Looking for facts and data on what happens if I don't have my second vaccine

[Boringlynormal]

I tried this thread before but it ended up deleted - no idea what went on but I imagine it came down to different opinions on the discussion of vaccination. So I'm trying again but just looking (please please) for anything people know or any sources they can point me to about what immunity you get from just having ONE AstraZeneca vaccine.

I'm mid 30s and have had one (10 days ago) but due to the current situation am unsure about having a second. Obviously as well as waiting for news, part of my decision comes down to how much protection I will have from one dose and how long it will last so any info would be much appreciated.

(Pro vax, fully vaccinated, kids vaccinated against usual stuff and had my first AZ vaccine - this just comes down to the recent developments.)

Prettyvsure rhis ia reported in the published studies. You can gogle them.

My understanding is that you will have partial immunity from one dose. But obviously you won’t be able to have the booster for the new variant.

Feel the same. Unsure if DD 17 should have her second one.
She has terrible chest pain 8 days after unsure if related to jab.

I’m having second thoughts about my second vaccine, too, although mine was Pfizer. I had racing heart, sweating, feeling faint within about 5 mins of mine which lasted for over an hour - nurses said was a panic attack but have never had this issue with vaccines before. Wasn’t feeling particularly stressed about having it, either.

There won’t be data because no trials have been conducted on what happens to immunity with 1 dose.

Thanks for the links @Nootkah

I can see that one dose does give a certain immunity but what I can’t find (probably as they have had no reason to test it so no idea!) is what happens if you don’t take the second dose. Does immunity just stay lower or does it wane altogether?

Have been very poorly with side effects from AZ jab ( was keen to get it etc) but Oh my Lord, have I been ill! Crying with weakness and pain, vomiting, dizziness, bad stomach etc.
Will we be ‘made’ to have 2nd dose by the passports, our employers and so on?
Any ideas, Mnetters? I’m not sure I can go through this again!

True. But they must have some idea?

Here's an american article on one shot of Pfizer.

From what I have been told by several medical people, people generally do not react or as much to second AZ dose.

So if it is due to reactions, may be worth asking people you know who reacted to first dose how they were with second dose. Nearer the time.

I doubt we will be able to say, no I had one dose now I want Pfizer two doses, or Jansen one or Novavax etc. We did not get to choose the first dose.

I'm sure when I had my 1st vac, the nurse said 65% immunity but you can still get it and spread it, so 2nd vac important.

Obviously most of the facts and figures only relate to immunity on a societal level, so as I presume you’re only concerned about your own situation then I don’t know that you are going to find out anything that will help you.

I have had one dose of the AZ vaccine. I am also participating in a research study which includes antibody testing. I had a test three weeks after my first dose which shows that I have antibodies due to the vaccine at a level sufficient to trigger a positive test. But obviously that is individual to me.

The plan is for trial participants to have regular antibody tests so I presume that will be one way of monitoring how long the antibodies last, over a period of months/years. I’m sure a number of similar trials are being carried out.

I will be having my second dose as I would rather have as much protection from Covid as possible.

And those who are mentioning unusual or severe side effects to the vaccine - I hope you’re reporting them via the yellow card system.

If you only have one dose you risk not having longevity is the scientific answer apparently

The French have been doing some research into only having one dose if you have already had a positive covid test ( I don't have a link for that sorry) However I wouldn't judging by some of their vaccination descions totally trust any French research at the moment. They seem way to political with it.

From what I have been told by several medical people, people generally do not react or as much to second AZ dose.

So if it is due to reactions, may be worth asking people you know who reacted to first dose how they were with second dose. Nearer the time.

Not reactions per se - I did have fever, chills, aches and a really rough day followed by a fairly crappy day but I'd do that all again without hesitation. It's the blood clot thing that's spooked me. I'm mid 30s and got it as a carer. If they ban it for under 30s I'm not sure how safe I'll feel. It depends what data comes out about the other cases I think.

Thanks @MrsFezziwig that sounds like an interesting study. Hopefully one that will help people in the future.

One dose partial immunity for around 90days. Not sure after that how quickly after that it lowers without the second dose.

It is more dangerous for our society if we have so many people now only getting first dose only, as there is a danger that it can create an escape variant. That variant could become even more dangerous and making vaccine less likely to be effective.

Read up on the scientific explanations on escape variants in covid-19 particularly with delay in the second dose. I had a couple of good links I left in a similar previous post, but the whole thread ended up deleted so I don't have them to hand.

Also I have had my first dose of Astra Zeneca, and I felt horrendous flu like for 48hours and mildly unwell for another day. Regardless, I absolutely 100% will be getting my second dose regardless, even if I feel just as unwell again or worse. I'd rather short term feeling awful than the much more severe illness and risk of death from covid-19. Not to mention the further very real risk of long covid which is potentially life long and completely disabling .

Yes some people feel awful after vaccine, but it is very short lived and it is temporary. Also the side effects I had were all listed to be expected. I echo pp on the importance of reporting via yellow card on unusual and or severe side effects.

I will also take the minimal risk of that extremely rare likelihood of those clots, in the vast numbers of successful millions of doses given. I have taken as much risk in the pill and other meds in my life. If I am even one of the extremely unlucky ones in those rarest of numbers from that clot type, I would still rather go out like that quickly than a prolonged horrible death.

The second dose is imports for longevity of immunity. You’re immunity from the first jab will likely drop off. You will also need two doses for vaccine passports/travel.

Yes if vaccine passports are brought in you’ll need two doses.

Under 18s get Pfizer only in UK (AZ not licensed for under 18s), so assume you are based elsewhere.

Chest pains that have lasted this long are something you should have reviewed by a doctor. And you should make sure they record the side effect with whatever the offer vial body it that collates them in your country. Here, it's via the Yellow Card scheme, which the public can add to directly, but it may be different where you are

Is the concern about stopping the AZ in younger people due to variants increasing?

This was always the risk with they way it was being rolled out.

Anyway make the decision based on how you feel and not bloody covid passports. It is heinous the government is effectively forcing the young this way.

Please can everyone stop comparing the rare AZ clotting issue to clots from the pill. It is a different kind of clot affecting the brain and coinciding with low platelets.

I'm sure one of the reasons for vaccine passports is because of people being jittery about the second vaccination, I haven't decided whether to have the second jab yet but don't intend to use the vaccine passport anyway so it won't make any difference that way. You should choose to have your jab because you want it not because of the passport.

Will we be ‘made’ to have 2nd dose by the passports, our employers and so on?

This bloody passport effort is the only reason I'm having the second one in a couple of weeks. I don't want it, but it's hardly a bloody choice if you want to return to some form of normality.

No, you should choose to have the second jab because you are then contributing to herd immunity, meaning there is a much reduced chance of the virus mutating to a new variant which potentially negates all the work we have done so far, putting us all back to square 1.
Educate yourself on the real chance of getting a blood clot and then.. have your second dose of vaccine!
