Taiwan mortality rate at 4% is twice world's average. The number of cases has been underestimated is given as there is lack of mass testing and the high mortality rate.

Also cremation increased by 55% over same period last year. Even mortality rate might be underestimated. On top of that more than 178 have died of adverse reaction from AZ vaccine.

Are there any Taiwanese references of this 178 deaths from AZ vaccine? This sounds serious. Many people are taking AZ!

Most of the 308 health workers vaccinated with Sinovac's Coronavac vaccine in Kudus, Central Java, a district recently hit hard by the novel coronavirus Delta variant, recovered from the disease last week, an encouraging indication of how the Chinese-made vaccine fare against the more infectious variant.

Badai Ismoyo, the Kudus district health department head, said administering the Covid-19 vaccine to health workers in the local area has proven effective in protecting them from the worst conditions.

"Today, 90 percent of health workers who are self-isolating can return to work and return to serving the community," Badai said in a statement on Friday.
"This is encouraging news. In addition, it also shows that the vaccine given to them is really effective in protecting against the worst conditions," he said.

Maybe bcoz some of the shots are expired, on top of the fact that AZ is dodgy to begin with. Japan donated expired AZ doses to Wanwan. This was posted before, but seems appropriate now for a repost.

Honestly, this is a little ridiculous... From above, NYT and Jakarta globe are writing about the same news and have the exact opposite take.

This is in addition to the millions of 5.56mm and 7.62mm shots already administered in Afghanistan with 100% effectiveness (cannot get sick in Heaven)

You got me there, careless use of terminology.

But I'll still stand by my assertion that the figures aren't as alarming as some will take it to be viz vaccine effectiveness.

What is of interest to me in a Covid cluster map is that it's a quick visualisation of the effectiveness of the efforts to identify and contain the spread of the infection (based on the number of unlinked clusters and lengths of infection chains)

, we see that in the latest large cluster at Bukit Merah View, 31 of the 85 infected (or 36%) were fully vaccinated. The first case in the cluster was a fully vaccinated individual who tested positive on June 10th after experiencing COVID symptoms, which means the actual infection happened at least several days before that.

Singapore fully vaccinated 32% of its population by June 7th, 34% by June 14th, and 35% by June 21st. So, the fully vaccinated actually make up a slightly higher fraction of the latest Bukit Merah View cluster than in the general Singapore population!

Of course, the population exposed to the Bukit Merah View market may have vaccination rates that differ from the general Singapore population, e.g., if mostly older people are exposed and older people tend to have higher vaccination rates. However, viewing the cluster by age, we see that the median age in the cluster is somewhere between 40 and 50, at most only a little higher than Singapore's overall median age of 42 years, so vaccination rates of the population exposed by the Bukit Merah View cluster is unlikely to differ dramatically from that of Singapore overall.

Given the available data about the Bukit Merah View cluster, it is highly unlikely that Pfizer and Moderna vaccines have anywhere close to the ~95% efficacy against infections that Western media likes to claim while putting down the "low" efficacy of Chinese vaccines. The high ~95% efficacy of the mRNA vaccines is for prevention of moderate and severe disease, against which the Chinese vaccines also have similar efficacies. Before the Singapore results, we didn't have any data on how well the mRNA vaccines work in preventing asymptomatic and mild infections as none of the other countries using the mRNA vaccines had vigorous contact tracing and testing programs that tried to catch all infections. Now with the Singapore data, as well as the Mongolian data where we have Pfizer and Chinese vaccines being used in the same setting, we have some pretty strong evidence that the mRNA vaccines are not significantly more effective than the inactivated Chinese vaccines despite the much higher risk of side effects with the mRNA vaccines.

Vaccine effectiveness (VE) % = ((Attack Rate unvaccinated – Attack Rate vaccinated) / Attack Rate unvaccinated) X 100 Attack Rate unvaccinated
(85 - 31) - 31 / (85 - 31) = 42.59 %
