We may need to differentiate between those fully vaccinated and those taken the first dose only.

For Bukit Merah cluster, most are FULLY vaccinated.
We may need to differentiate between those fully vaccinated and those taken the first dose only.
Last night ST reported a school bus uncle (fully vaccinated) went there to dabao food, was tested positive. He developed fever, flu and fatigue so he went clinic to seek treatment where he tested positive.
For who tested positive, did they really queue 30 mins to dabao? If no, that means transmission of Delta variant needs less than 30 mins for transmission? Then maybe our trace together need to be configured to less than 30 mins?
For Delta Variant, it was reported in UK studies that one needs to be fully vaccinated to be effectively protected. For those with only 1 dose, it is as good as not being vaccinated. So those who took only 1st dose and had to delay their 2nd dose, are at risk. -
I seriously doubt queueing is the problem unless you were standing next to the infected stall assistant all the time. When queueing you stand near other customers in the queue.
Fomites would be more likely. -

There is a problem with testing strategies of once every 14 days if the incubation period for the delta variant is as short as 2-3 days. 14 days will be more than enough time for super spreading clusters.
What the Chinese experts are saying seems to be consistent with our own experience with Changi Airport T3, Tan Tock Seng, MINDSville, Jem and now Bukit Merah View.
Don't say nobody warned us just because no US, UK or European expert has said it yet har. -

I recall a chart from MOH which showed that 91.7% of non-vaccinated folks also showed no or mild symptoms when they were covid positive. Same magnitude as the vaccinated folks. So perhaps not entirely true that vaccination has helped to lower the severity of this current wave.
I think we may have to change our definition of \"safe\". In earlier days, when we knew less, those who contracted Covid-19 got sicker, and fewer were vaccinated, \"safe\" meant not getting Covid-19 at all, and keeping the cases to as close to 0 as possible. Now, many cases are asymptomatic or with mild symptoms, and few end up seriously sick (this lower severity is attributed to more being vaccinated, even though the vaccines don't prevent transmission entirely). So a modified definition of \"safe\" may be needed, which allows for a certain level of transmission as long as the no. of seriously sick cases don't threaten to overwhelm our medical facilities. Perhaps short targeted lockdowns and testing (e.g. 1 mall or office building, a few residential blocks, etc.) will be carried out now and again when a cluster grows beyond a certain size, while the rest of the nation continues as per normal. I believe this is what we will get to once enough are vaccinated.lee_yl\" post_id=\"2027472\" time=\"1623996025\" user_id=\"17023:
No one is denying the need for S’pore to stay interconnected to the world. The challenge is how to stay open while still keeping safe.
Remember the Mindsville cluster? Even with 91% of the residents vaccinated, 13% of them tested positive. Extrapolating to 6 million population, do we need to get ready for roughly 780K to be down with covid? So will this figure still be considered “safe”? For the Delta variant, we are lucky that most cases are mild or no symptoms but we can’t be sure for next year’s new variant (even for the vaccinated folks).
Today, we have 11,000+ had who have been to Orchard ION, who came forward to be swabbed. Only 11K swabbed because we are in phase 2 HA without dining in. Had we already opened up to tourists and also allowed dining in at ION, I think can easily increase 10 times more or 110,000+ turn up for swabbing! And that’s testing for 1 potential mall cluster only. I don’t know how ring fencing is going to work when we further open up.
Actually I think if our cases increase and we have to go into hiding once a year, it’s actually not a bad idea as it has been proven to be able to effectively stamp out covid. Maybe it will become a new way living. Like DH puts it, just treat it as we need to have our version of ‘puasa’ once a year,

We already just experienced our first \"covid Delta variant mutation puasa\", from May 16 to June 13 or June 21, this year (2021)

am thinking if NZ can hunker down to eradicate coronavirus, can we do so too? what is the price to pay?

Correction here: https://www.straitstimes.com/singapore/health/some-cases-in-bukit-merah-market-cluster-had-queued-at-popular-stores-for-30
For Bukit Merah cluster, most are FULLY vaccinated.starlight1968sg\" post_id=\"2027522\" time=\"1624066086\" user_id=\"14025:

\"Citing the example of the Bukit Merah View cluster, he said 32 per cent of cases have been vaccinated, but 50 per cent have yet to receive the vaccine. The rest of the cases have either received just one dose of the vaccine, or have not yet derived the full protection afforded by the vaccination's two doses.\"
However, I am surprised at his analysis and conclusion to this statistic though.
I am all for the vaccination and I am not an anti-vaxxer but how does this statistic support this statement?
\"This does support the view that vaccination does protect you and reduce the risk of you getting infected, as opposed to those who are not vaccinated,\" he said.

I hearsay that the dozens of fully vaccinated people in Singapore who nevertheless became infected all took the Sinovac vaccine. :roll:
