Finally got it to translate. Yes, there are small studies that contradict each other and need some serious review. There are usually two effectiveness ratings. First is catching it while vaxxed and having mild symptoms and the second is hospital and ICU - effectiveness at keeping you out. Sinovac is <50% at you catching it with delta, maybe much lower, but it seems to be more effective at keeping you out of the hospital and ICU. I read pop articles like this, but look for good ones from med journals that are summarized, because half of it is meaningless to me. This article doesn't really tell you anything that we didn't know weeks ago, and it states it poorly. The big question is what is its effectiveness at keeping you out of the hospital and ICU. Since no Western countries are using it, it isn't appearing where I look except for the large 10.2 million meta study that doesn't included Delta. It had good effectiveness there though. The Thai studies contradict each other and are small, and it isn't clear if they are peer reviewed. NEJM https://www.nejm.org/doi/full/10.1056/NEJMoa2107715 Results The study was conducted from February 2 through May 1, 2021, and the cohort included approximately 10.2 million persons. Among persons who were fully immunized, the adjusted vaccine effectiveness was 65.9% (95% confidence interval [CI], 65.2 to 66.6) for the prevention of Covid-19 and 87.5% (95% CI, 86.7 to 88.2) for the prevention of hospitalization, 90.3% (95% CI, 89.1 to 91.4) for the prevention of ICU admission, and 86.3% (95% CI, 84.5 to 87.9) for the prevention of Covid-19–related death.
Can't find the study, must be in Chinese Antibodies triggered by Sinovac Biotech’s COVID-19 vaccine decline below a key threshold from around six months after a second dose for most recipients, although a third shot could have a strong boosting effect, according to a lab study. Chinese researchers reported the findings from a study of blood samples from healthy adults aged between 18-59 in a paper published on Sunday, which has not been peer reviewed. https://www.bworldonline.com/study-...id-19-shot-fade-after-6-months-booster-helps/
2nd jab today of Sinovac, any jab is better than no jab IMO and happy to have it... will try to get a booster in a few months though...
There's risk to Aztrazeneca and little risk to Sinovac. 1st jab of AZ you have a 1 in 50,000 chance of blood platelet problems. 2nd jab 1 in 500,000. Depends on your age and there is an age layered study around. Sinovac a very remote chance of Guilon Barr(sp?) syndrome, which usually fades. So Sinovac is less risky than AZ.
The Phils is doing mix n match studies now on Sinovac, so keep your eyes peeled. "When participants in some cohorts were given a third dose (Sinovac), about six months after the second, neutralising antibody levels after a further 28 days had increased around 3-5 fold from the levels seen four weeks after the second dose, the study showed." https://www.thedailystar.net/health...er-about-6-months-booster-helps-study-2138051
Sounds like the Philippines may need to start offering booster shots to the elderly before everyone has had the chance to get their first two. I think my visa is going to run out before I ever get a chance to get vaccinated. Starting to get concerned if I will be able to return to the Philippines in a reasonable amount of time.
My wife had her J&J jab at the VA Manila clinic. In and out in an hour. No after effects so far. They are taking walk in 10 am till 2 pm. I am vet, but no disability, open to all vets and their spouses.
I ask for a booster with Johnson and Johnson in Bacong, already got Sinovac, the answer was no, not all are vaccinated yet, I understand and respect that
