In case I'm reported for being anti vaccine, I know that there are associated risks to women who contract covid - including it being fatal in seemingly healthy young women. So I'm not totally against the vaccine, I just wish that we knew more before we dole it out to fertile young women who might be better off without it.

Somebunnylovesyou22 · 11/04/2021 07:10

I wish I had read comments like this prior to getting my appointment and would have decided against having the vaccine. I went in good faith thinking we all had to do this to get out of this mess. It’s really upsetting when people dismiss any kind of vaccine reaction. I know my body and I have not been right since having it and now my period is late which has never happened as I track it monthly and it’s 27/28 days without fail. We all care about long covid but what about people who may be affected long term from a vaccine. Why are the less important and urged to be quiet in case they put others off taking it.

My cycle is always messed up when I get ill - having a fever is a clear sign to your body that it's not safe to get pregnant.

It makes sense that a vaccine-induced fever would have the same effect, as your body thinks you're ill.

@Therewereroses

If you're past the reproductive age and female, if you're elderly and female, or if you're male, it might be fine. I'm not convinced that women who may wish to reproduce in the future are fully safe in taking this. I'm not going to apologise for saying that either. I just don't see why a healthy young female should take the vaccine when it might fuck with her reproductive system. We don't know just how much yet, but this thread would suggest that it has at least had an effect on some women's periods.
Lots of things have an effect on women’s periods - illness, a fever, stress, even anecdotally the flu jab. This does not mean they’re messing with the reproductive system.

Like many MNetters have reported, my periods were significantly delayed after first taking Pregncare supplements years ago. No one has ever been able to suggest why. But that hasn’t affected my fertility at all.

Gubanc · 11/04/2021 07:30

The vaccine hasn't affected my cycle at all. Just reporting here for the stats.

lightand · 11/04/2021 07:35

Seeing more and more posts like this.

It's pretty obvious that if your body is mounting an immune response to what it think is an aggressive new virus (but is actually the vaccine of course with no virus in it) then it will prioritise self preservation over reproductive processes in the short term. It would almost be worrying if it didn't! Your body is literally working to keep you alive, it doesn't care about being able to get pregnant right now. Of course this will subside once your immune response has done its job.

It's like when your body goes into fight/flight mode it stops/reduces actions like digestion to prioritise preserving life. It's normal and healthy!

diddlediddle · 11/04/2021 07:49

Genuinely blows my mind how few people understand 1. How the vaccine works and 2. How the body works, even in a basic way. Distrust in science and experts who have dedicated their lives to preserving health is just so weird.

You are saying/thinking that people will not be able to get pregnant for 3 or 4 weeks after the vaccination?

Ye, and they've listed menstruation changes as a side effect. Except. No, they haven't.

How does the vaccine work? How does the body work? Just give me the basics.
Therewereroses · 11/04/2021 08:09

@lightand She knows no more than you, I or Chris Whitty.

Nobody knows.

People are merely commenting about whether their menstrual cycle was affected notably by the vaccine or by covid itself.

We're not allowed to talk about that though.

Therewereroses · 11/04/2021 08:12

I suspect it would have shown up during trials but wasn't something they looked for. Women often don't get alarmed at slight changes in periods or their cycle. I'd love to see what side effects were reported during trials. I'd also love to see the proportion of women trialled vs. men. You can see it clearly here. Every woman who has reported unusual changes to their menstrual cycle has been basically told that they're being hysterical.

Therewereroses · 11/04/2021 08:13

Would love to know in particular whether women's menstrual cycles were tracked during the trials.

Ilovenutellaaaaa · 11/04/2021 08:16

Im glad to see this thread and know that it's not just me...my period has been very light after having AstraZeneca

diddlediddle · 11/04/2021 08:19

They probably didn't track menstrual changes because science is still irritatingly patriarchal.

I don't think noting changes after the vaccine is hysterical at all. It's good to be in tune with our bodies.

I think making assumptions about the vaccine causing malicious/long term impacts to fertility, hormones etc based on one or two delayed periods is probably over reacting because the changes are easily explainable by basic biology as per my original post.

I am not claiming to know more than the experts far from it, I am saying they know more than us.

I guess it is logically possible that if your periods are messed up for a few months by the immune response (as could be the case after any immune response to a real virus or vaccine) then it might make it harder to get pregnant in those months although obviously not impossible and some women will likely be affected more than others - that's the way humans are.

I'm not going to explain how the vaccine works - plenty of other great posts and pages about that.

Lol, I'm not an idiot. I know how vaccines work.

The problem with his idiotic analogy is that sometimes, you order pepperoni and you get a mushroom with anchovy pizza instead.

When you stimulate a response in the DNA and you get a desired response, that's good. Really good. Especially if it's stimulating an immune response which might make you immune to COVID. What is not good however is, the fella skimming your credit card while you're on the phone to the pizza shop. Or that stimulation of DNA and an immune response causing an umprompted and unanticipated reaction in the body such as in your adrenal glands or your ovaries.

Somebunnylovesyou22 · 11/04/2021 08:33

The AZ vaccine is a viral vector vaccine unlike Pfizer which is mRNA. With any new medicines/vaccines scientists don’t have all the answers right away. This is why everyone needs to report side effects to yellow card and then over time as it’s analysed conclusions can be made.
There hasn’t been a lot of time for these vaccines as it is being used in an emergency situation so it’s important that we are allowed to talk about side effects so people can make more informed choices going forward.

wasthataburp · 11/04/2021 08:34

@TheRealForReal

Is this why there are rumours the vaccine affects fertility?
That was my first thoughts!
Therewereroses · 11/04/2021 08:38

Incidentally, now that I think about it, while I was being investigated a few months ago, a lesion was found on an adrenal gland and the consultant wrote to my GP requesting a referral to endocrinology. My periods stopped from July to November last year and now are very heavy and punctual. I have never been diagnosed with covid or tested positive for it but if I was to hazard a guess, I would put money on me having had covid already. The consultant surgeon also noticed something on my lung. Nothing worth worrying about, but enough for him to wait to discharge me until my then covid test came back negative. Weird. I'm only thinking of all this now!

Mamascoven · 11/04/2021 08:40

@Circumlocutious If there is clear evidence that it reduces transmission then that is brilliant and those who are willing to take it/give it to their children to help everyone else get back to normal and hug their nans are clearly great people and very un-selfish.

But no, I still wont be taking any vaccines, nor will my children (who without a doubt have been exposed to covid). I'll be relying on my natural immune system that is excellent and has protected me for 26 years.

Champersandchips · 11/04/2021 08:42

I’m due to have my vaccine this week (and will have it) but can’t help worry about what on earth we may find this has done to us in the future.

FlyingFlamingo · 11/04/2021 08:47

@Therewereroses you asked for a simple explanation of how vaccines work Hmm

diddlediddle · 11/04/2021 08:50

@Therewereroses strange and unkind response to @FlyingFlamingo who helpfully and straightforwardly provided a link to information that you said you didn't have.

Clear now that your original statement was sarcastic. Genuinely I wonder how people like you with this kind of communication style get along in real life... you must find yourself in difficulties a lot of the time and you must have very little respect for others. There really is no need for it. One can disagree with someone without being sarcastic or rude.

I agree that there's a possibility of unknown side effects from the vaccine. I just tend to go with Occam's razor in the first instance - the most simple explanation is the most likely.
