Research published last week tracked nearly 4,000 U.S. women through six menstrual cycles and on average, the next period after a shot started about a day later than usual. 

The key word there is "average". Although on average there is no significant change according to the app, a number of women have reported longer and/or more intense menses. This is consistent with the Pfizer data showing the vaccine nanoparticles accumulating on the ovaries. Just because most women haven't noticed any differences doesn't mean there is no damage. Time will tell.

-4 ( +8 / -12 )

women who got both vaccine doses in the same menstrual cycle saw a slightly larger change to their next cycle length, on average two days.

A vaccine in the arm should have no effect on the reproductive organs down south.

The fact that experts don't know why the menstrual cycle changes and can only offer theories isn't reassuring.

These vaccines have not been properly tested.

a slightly larger change to their next cycle length, on average two days. About 10% of them had a change of eight days or more

Wow! My goodness!

10%??? 8 days or more???

That is a lot!

@Big Yen

This has nothing to do with anti-vaxing. This is about how safe is the vaccine for your body, and what changes or damages will occure after you took it.

I am not a woman, but I am sure that if my wife would have experienced a 8 days delay, she would never ever taken that vaccine anymore.

But lucky, she didn't have that experience.

I was going to post that despite the reassuring news contained in this article, some anti-vaxxer would be sure to come along soon and put a negative spin on it.

Question anything these days and your an anti-vaxer. Even though you might have had the vaccine. A return to the Middle Ages.

Averaging is precisely used to avoid giving too much importance to limited, infrequent reports that do not represent the actual situation.

Also, no there is no Pfizer data that shows accumulation of any of the vaccine on the ovaries, misrepresenting completely unnatural animal experiment results as if they could be extrapolated to humans is dangerous disinformation, if you do that it would be as valid to do the same with the rest of the results and say that 100% of all the unvaccinated subjects died of COVID.

A vaccine in the arm should have no effect on the reproductive organs down south

And it does not, the normal, expected immune stimulation can have a limited, physiological effect on delicate reproductive cycles, the same as exercise, a limited amount of stress, changing the routine, etc. All frequent reasons for a delay of a day on average.

These vaccines have not been properly tested.

The experts say they are, and have the scientific data to prove it, somehow a nameless person on the internet saying all the scientists of the planet are wrong is not something worth of taking into account.

10%??? 8 days or more???

That is a lot!

But not something as infrequent as you would like to believe, a mild fever for a common cold, changing jobs, some stressful event on life, etc. can make women even skip one cycle without any long lasting repercussions in their reproductive life. A vaccine that successfully mimics an infection to give a strong immune response against the actual infection can cause these transitory changes without it having any special meaning.

I am not a woman, but I am sure that if my wife would have experienced a 8 days delay, she would never ever taken that vaccine anymore.*

And how about all the other things that also cause this? "never ever" begin a new diet? begin an excercise routine? change her daily commute?

Question anything these days and your an anti-vaxer. Even though you might have had the vaccine. A return to the Middle Ages.

The problem is not questioning, the problem is spreading debunked false information to mislead others into making a wrong decision, which can validly be called to be antivaxxer propaganda. One thing is to ask "is this normal? does it happen with other vaccies?" another completely different is to lie and say "the vaccine accumulate in the ovaries and its dangerous"

What a nonsense reply.

How do these things change a woman's monthly period???

Daily commute is related to a woman's monthly period???

Man, if you have no argues that makes sense, you better say nothing.

Even not being a woman is not an excuse to not understand that anything that can cause stress can temporarily change the cycles, this may surprise you but even if you don't know something that does not make it nonsense, it just mean you need to inform yourself better.

There are many levels of stress ranging from a bad hair day to pandemics that shut you in your home for months. How stress affects your menstrual cycle is based on your unique brain and body.

Study offers reassurance, fails to deliver

It does, for rational people that understand biology, but no matter how much evidence is presented there will always be people that will reject science and will never be convinced that their preconceived ideas are wrong.

A fluid, which is injected into your body, and this fluid changes the biological natural system of your body, which is given to you from God or nature or whatever you believe in...nobody, absolutely nobody can tell me that this fluid is a good or safe one.

So, water is not good or safe? because it completely fullfills your description.

Vaccines have been demonstrated to be much safer than not vaccinating because they prevent the damaging effects of a virus that not only enters your body, but actively tries to disrupt your immunity while replicating uncontrollably. Not vaccinating would mean people choose to be exposed to bad and unsafe things, which would make those people whatever you want to call them.

some manufactured "consensus."

Intriguing expression. Notable that you didn’t elaborate on it.

Tell us more.

@virusrex

We are talking here about a vaccine, a fluid, which is injected into your body to keep you healthy. And not make you sick or uncomfortable, and not extend a woman's period for 8 days or more.

Stress, what you mentioned, doesn't have the purpose to keep you healthy. Stress is already a kind of sickness itself and has bad influence to a human's health in many ways.

But the vaccine, should not have bad influence to your health.

It is oposite, the vaccine should keep you healthy. Therefore it is made for.

I guess you agree to that.

Ignoring the examples that prove you wrong do not help your point, it only indicate you are not actually interested in what is healthy or not, just oppose vaccines because of your personal beliefs.

