February 11, 20224 yr BANGKOK (NNT) - Thailand’s leading virologist has indicated that injecting the 3rd shot of AstraZeneca vaccine, following two initial jabs of the same vaccine, does not provide a substantial boost to COVID immunity. Dr. Yong Poovorawan, head of the Center of Excellence in Clinical Virology at the Faculty of Medicine, Chulalongkorn University, explained that the practice, dubbed “Triple A”, yield less potent result due to the fact that the immunity provided by two AstraZeneca doses would decrease over time. And after receiving an AstraZeneca booster dose, immunity increases by “one log scale or a little higher” than after receiving two doses of the vaccine. According to Dr. Yong, a study by his office produced an identical result as the one from Oxford University on the matter. He recommended people to get an mRNA booster dose, which will increase their immunity by two “log scales”, while indicating that the Triple A regiment will increase an immunity boost by one “log scale.” However, the virologist added that there are individuals who do not want an mRNA booster. Nonetheless, he pointed out that getting a third dose of AstraZeneca is still better than not receiving a booster shot at all. -- © Copyright NNT 2022-02-11 - Aetna offers a range of visa-compliant plans that meet the minimum requirement of medical treatment, including COVID-19, up to THB 3m.

So glad I had an az, followed by Pfizer and then a Moderna booster.

February 12, 20224 yr I am no mathematician but isn’t “log scale” a bit vague? Is it log scale 2 or log scale 10 or something else?Big difference. Is it 2 times vs 4 times or 10 times vs 100 times? Or is it “a little bit more”?

Maybe the good Dr has published the appropriate graph somewhere.

At least among scientists.

It's not any vaccine safety issue that's under consideration, but rather, the effectiveness of the current vaccine regimen that's being trialed on children younger than age 5. They had been looking at a two mini-dose regimen, now they'll be looking at a three-mini dose regimen: "The Food and Drug Administration announced Friday it will not make a decision on whether to authorize a coronavirus vaccine for children younger than 5 until data on a third dose becomes available, a delay that means it could be mid-April at the earliest before shots are available for that age group. ... The FDA and the vaccine makers decided late Thursday night that the companies would not seek emergency authorization for now. A raft of two-shot data had just become available, reinforcing the shots’ safety but showing disappointing effectiveness, according to a person familiar with the situation who spoke on the condition of anonymity to describe discussions among the parties. ... "Pfizer said data on the three-dose regimen could be available in early April, clearing the way for an FDA authorization within days or weeks." https://www.washingtonpost.com/health/2022/02/11/covid-vaccine-young-children-delayed/
