hearing of this breakthrough infection so a question, can a vaccinated person who gets infected get long covid ?
can you get long covid after vaccination?
- Thread starter johnwilliams
- Start date
I presume it must be a possibility... though expect far fewer cases than in the unvaccinated population.
Studies would have only started on breakthrough infections.
And there are still a lot of unknowns re long covid, why some people get it and not others.
Some long covid sufferers reported that when vaccinated they felt it was almost like a treatment for it, such was their improvement

It seems too early to say anything definitive but this seems to be as much as we know so far from one small study in Israel...

Yes. Which is basically what the article and study that I cited say.

It is becoming apparent that vaccination does not offer complete protection against infection. Probably, not even much above 50 or 60% and, not for very long either.
The first cohort of fully vaccinated people were the health care workers, vaccinated in Jan. There are now numbers of them getting Covid, though, hopefully, they will be mild cases and not require hospitalisation.
Vaccination is great and everyone should get it, but we may need to accept the endemic nature of this virus.
So, keep healthy, lose weight, eat well, excercise, don't smoke, reduce alcohol and take care of those who are vulnerable. The vulnerable might need booster shots, on a regular basis. Hospitals will need to maintain a facility for supplemental oxygen treatments, mechanical ventilation and continued research into the management of Covid symptoms.
It is still early days in the roadmap of this virus and it is possible it will fade away into a minor inconvenience, like the common cold. That's the hope anyway. However, at the moment it remains a really nasty illness in the acute stage and can also result in chronic long term health problems for a sizeable number of people.

Surely that was clear before the current vaccines were even rolled out? There was zero expectation that Covid vaccines would be 100% effective and offer life-long protection.
This is simply wrong. The initial efficacy data for the different vaccines is clear and much higher than 50% in all cases. And as high as 95% in some cases.

Admittedly, how much/quickly protection wears off is not clearly understood yet.
How Long Will Your Coronavirus Vaccination Last?
Yale Medicine experts are continuing to study how long the vaccines will provide protection—and how that could impact booster shots.

Possibly the 60% relates to protection v infection \ any symptoms and the 95% relates to protection against severe symptoms / hospitalisation.
No. Read the EMA info.
Where is the specific link to delta variant data.

It is beginning to look like Covid is similar to flu, in that it produces an evolving set of variants, many of which are more likely to evade the current vaccines.
As such, it may be that regular targeting of dominant strains will be needed each year. This, unfortunately, is a game of educated risk, as it is not always possible to predict which strains will become dominant, prior to the wave of infection. Hopefully, the evolution will diminish, rather than increase, the nasty elements of this infection.
It is too early to say if the vaccines are lifelong effective. If they could achieve a 60% lifelong effect, that would be very good, especially for a vaccine produced so quickly.
The length of protection also crucial. A vaccine which produces 90% protection for 2 months is not much use. If a vaccine's effectiveness wanes after a couple of months, then that statistic is the one to use to demonstrate it's overall protection rate. It seems that Pfizer is down to 38% effectiveness in preventing infection, after only 4 or 5 months. But, it does seem to maintain 90% protection against serious illness for longer.
Israeli Data Suggests Possible Waning in Effectiveness of Pfizer Vaccine (Published 2021)
The new numbers still show overwhelmingly strong protection against severe disease but diminished effectiveness against infection.
From the outset, AstraZeneca is reported to be 67% effective against the Delta variant compared to Pfizer's 88%, but I haven't seen any comprehensive data, and certainly none in an Irish context. Until supply constraints are a thing of the past they may be reluctant to publish data on what option vaccinated people who contract Covid took as it may result in people refusing all but what they perceive as the most effective option.
We also know that efficacy reduces with time. From some of what I've seen, Moderna may provide the longest lasting, but they and Pfizer are signaling that booster shots will be required.
The AZ vaccine is a lot more effective against delta variant than the Johnson vaccine, not sure about the Russian vaccine but the sinovac vaccine is particularly ineffective against the delta variant which explains why new outbreak in China. But the development of the RNA technology by biontech is a game changer the Chinese will need to use the Pfizer vaccine or buy the license to produce it themselves
I wonder if that's largely down to AZ being double dose versus Johnson being single dose.
Maybe but Pfizer, moderna and AZ vaccines are the 3 best vaccines against the delta variant. The Chinese sinovac looks like its not working against the delta variant now, there is no data on how effective it is and the Chinese are not prepared to allow it to be scrutinized by international peer reviewed analysis. Like the Australians and new Zealanders the Chinese elimination approach is facing its biggest test now with the delta variant.
