That 5 percent number is somewhat misleading. Studies have shown in the USA that if one of the 5 percent bunch contracts Covid, it is far less serious, doesn't affect the respiratory system, and doesn't require hospitalization.MOCHS wrote: ↑Thu, 03 Jun 2021 9:53 pm1.7 million people in SG have finished both doses.
Taking the 95% efficacy into account, you would expect 5% of them (88K people) to probably have less than stellar immune response. So I won’t be surprised if you read news everyday of vaccinated people being infected.
The optimistic data on the effectiveness include:BBCDoc wrote: ↑Thu, 03 Jun 2021 8:08 pmHere’s an example of infection rates among vaccinees, the data for Sinovac that led to WHO approval

if you are looking for Singapore specific, I don't think you are going to find any for many reasons. But it also would be quite difficult to do any statistically meaningful analysis as the numbers of cases have still been so low, and the vaccination levels only started to go up.x9200 wrote: ↑Thu, 03 Jun 2021 6:30 pmThere is a subtle difference between expectation of zero infection and reading practically every day about what appears to be a significant fraction of infected population being earlier fully vaccinated. Do you have any data showing the infection rate among the fully vaccinated? Unfortunately I could not find any. This would cut the speculations.
Different strains? Methodology?CDC COVID-19 Study Shows mRNA Vaccines Reduce Risk of Infection by 91 Percent for Fully Vaccinated People
It’s actually pretty amazing that they can detect viral fragments in waste water, technology has really come so far.abbby wrote: ↑Tue, 01 Jun 2021 10:24 amQuite surprised when I read this.

Exactly. Numbers in Singapore are far too small for there to be any useful statistics.ProvenPracticalFlexible wrote: ↑Fri, 04 Jun 2021 9:02 amif you are looking for Singapore specific, I don't think you are going to find any for many reasons.

But for more early vaccination countries like Israel, yes there's been studies published in respectable publications:

Depends Lisa what one tries to determine. 700 case from multiple clusters should normally be good enough to see some basic trends. Out of these 700 cases, 180 people were earlier vaccinated and 120 fully vaccinated. How would you explain this discrepancy to the CDC data concerning the same vaccines?Lisafuller wrote: ↑Thu, 10 Jun 2021 1:03 amExactly.

Still not enough data. But I'd expect that the highest risk frontline workers in Singapore, such as healthcare workers, airport staff etc, had higher % of vaccinated people, as they got their shots in Dec-Feb before the rest.x9200 wrote: ↑Thu, 10 Jun 2021 8:19 amDepends Lisa what one tries to determine. 700 case from multiple clusters should normally be good enough to see some basic trends.

To make it clear, I am not into any conspiracy theory but would like to understand what's going on.
I agree this could be the reason (at least one of them).ProvenPracticalFlexible wrote: ↑Thu, 10 Jun 2021 9:05 amStill not enough data.

The numbers are still not large enough to make any conclusions. PPF’s theory is plausible.x9200 wrote: ↑Thu, 10 Jun 2021 8:19 amDepends Lisa what one tries to determine. 700 case from multiple clusters should normally be good enough to see some basic trends.
