Long term vaccine adverse/side effects - how & what?

[scaredsadandstuck]

Basically this - can anyone explain a bit more to me about how the covid vaccines could cause long term side effects or delayed adverse effects? How would this work scientifically/biologically?

Is it in the same way that some people get long covid, could you get long covid vaccine side effects?

What are the scientifically plausible delayed adverse effects that could appear years from now?

Are the risks of long term or delayed adverse effects more likely with one type of vaccine (e.g. mRNA) than another? If so, why?

I came on to ask this very question! I wonder would a long term issue be a faulty immune response. One argument is that the vaccines may have instructions or our immune systems which are too specific, and may have immunological consequences for the vaccinated. I dont know, and the science community doesnt seem to be sure either.

A similar question that I am interested in what is the potential 'worst case scenario' for pregnant women? What's the worst thing that can happen to the baby?

I had my first dose of Pfizer on Thursday. That morning, I had done a test and it was negative. When I got home I saw that the test had a faint second line. I did another test and it was positive. 2 more confirmed that I am pregnant.

The guidance where I live is that pregnant woman should get the vaccine only if the benefits outweigh the risks as there is no evidence showing adverse results, but none to show there arent any either.

Pregnancy test, not covid test!

Ah congratulations @Anonapapple that's lovely news. Can you ask your Dr about any possible risks?

Re the long term impact of a faulty immune response - that's interesting, do you mean that your immune system could over or under react to a virus that was similar to one you'd been vaccinated against?

My assumption/understanding has always been that a vaccine 'forces' the type of immune response you'd have if you were exposed to a virus 'naturally' (i.e. catching it from someone) without making you come down with the full blown illness. So if that is correct - and I'm not sure it is or not - I have never really understood how they could do more harm than catching the actual disease, or how they could cause adverse effects totally unrelated to the disease (eg. the whole Autism/MMR debacle).

Take the blood clot issue with AZ - would people who have experienced clots have been highly likely to have experienced them if they actually got covid? Is that how their body reacts to the virus, whether they are exposed to a small, controlled, specific part of it given by vaccine or by catching it from someone? Would those people who are experiencing ongoing side effects from the vaccine have been left with long covid if they'd have caught it?

This is a hopeful bump that someone with vaccine knowledge will be able to provide some insights!

Thank you. Still in shock!
I follow an interesting channel on YouTube. It's called DarkHorsePodcasts. It's two evolutionary biologists who are interested in everything and they give really calm, balanced opinions and I find them very trustworthy. They aren't anti vax or Covid deniers at all, but their stance is that Science should be open to exploring all aspects of any given topic, and they have interesting conversations on possible hypotheses and break it down into a way I have found useful. Ultimately I got the vaccine but I felt like I had done my homework and wasn't going into to it 'just because'.
