Coronavirus 2019-2020 thread (no unsubstantiated rumours!)

It's not that simple. Conflicting studies exist.

The first study indicates a 50% difference in favor of mRNA after 4 doses (though 3 dose mRNA = 4 dose inactivated virus). The second study indicates a ~10-15% difference in favor of mRNA after 3-4 doses. That difference is larger with less doses, which is also consistent with the study you linked, though that could be because of how recent the dose is, rather than how many there were.

I also don't like the propaganda being pushed by the West regarding how Chinese vaccines are "useless," but there is data suggesting less effectiveness, though the margin might be only ~10-15% judging by the Hong Kong study, which isn't a lot. The Singapore study, however, is more of a problem. With a fast moving and ever changing virus, and new vaccine boosters being pushed out regularly, it's not likely that we'll get enough data to say one way or another until the wave has already passed. This makes it easy for people to push any agenda they want.

In short, I'm cautiously optimistic about inactivated viruses, presuming they update them quickly with new strains. But mRNA technology also shouldn't be dismissed. Having access to both would be ideal, in case one technology does turn out to be better in the long run.

We have gone through this before.

The first study can't be conclusive because of the too small size sample (according to the authors) for the inactivated vaccine and its combinations.

Otherwise, a 3-dose combination (2-dose inactivated, 1 Pfizer booster) is actually better than 3-dose mRNA in Hospitalization and Severe cases.

From the data tabulation in the link:

3-dose combination Against 3-dose mRNA
67 Against 76 for Hospitalization cases.
9 Against 12 for Severe cases

So, does that mean a 3-dose combination (2-dose inactivated, 1 Pfizer booster) is better than 3-dose mRNA?







For the Hong Kong study, I commented on it before.

• 20,953

"The big problem is that the study did not break down the ≥65 years pool.

The study is using data from the Hong Kong population, the same locality as those used in the few other studies posted here previously, including those from yourself, that did break down the >= 60 years pool to a few age groups, which shows that the efficacies of the 2 types of vaccines to be about the same for 3 doses. "

It's important to consider this because Sinovac/Sinopharm is known to be increasingly more popular with the older age groups (in Hong Kong), which is associated with higher case fatality, which would then skew the calculation towards a higher fatality rate for the whole >=60 pool.

You should indicate the title is sarcastic as many people may not look at the actual video.

great discussion on the china COVID situation and western responses. a lot of experience from the ground and why the protests fizzled so quickly.

 

[Bellum_Romanum]

Constructive criticism of the government is not allowed here. You will be branded a west loving propagandist. So why even debate here.



Says by the person who was constantly paffing for China to open up neglecting the very real concerns and loss of lives accompanying such western style opening.

Get off your high horse.

Japan is quick to impose quarantine rules for Chinese travellers. Even Malaysia. Chinese people should not consider travelling to these countries for tourism anymore. Only travel to friendly countries.

Yeah Japan, Italy are the most stringent, Malaysia is just monitoring. Philippines and US are considering the same. Ironically India is one of the least stringent and does random testing. Japan and US are definitely political, even in their reason for the monitoring. it also mentions South Korea putting limitations but I cant find their restrictions anywhere.

GUSAID which basically tracks variants states that Chinese scientists have been quite forthcoming and their infection variant is the same as those around the world. So these limits are mainly political.

personally confesses travellers should just avoid Japan. Italy and the US. It’s obvious they don’t want confesses travellers there.

For @Icmer @Petrolicious88 @henrik @Overlord had to include the Indian fella here who loves to provide lecture on what China should be doing, ought to be doing etc..which is typicaI Indian blabbering. How in the world Indians like yourself find the chutzpah to critique China's affairs on just about anything is BEYOND COMEDY. I am not sorry for insulting your country, but your country would be the last thing we would ever take advice from on anything period. America, Japan, South Korea, and Europe sure, India? GTFOH.

Who’s Indian who’s Chinese. Who cares.

Don’t put the words “insult” and “sorry” in the same sentence. It lessens the effect.

India has issues, but it’s not all bad. Be humble - You just told me to “get off of my high horse”.
And It’s ok to take advice from America, Europe, Japan? Really. That’s new.

Statistically there will always be edge cases. For example, the head scientist of the Sinovac trial in Indonesia died of COVID, and other doctors were known to be hospitalized when Sinovac was the only available vaccine there at the time. Sinovac also has a higher risk of Bell’s palsy. Again, these are edge cases. Also, I don’t agree that your post debunks anything I said, as my posts mention increased autoimmune effects after mRNA and I never received mRNA myself or recommended it for China. I only clarified its relative efficacy and some misunderstandings about domestic mRNA trials.

Across Indonesia, at least five doctors and one nurse have died from COVID-19 despite being vaccinated, according to LaporCOVID-19, although one had only received a first shot.
