Covid vaccines - thread banned users in First Post

This is a misrepresentation of the study. Nowhere does the study say it is "almost useless". It talks of "modest protection" - against infection.

But the real elephant in the room is that you continue to make unqualified statements about the vaccine's effectiveness - but excluding any reference to its effectiveness versus severe covid and hospitalisation. This is misinformation.

How about responding to my previous points?

You continually ignore any reference to protection against severe covid in your posts about vaccine effectiveness, deliberately omit in fact. This is a crucial aspect of their effectiveness.

Boosters are given to health care workers and those most likely to have other medical issues... so more likely to have be tested. At risk groups.

You have entirely failed to show that such factors were controlled for.

The people who got boosters are not a random group.

You are making a statement of fact re causation without foundation.

Important to point out its a pre-print study.

They found an 'association' that the group of people who had the most shots had the highest risk.

But the difference in risk based on this factor is slight as far as I can determine. And such a slight difference could be due to confounding factors.

The key questions is whether they have successfully controlled for a priori risk or testing behaviour or failed to consider a confounding factor. For example the study was not actively testing participants but relied on self reporting. It does not appear to distinguish between symptomatic v asymptomatic infection. Is there possibililty that people with more doses are also testing more.

Because what the data is based on is people who reported a positive test.

Which is where peer review comes in.

And if the study does stand up to review, and confirmed by other studies - then the findings need to be balanced out by the relevant authorities versus the 30 percent effectiveness 'boost' from the extra dose and considreration of how the booster affects severe covid protection.

Well done. You did exactly as I said. One individual case.

In the responses to that University students article:

"We have some major concerns about the choice of hospitalization as the primary measure of benefit. From the onset of the pandemic, healthcare providers, scientists, and public health experts in higher education have been learning from shared experiences, research, and evolving medical knowledge about the best way to safely populate college campuses with students, faculty, and staff. Hospitalizations averted is not the only marker of morbidity that is relevant to the college student population and given the rarity of severe disease requiring hospitalization in young, generally very healthy adults, hospitalization is not a good choice for a marker of COVID-19 related morbidity. We have also strived to minimize the risk of missed classes, severe illness, and need for prolonged medical leaves of absence given the potential adverse academic consequences of illness for students."

I would also add the study does not appear to consider the benefits of vaccines in terms of reduction of covid cases short of hospitalisatiom but that impact students ability to study etc and daily life as normal

And yet does consider them in terms of vaccine impact!

This is not a fair and balanced study.

I think you need to re-read the post you quoted me on earlier.