What do you think exercise is supposed to do? or a diet? exactly the same improve the health, and both can make people feel sick or uncomfortable, or even extend a woman's period or make her skip it completely for several months. This is not "a bad influence to your health" just a normal, expected, frequent reaction to biological or physical stress that have no actual impact on health.

According to you no woman should ever exercise or follow a better diet, because when some women do they skip their period which for you is "unhealthy".

Here's a link to the original study:

https://journals.lww.com/greenjournal/Fulltext/9900/Association_Between_Menstrual_Cycle_Length_and.357.aspx

The study is moderately encouraging but still inconclusive. Given that other doctors have noted that the lipid globules carrying the mRNA vaccines accumulate in the ovaries, the long-term effects on fertility and menstruation are unknown. These vaccines are still experimental, no matter what certain individuals claim. Take them if you want, but be aware that you're participating in an enormous drug trial with dubious informed consent.

And remember that this study is funded by the NIH, so it can't be rules spout that there will be implied expectations to produce the results the funder wants, especially since this is a highly contentious issue linked to the push to vaccinate everyone regardless of whether they need it or not.

Sorry but that is false, there are no such thing. This is dangerous disinformation that has no basis in reality.

Take them if you want, but be aware that you're participating in an enormous drug trial with dubious informed consent.

Again this is not true, this is only repeated in sites that promote dangerous and misleading information, the vaccines are no experimental in Japan, and mRNA vaccines have been fully approved in the US, people being vaccinated are not participating in any trial. They are being vaccinated to obtain the well proven benefit for their health, which greatly decreases the risk from COVID.

If a woman loses his period because of diet or excersise, what is the woman doing?

She stop or change the diet or the excersise.

So if the woman loses her period because of the vaccine, what will she do?

She will stop taking the next vaccine.

Maybe not all, but some.

This is from an article you can find:

Amenorrhea can lead to serious health problems, such as endometrial cancer or bone loss, so it should not be ignored.

you might experience other signs or symptoms along with the absence of periods, such as:

Milky nipple discharge.

Hair loss.

Headache.

Vision changes.

Excess facial hair.

Pelvic pain.

Acne.

Doesn't sound really healthy for me...but everyone is free to judge by themselves....

If a woman loses his period because of diet or excersise, what is the woman doing?

Healthy things that nevertheless temporarily affect hormonal balance without any real negative effect for her health, which is the whole point. She does NOT need to stop nor change her diet nor her excercise routine just because she lost a period. that is terrible advice that is contradicted in the references you are trying to ignore.

Again, this is a normal, expected, frequent physiological change that do NOT indicate pathology by itself. Only your complete lack of knowledge about reproductive health that exaggerate something out of proportions just so you can justify opposing healthy medical interventions.

Doesn't sound really healthy for me...but everyone is free to judge by themselves....

None of those problems have been described for vaccines, (or beginning a diet, or a daily routine of excercise), this is the important point.

Again, according to you doing a healthy diet or exercise is unhealthy and should be avoided, that should be enough to prove even to you that this is not actually something rational.

1 ( +6 / -5 )

None of those problems have been described for vaccines,

Losing the period is described for vaccine clearly in the article!

And the points which are mentioned above can be a health problem as a consequence if a woman lose her period.

Ignoring that, doesn't make you more convincing.

But like I said, I am not a woman.

I let them decide how to judge these points.

I guess stereotypes are born from a reason, but it had to be men overreacting and making such a fuzz over a delay of a period. There are many women that never have a regular period, others that get a delay if they drink one extra cup of coffee in the morning. Making this normal thing an argument is just proving once again that men ignore even basic women health.

-1 ( +3 / -4 )

To all the men here, a last tip from me,

Ask your wives or Girlfriends if they are happy and ready to probably lose their period after taking the vaccine.

Like I said, let the women decide.

It is not to us men.

This is consistent with the Pfizer data showing the vaccine nanoparticles accumulating on the ovaries. Just because most women haven't noticed any differences doesn't mean there is no damage. Time will tell.

Also, no there is no Pfizer data that shows accumulation of any of the vaccine on the ovaries, misrepresenting completely unnatural animal experiment results as if they could be extrapolated to humans is dangerous disinformation

It is data submitted by Pfizer to Japanese regulators. Lipid nanoparticles did accumulate at high levels in the ovaries. Obviously, this experiment cannot ethically be carried on women. But as I wrote, the results are consistent with many women reporting longer and more intense menses. Who knows what other long term effects will be observed as a result of this accumulation. Just because the app did not detect changes in most women doesn't mean there is no negative effect.

Obviously, this experiment cannot ethically be carried on women

that is the whole point, conditions impossible to met in humans is what give these results, so saying this applies to humans is false, and the reason why no institution of science or medicine in the world says the vaccine accumulates anywhere.

Like I said, let the women decide.

With true information, without exaggerating the importance of physiological changes without any pathologic meaning.

Like it or not, every person alive right now is a test subject of some kind-- either for the vaccines, or for the virus, or both. It sucks, but that's how it is. Anti-vaxxers worried about the newness of RNA technology surprisingly seem untroubled by the fact that covid-19 is almost just as new as the vaccines, and that it may not have had a totally natural origin. Even stranger, in the U.S. at least it seems to be the anti-vaxxers who are most certain that covid originated in a lab. And yet they refuse to get vaccinated because the vaccines are new, untested, unnatural...

We do not know the long-term effects of covid infection, either.
