I expect the cases are nearly all vaccinated. It will be interesting to see the results of Omicron on the unvaccinated in western countries.
12) Quantifying the risk of SARS‐CoV‐2 reinfection over time, Murchu, 2021 “Eleven large cohort studies were identified that estimated the risk of SARS‐CoV‐2 reinfection over time, including three that enrolled healthcare workers and two that enrolled residents and staff of elderly care homes. “Across studies, the total number of PCR‐positive or antibody‐positive participants at baseline was 615,777, and the maximum duration of follow‐up was more than 10 months in three studies. “Reinfection was an uncommon event (absolute rate 0%–1.1%), with no study reporting an increase in the risk of reinfection over time.”
Omicron, you expect, are nearly all jabbed? That's a hell of a note. The worst part of 15 days to flatten the curve is the first 2 Years.
Early studies suggest omicron is formidable — but not unstoppable The variant erodes a key line of defense from vaccines, but boosters can help restore protection The data is preliminary, and leaves some of the most urgent questions about omicron — including how it will behave in the real world outside of laboratories — unanswered. Collectively, the new research suggests omicron can dodge some of the most important immune defenses triggered by vaccines, but only partially. As expected, virus-blocking antibodies generated by two shots of the Pfizer-BioNTech vaccine dropped steeply in the face of omicron’s many mutations. But building a higher wall of immune protection appeared to restore protective levels of antibodies. Booster shots are one way to do that. The research also suggests that people who have been infected with the coronavirus and then get the two-shot regimen generate sufficient antibodies to keep omicron at bay. “With omicron, with these data over the past 24 hours, I’d say it’s unequivocal that boosting for the winter is important,” said Shane Crotty, an immunologist at La Jolla Institute for Immunology who was not involved in the studies released this week. “For the general public, the good news is the boosters are going to work, full stop.” __________________ I'll be keeping an eye on whether "the boosters will work" turns out to be more crowd control. Let's see if they start pushing a new Omicron vaccine in a few months.
Omicron may require fourth vaccine dose sooner than expected, Pfizer says Albert Bourla, Pfizer’s chief executive, had projected that a fourth dose might be needed 12 months after a third shot. But he said on CNBC’s “Squawk Box” that the timeline mightneed to be moved up. One of the company’s top scientists recently said a fourth shot — possibly one targeting omicron — is likely to be necessary. ___________ aha!
This is not surprising. When Pfizer and companies were originally developing the current generation of Covid vaccines they stated a booster would be needed every 12 months. Well it turned out the first booster was needed at 6 to 8 months. It is not surprising the 4th booster would be needed sooner than 12 months after the third one. They are working on a universal permanent vaccine for coronavirus -- but this still at least 5 years out. Locally Duke University is involved in this research.
