hearing of this breakthrough infection so a question, can a vaccinated person who gets infected get long covid ?
The study confirmed what's already known: That it's very rare for fully vaccinated people to get infected or sick with COVID-19. But it also found lingering COVID symptoms did develop in a handful of breakthrough cases.
Regev-Yochay and others stress that the results need to be confirmed by additional research involving many more patients who are followed for much longer. It could be a false alarm, the symptoms could be much rarer, or they could resolve far more quickly than the months of symptoms that typically plague those suffering from long COVID.
I think we know that vaccines don't always work for some people. Usually a tiny % but even so the more people who are vaccinated the less those people to catch it
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.It is becoming apparent that vaccination does not offer complete protection against infection.
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.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.
Possibly the 60% relates to protection v infection \ any symptoms and the 95% relates to protection against severe symptoms / hospitalisation.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.
No. Read the EMA info.Possibly the 60% relates to protection v infection \ any symptoms and the 95% relates to protection against severe symptoms / hospitalisation.
Where is the specific link to delta variant data.No. Read the EMA info.

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.www.yalemedicine.org
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.Is there data to tell us if these were people who got the AstraZeneca vaccine or one of the others?
I wonder if that's largely down to AZ being double dose versus Johnson being single dose.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
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.I wonder if that's largely down to AZ being double dose versus Johnson being single dose.
Yet, we have been told by government that they will always be open and truthful to us regarding Covid. As someone who only had the choice of the AstraZeneca vaccine, I would be concerned and actively looking for a booster to provide further protection.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.
