COVID-19 vaccines affect fertility?

Short answer: No.

Morris said that despite much widespread misinformation, there are no links to fertility issues.

According to the CDC, there is no evidence at this time that antibodies made following COVID-19 vaccination or that vaccine ingredients would cause any problems with becoming pregnant now or in the future.

Vaccines And Period Changes

To date, none of the COVID-19 vaccine manufacturers list any issues pertinent to menstrual health as a side effect.

However, Dr. Male says more than 30,000 people reported menstrual cycle changes following vaccination to the MHRA. She explains that most people who report experiencing changes to their menstrual cycle say things typically return to normal by the next cycle. Importantly, there is no evidence that COVID-19 vaccination adversely affects fertility.

The author says that research is needed to determine a definitive link between the two and what is triggering that response in some people.

If there is a connection, it is likely to be a result of the immune response to vaccination rather than a specific vaccine component, Dr. Male writes.

Stress can disrupt the menstrual cycle and cause cycles to vary or even stop altogether. The immune response created by vaccines can cause this type of stress reaction.

According to Dr. Male, the lack of research on the effects of COVID-19 vaccines on periods is due to the relatively low occurrence of these reports.

Euronews: What Is The Impact On Periods

On blogs and across social media, women have shared their stories of a change to their menstrual cycle, such as changes to the regularity and volume .

A study said it is unclear whether apparent changes are due to COVID-19 infection/illness itself, or other pandemic-related factors like increased psychological stress and changes in health behaviours.

The study also said it was also unclear to what degree current findings are explained by reporting bias, recall bias, selection bias and confounding factors, adding, more research is needed.

But there have been no negative effects on periods reported.

Dr Mosina: Many women participated in clinical trials which did not identify any negative effects of vaccination on the menstruation cycle.

Additional evidence confirming safety of vaccines with regards to menstruation came from national and global vaccine safety monitoring systems after vaccination programmes were rolled-out.

What About Any Long

Both the Pfizer and Moderna vaccines are mRNA COVID-19 vaccines. They work by giving the body a code to help the body recognize the “spike protein” in the structure of the COVID-19 virus and make antibodies against it.

The vaccine itself is destroyed within a few days after injection, but the antibodies remain to help fight off future infection, the doctors explain.

“When we look at long-term risks of the vaccine, we don’t see any, because of how these vaccines work,” Kramer said. “At this point, the only long-term effect of a vaccine that we know is survival you are highly unlikely to have complications from COVID or die.”

Pregnancy Losses Reported To Vaers Lead To Demand To Halt Covid Vaccine


We have seen 100 pregnancy losses reported in VAERS as of April 9th. And there have been reports of impaired spermatogenesis and placental findings from both the natural infection, vaccinated, and syncytin knockout animal models that have similar placental pathology, implicating a syncytin-mediated role in these outcomes.

Additionally, we have heard of multiple reports of menses irregularities in those vaccinated. These must be investigated.

We simply cannot put these in our children who are at .002% risk for Covid mortality, if infected, or any more of the child-bearing age population without thoroughly investigating this matter.

, we could potentially sterilize an entire generation. Speculation that this will not occur and a few anecdotal reports of pregnancies within the trial are not sufficient proof that this is not impacting on a population-wide scale.

Mrna Vaccines Are New But Not Unknown

Researchers have been studying and working with mRNA vaccines for decades. Interest has grown in these vaccines because they can be developed in a laboratory using readily available materials. This means the process can be standardized and scaled up, making vaccine development faster than traditional methods of making vaccines.

mRNA vaccines have been studied before for flu, Zika, rabies, and cytomegalovirus . As soon as the necessary information about the virus that causes COVID-19 was available, scientists began designing the mRNA instructions for cells to build the unique spike protein into an mRNA vaccine.

Future mRNA vaccine technology may allow for one vaccine to provide protection for multiple diseases, thus decreasing the number of shots needed for protection against common vaccine-preventable diseases.

Beyond vaccines, cancer research has used mRNA to trigger the immune system to target specific cancer cells.

Molecular Biologist And Toxicologist Calls To Halt Covid Vaccine

Hi, my name is Dr. Janci Chunn Lindsay. I hold a doctorate in biochemistry and molecular biology from the University of Texas, and have over 30 years of scientific experience, primarily in toxicology and mechanistic biology.

In the mid-1990s, I aided the development of a temporary human contraceptive vaccine which ended up causing unintended autoimmune ovarian destruction and sterility in animal test models. Despite efforts against this and sequence analyses that did not predict this.

