Is Israel or the UK right when it comes to COVID-19 vaccine effectiveness?
According to one Israeli researcher, both sets of data could be correct. Here is why:

Is the Pfizer coronavirus vaccine 88% or only 39% effective against preventing symptomatic infection?

Two separate studies, one published by the Israeli Health Ministry and the other published in the New England Journal of Medicine late Thursday showed striking differences.

“This discrepancy is kind of unsettling and needs to be further investigated,” said Prof. Cyrille Cohen, a member of the advisory committee for clinical trials on SARS-COV2 vaccines at the Health Ministry.

Specifically, the ministry's study found that the Pfizer coronavirus vaccine was only 40% effective against symptomatic cases of COVID-19 and 39% effective at stopping infection at all against the Delta variant.

1. It seems what we see here, vacs are preventing more than they are not preventing.

2. Weren't the Israeli numbers a much lower sampling?

Seems I read that somewhere?

3. I read the New England study it doesn't define the efficacy of the vaccines it just says effective a

... it doesn't say infection or hospitalization / death

4. We (US) are more similar to Israel than to UK.

We were giving Pfizer to all age groups, from young to old.

9. We are more similar to the UK for the

timeline of when vaccines were given.

5. The Israel dataset seems to be more representative

It includes more time for the vaccination protection to wane and also includes the over 40 group.

8. Hard to tell, since they are not releasing the data.

That is what raises the most questions for me about the Israeli report.

6. The Pfizer vaccine has been shown to be highly effective

Against the Delta variant in a number of studies

7. Interesting -

When England launched its vaccination campaign, it did not have enough doses to vaccinate the population according to Pfizer’s recommended regime of two doses three weeks apart. As such, it spread doses out to between four and 12 weeks to allow more people to get at least one jab. Specifically, the new research showed that neutralizing antibody levels, the level of those antibodies responsible for defending cells from pathogens, were higher after the extended dosing interval (six to 14 weeks) compared to the conventional three-to-four-week regime.
