Delta a real bad ass...
British study shows COVID-19 vaccine efficacy wanes under Delta | Reuters
A British public health study has found that protection from either of the two most commonly used COVID-19 vaccines against the now prevalent Delta variant of the coronavirus weakens within three months.
It also found that those who get infected after receiving two shots of either the Pfizer-BioNTech (22UAy.DE) or the AstraZeneca (AZN.L) vaccine may be of greater risk to others than under previous variants of the coronavirus.
Based on more than three million nose and throat swabs taken across Britain, the Oxford University study found that 90 days after a second shot of the Pfizer or Astrazeneca vaccine, their efficacy in preventing infections had slipped to 75% and 61% respectively.
That was down from 85% and 68%, respectively, seen two weeks after a second dose. The decline in efficacy was more pronounced among those aged 35 years and older than those below that age.
.
The researchers would not project how much more the protection would drop over time, but suggested that the efficacy of the two vaccines studied would converge within 4-5 months after the second shot.
Highlighting the increased risk of contagion from the Delta variant, the study also showed that those who do get infected despite being fully vaccinated tend to have a viral load similar to the unvaccinated with an infection, a clear deterioration from when the Alpha variant was still dominant in Britain.
The Oxford findings are in line with an analysis by the U.S. Centers for Disease Control and Prevention (CDC) and come as the U.S. government outlines plans to make COVID-19 vaccine booster shots widely available next month amid a rise in Delta variant infections. It has cited data indicating diminishing protection from the vaccines over time. read more
Israel began administering third Pfizer doses last month to confront a surge in local infections driven by Delta. Several European countries are also expected to begin offering boosters to the elderly and people with weak immune systems.
Pfizer has said its vaccine's efficacy drops over time. Last month AstraZeneca said it was still looking into how long its vaccine's protection lasts and whether a booster dose would be needed to keep up immunity

August 19th, 2021 01:47 PM #30822delta enters cells faster than older variants so it makes copies of itself in less time than older variants --> high viral load in the nose even in vaccinated people

which explains why more children are getting sick now compared to previous waves

August 19th, 2021 05:28 PM #30830Yes that is what im afraid of because frankly speaking our ECQ right now is like MECQ last year and our MECQ is like GCQ last year. Originally Posted by yapoy86

August 19th, 2021 06:09 PM #30832Mukhang happy na sila na we didn't hit the 20,000 cases a day predictions...
ECQ, MECQ only options for Metro Manila: Palace | ABS-CBN News
President Rodrigo Duterte might deliver a national address on Friday to bare the new quarantine levels, "unless he will give authorization to have it announced earlier," Roque said in a press briefing.
Authorities aimed to keep new COVID-19 cases below 20,000 per day with Metro Manila's lockdown, he noted. The health department, he pointed out, confirmed some 11,000 infections on Wednesday.
"We seem to be on track po dahil hindi naman po sumipa beyond the projections," said Roque. "And if we continue with our planned course of action, it will always be below 20,000."
(We seem to be on track because cases did not spike beyond the projections.)
The official also noted that the utilization rate of intensive care units in Metro Manila has gone down to moderate risk.
"The figures are very encouraging as of today," he said.Last edited by Monseratto; August 19th, 2021 at 06:13 PM.

August 19th, 2021 07:10 PM #30835I think it's wrong to focus on just the number of cases per day, that can be easily manipulated, tapos limited pa capacity ng testing. Originally Posted by Monseratto

August 19th, 2021 08:00 PM #30839The biggest reason to keep the Q status ECQ is to not overwhelm the health care system especially now that there is the threat of a mass resignation of HCW due to the inept leadership of the DOH. Originally Posted by Monseratto