I strongly feel that all the gene therapy vaccines must be halted immediately due to safety concerns on several fronts.

Are Pregnant Women At A Higher

The CDC noted that pregnant people who contract COVID-19 “have an increased risk of severe illness,” including the risk of an infection that could lead to ICU admission, mechanical ventilation, and possibly death. Pregnant people with COVID-19 could also face an increased risk of adverse pregnancy outcomes, such as preterm birth, the agency added.

According to preliminary findings of a study from the National Institutes of Health, pregnant women who experienced severe symptoms of COVID-19 had a higher risk of complications during and after pregnancy.

“Compared to nonpregnant women who have the same health and age, a COVID-infected woman is about 1.3 to 1.4 times more likely to end up in the hospital when she’s pregnant,” Dr. Regan Theiler, a Mayo Clinic obstetrician, said in a statement.

On the other hand, the University of Chicago Medicine reports that for some people vaccinated late in their pregnancy, “it is likely that the antibodies your body produces in response to the vaccine will be passed to the fetus through the placenta and may provide some protection against COVID-19, the same way a flu vaccine can help protect your baby against the flu.”

Should I Get Vaccinated If I’ve Already Been Pregnant

Does the COVID-19 vaccine affect fertility?

Short answer: Yes.

People who have been recently pregnant which the CDC defines as at least 42 days since the end of a pregnancy are at risk for developing severe COVID-19 illness.

Babies under 1 year old might be at higher risk of severe illness with COVID than older children, according to the Mayo Clinic. This is likely due to their immature immune systems and smaller airways, which make them more likely to develop breathing issues with respiratory virus infections.

For these reasons, it is recommended that everyone who lives with or otherwise interacts regularly with recently pregnant people and newborns should get vaccinated against COVID-19.

Before Pregnancy And For Fertility

Research studies have found that COVID-19 vaccines:

  • Do not cause any fertility problems in men or women.
  • Do not cause any problems with becoming pregnant.

Data from v-safe and data directly from eight U.S. health care systems show that COVID-19 vaccines do not prevent people from becoming pregnant. This was also confirmed by an in vitro fertilization study, which showed people who had been vaccinated against COVID-19 were just as likely to get pregnant as people who had not been vaccinated or recently had COVID-19.

A study comparing sperm before and after vaccination with an mRNA COVID-19 vaccine found that vaccination did not affect how much sperm men had or how it moved. Currently, evidence shows that vaccines, including COVID-19 vaccines, do not cause male fertility problems.

Reports claiming that COVID-19 vaccines cause infertility are unfounded. Learn a little more about the science below.

A Closer Look At How Covid

COVID-19 mRNA vaccines give instructions for our cells to make a harmless piece of what is called the spike protein. The spike protein is found on the surface of the virus that causes COVID-19.

  • First, COVID-19 mRNA vaccines are given in the upper arm muscle. Once the instructions are inside the muscle cells, the cells use them to make the protein piece. After the protein piece is made, the cell breaks down the instructions and gets rid of them.
  • Next, the cell displays the protein piece on its surface. Our immune systems recognize that the protein doesnt belong there and begin building an immune response and making antibodies, like what happens in natural infection against COVID-19.
  • At the end of the process, our bodies have learned how to protect against future infection. The benefit of mRNA vaccines, like all vaccines, is those vaccinated gain this protection without ever having to risk the serious consequences of getting sick with COVID-19.

    Myth: If Ive Already Had Covid

    FACT: People who have gotten sick with COVID-19 may still benefit from getting vaccinated. Due to the severe health risks associated with COVID-19 and the fact that re-infection with COVID-19 is possible, people may be advised to get a COVID-19 vaccine even if they have been sick with COVID-19 before.

    There is not enough information currently available to say if or for how long people are protected from getting COVID-19 after they have had it . Early evidence suggests natural immunity from COVID-19 may not last very long, but more studies are needed to better understand this. Several subjects in the Pfizer trial who were previously infected got vaccinated without ill effects. Some scientists believe the vaccine offers better protection for coronavirus than natural infection.

    People Who Are Pregnant


    COVID-19 vaccination is recommended for all people 12 years and older, including people who are pregnant. If you are pregnant, you might want to have a conversation with your healthcare provider about COVID-19 vaccination. While such a conversation might be helpful, it is not required before vaccination. You can receive a COVID-19 vaccine without any additional documentation from your healthcare provider.

