100% is from WHO, not Serrana.
Then again, if one believes the Americans, what do WHO know?
Personally, I am beginning to prefer Sinopharm over Sinovac...

I guess we are not epidemiologists so we can only wait for more comprehensive studies to be released by the authorities.

As a lay man, I know 27000 out of 45000 adults of Serrana (60%, excl. preggers, elderly & teens) had taken the CoronaVac vaccine (by SinoVac). Brazil had lockdowns, curfews, restrictions throughout that period of experiment (Feb-Apr), so movement was restricted, which will skew their results too.

In contrast, from Feb-Apr, Singapore had only inoculated less than 20% with those 2 brands, excl. vast majority of our 45-59yo adults. And we were in Phase 3, party time.

Next, let's look at the variants of concern. The variant that CoronaVac was testing/fighting against in Serrana was P1 (gamma), not B.1617.2 (delta). Delta variant we see here is apparently more transmissible than gamma. It has reached a new high of 81.5% in the past 4 weeks in Singapore (No 1 per Gisaid ranking). So we can't compare apples with oranges.

To be fair, we may have to watch Guangzhou closely. However, GZ's sample size's too small. Just 17 delta cases had been found, quarantined or blocked at the borders, so it's hard to see the real efficacy of whatever the Guangzhou residents were jabbed with.

Indonesia, which also uses CoronaVac, had reported 3 strains - alpha, beta & delta in early May. To date, they only have 32 delta cases (0.0x% per Gisaid record) vs SG's 358 cases (81.5%).

Yes, the deaths in Serrana had dropped. Let's look at Singapore's deaths during that period. We didn't have that many deaths prior to kappa & delta escaping here in April, so I'll look at the 30th (imported case from UAE), 31st (TTSH), 32nd (TTSH), 33rd (Changi airport) deaths.

Nothing on their vaccination status had been reported. What about the businessman who returned from UAE (SinoPharm+Pfizer)? So we cannot conclusively judge if the vaccines we're administering in SG are less than efficacious.

Now let's move on to hospitalisation of ''severe'' cases. They call it 重症保护率. In the Serrana experiment, hospitalisations dropped by 86% and symptomatic cases by 80%. That impressive % drop could be due to Serrana having very high confirmed caseloads at the start of the experiment in Jan.

Around that time of their experiment, Singapore did not have very high caseloads. We were seeing 0-2 community cases daily for a long while. As for hospitalisation of ''severe'' cases 重症, we have had 5 in ICU which then dropped to 2 now after delta attacked TTSH. There are currently 231 symptomatic, non-severe cases still in hospital, not in ICU.

Hey, it's not that bad wor...

I'd be more convinced, if they lock up 27000 Hongkong adults above 18, who had received 2 full CoronaVac jabs, on Lantau island and infect them with delta variant to obtain real-world data.

Anyone kena ‘‘possible exposure’’ or swab orders for visiting Yuhua CC (Raffles Medical) and Yew Tee CC (Healthway) vaccination centres on 21 May and 24 May respectively?


Are the vaccination staff going to be quarantined?

We must also check the CC’s history before booking a vaccination slot.

I wonder if minmed vaccination staff cld be stressed with new surge in vaccination numbers. Hope they get additional manpower.


I saw in the news, a private clinic got all the hordes fr every part of the island. This cld be avoid if the press inform clearly inform other centres to spread out. The doctor & nurses there overwhelmed & said ppl cld hv gone to their nearest clinic.

So, thinking manpower shld be expanded so the staff at minmed can hv longer or more breaks. Time off for meetings, reviews or training/re-training. Mistakes do happen & this one originates fr the individual. The minmed staff do not need more stresses fr lawsuits. Who wld want to do the job if they’ve to face lawsuits on top of shadow of mistake bearing over their head? Just thinking aloud.

2 unlinked community cases today. :sad:


hoping for zero unlinked

Can anybody point me to how many 12-15 year olds were actually in the clinical trials in the US for the Pfizer vaccine? All I can find is 2,260. How many more have had the jab in the US and Canada?


It looks like Singapore may well become the largest real world trial for this group. Congratulations. Keep fingers and toes crossed.

I literally dilly dallied till the 14th day & made a last-minute decision to book a next-morning appt since DH would be around to monitor my symptoms.

Not sure about the kids.

Sorry for asking without reading all… looks that that doesn’t have data on which vaccine yeah…