    CDC recommendations align with those from professional medical organizations serving people who are pregnant, including the American College of Obstetricians and Gynecologistsexternal icon and the Society for Maternal Fetal Medicinepdf iconexternal icon.

    If you got pregnant after receiving your first shot of a COVID-19 vaccine that requires two doses , you should get your second shot to get as much protection as possible. If you experience fever following vaccination, you should take acetaminophen because feverfor any reasonhas been associated with adverse pregnancy outcomes.

    Will Breastfeeding Pass Immunity On To The Baby

    Multiple studies done over the past year show that COVID-19 vaccines generate an immune response and an increase in antibodies which are found in breast milk. This supply of maternal antibodies in breast milk may provide infants protection from the illness. As with other vaccinations, using the power of passive immunity to protect newborns is shown to be an effective way of preventing disease in newborns.

    We believe that in the vast majority of cases, the benefits outweigh the risks, and the vaccine is much safer than contracting COVID-19.

    Are There Any Guidelines For Timing To Receive The Vaccine In Pregnancy

    Dr. Zaltz: The only consideration about timing relates to other vaccines, like the flu shot and Tdap that are routinely recommended during pregnancy. If you choose to receive the COVID-19 vaccine during pregnancy or the postpartum period, the CDC recommends scheduling it at least 14 days before or 14 days after any other vaccination. Please talk to your health provider about the best timing for the COVID-19 vaccine.

    Repeating Information Does Not Make It So: Doctors Say Covid Vaccines Do Not Affect Fertility

    Though information to the contrary persists, doctors say there is no evidence linking COVID-19 vaccines to infertility, in men or women.

    It has been proven that the vaccines have no effect on the ability to conceive children, said Dr. Michael Tsimis, maternal-fetal medicine specialist with Spectrum Health, based in Grand Rapids.

    The vaccine has not only shown to benefit outcomes and reduce hospitalizations for expectant mothers but also for women looking to get pregnant in the future, the fertility is unchanged.

    Doctors have repeatedly noted this, but information persists. An Indiana University survey conducted in June found about 25% of nearly 700 participants believed it was definitely or probably true that vaccines affect fertility.

    An ESPN reporter in September walked away from her role because she said she was trying to conceive a second child and did not wish to be vaccinated.

    Rapper and singer Nicki Minaj got worldwide attention in recent weeks for tweeting about her cousins friend, impotent since immunization. It even solicited a response from the nations top infectious disease doctor, who debunked her statement, and Englands prime minister.

    Im not going to have her put that experimental nonsense into her body.

    He understands the hesitancy of someone who have had trouble conceiving.

    Is Pregnancy A Risk Factor For Covid

    Covid Vaccine Side Effects Uk Fertility

    Short answer: Yes.

    Pregnancy increases someone’s risk of severe illness when it comes to the coronavirus. Being pregnant slightly lowers the immune response, UMMC maternal-fetal medicine specialist Michelle Owens said.

    Early on in the pandemic, Morris said she would see COVID-positive patients in their third trimester with mild symptoms. However, with the highly infectious delta variant that began sweeping the state in July, pregnant people are being admitted earlier in their pregnancies. Morris said recent COVID infections in pregnant people is nothing like she has seen before.

    According to the CDC, pregnant people with COVID are also at increased risk for preterm birth, which it defines as delivering the baby earlier than 37 weeks.

    State Health Officer Thomas Dobbs said 72 COVID-positive mothers in Mississippi have miscarried after 20 weeks gestation. This is double the normal rate, he said.

    Monitoring Data Shows Vaccines Cause Miscarriages

    Some posts have highlighted miscarriages reported to vaccine-monitoring schemes, including the Medicines and Healthcare products Regulatory Agency Yellow Card scheme in the UK and the Vaccine Adverse Event Reporting System in the US.

    Anyone can report symptoms or health conditions they experience after being vaccinated. Not everyone will choose to report, so this is a self-selecting database.

    There were indeed miscarriages reported in these databases – they are unfortunately common events – but this does not mean the jab caused them.

    They are not so good at monitoring side-effects that are common in the population – such as changes to periods, miscarriages and heart problems. Seeing them in the data doesn’t necessarily raise these red flags because you’d expect to see them anyway, vaccine or not.

    It’s only if we start getting many more miscarriages than are seen in unvaccinated people that this data would prompt an investigation – and that’s not been the case so far.

    Some people have also shared graphs showing a big rise in the overall number of people reporting their experiences to these schemes compared with previous years, for other vaccines and drugs.
