Omicron highlights fading hope of herd immunity from COVID-19
The Omicron variant, which is spreading far faster than previous versions of the coronavirus, is not likely to help countries achieve so-called herd immunity against COVID-19, leading disease experts say.
From the earliest days of the pandemic, public health officials have expressed hope that it was possible to achieve herd immunity against COVID-19, as long as a high enough percentage of the population was vaccinated or infected with the virus.Those hopes dimmed as the coronavirus mutated into new variants in quick succession over the past year, enabling it to reinfect people who were vaccinated or had previously contracted COVID-19.

CTV doesn't want to give up the panic porn Thank you for yet another long winded article that confuses more than clarifies. And of course there is NO END IN SITE. Truly sick of CTV, CBC and Global so called reporting. Why fading ? The original Covid is dying off and turning into a common flu. That's why poeple are getting moore infected. This is good news !
If the antivaccers would get the shot, the spread would stop eventually. If not, we will be on this carousel for a while yet. Instead of lockdowns, restrict the unvaccinated. Ask for proof of Vaccination prior to entering any public place. Both gov’t and private establishments. No more mask and vaccine bullshit
What? It’s over ! Why do you persist in negative headlines of foreboding doom and gloom? The media,big pharma and govt want to keep this going as long as they can ! Stop it ! It’s over in England , it’s over in US! Focus on the shitty state of our hospitals ! IvisonJ How would you feel if someone you don't know steals your house in the evening and says I am an Israeli? That's happening on Palestians.
We can't beat it but we can protect ourselves against serious outcomes by being vaccinated or having recovered from Covid-19. So we should drop all restrictions and just let it rip. AMemphys Do you know what hers immunity is? If so please explain how it is achieved. Careful with the lies.
Incidental COVID-19 transmissions to hospital patients creates strain for Alberta health-care workersThe province of Alberta is beginning to differentiate its statistics on patients hospitalized with COVID-19 and those where it is unclear if the virus contributed to their admission. Imagine still enforcing proof of vaccination when the data clearly shows the vaccine has zero effect on getting or transmitting the virus. But then again, it does make sense when you consider it has never been about public health. Also rehire unvaccinated doctors
So we spend 1/2 a trillion in debt over 2 years, countless lockdowns, tens OS thousands of bankruptcies, complete disdain for charter rights, and we are in a worse place than ever before. There is no evidence that anything worked. We have nothing to show for all of this. Of course CTV prefers a society like the one in the photo where police wander the crowds randomly asking people to show their papers. The pandemic ends when we stop complying, not a moment sooner.
Now you are just looking thirsty Game over. Media/government loses. We know the truth. Takes a few years to achieve ...won't happen in a year in two. Shut up ctv… it’s over the gig is up

COVID-19 linked to death of four-year-old girl in Quebec CityAccording to Quebec Health Department data, that was the first child under 10 to die of the disease in the province inky_mark Wow imagine that, they start vaccinating kids and then they start dying of Covid! So tired of reading this shit. When are people going wake up and just stop. How many kids does this have to happen to.
CHICAGO -- The Omicron variant, which is spreading far faster than previous versions of the coronavirus, is not likely to help countries achieve so-called herd immunity against COVID-19, in which enough people become immune to the virus that it can no longer spread, leading disease experts say.Alberta Chief Medical Officer of Health Dr.Should we be using rapid tests in B..
From the earliest days of the pandemic, public health officials have expressed hope that it was possible to achieve herd immunity against COVID-19, as long as a high enough percentage of the population was vaccinated or infected with the virus. Those hopes dimmed as the coronavirus mutated into new variants in quick succession over the past year, enabling it to reinfect people who were vaccinated or had previously contracted COVID-19., 52 per cent of non-ICU admissions were due to COVID-19 infections and 48 per cent were either incidental, or it was unclear whether the virus contributed. Newsletter sign-up: Get The COVID-19 Brief sent to your inbox Some health officials have revived the possibility of herd immunity since Omicron emerged late last year. Brian Conway offers his advice. The fact that the variant spreads so quickly and causes milder illness might soon expose enough people, in a less harmful way, to the SARS-COV-2 virus and provide that protection, they argue. As of the latest update on Tuesday, there are 1,007 Albertans in hospital with COVID-19, including 94 in ICU. Disease experts note, however, that Omicron’s transmissibility is aided by the fact that this variant is even better than its predecessors at infecting people who were vaccinated or had a prior infection.
That adds to evidence that the coronavirus will continue to find ways to break through our immune defenses, they said. Dr. JPG COVID-19 measures on Tuesday. “Reaching a theoretical threshold beyond which transmission will cease is probably unrealistic given the experience we have had in the pandemic,” Dr. Olivier le Polain, an epidemiologist with the World Health Organization (WHO), told Reuters. “We’re seeing people coming to the emergency department with other problems, a broken ankle for example, and they may also tell us that their throat is a bit scratchy so we’re then obligated to do a PCR test,” he said. That is not to say that prior immunity offers no benefit. Dr. Instead of herd immunity, many experts interviewed by Reuters said there was growing evidence that vaccines and prior infection would help boost population immunity against COVID-19, which makes the disease less serious for those who are infected, or become reinfected.” Lang adds that there are still people who are generally unvaccinated or immunosuppressed who are coming in with COVID in their lungs and require oxygen for a few days.
“As long as population immunity holds with this variant and future variants, we'll be fortunate and the disease will be manageable,” said Dr. David Heymann, a professor of infectious disease epidemiology at the London School of Hygiene and Tropical Medicine. Doctors working in the emergency department also tell CTV News that the risk of becoming infected in hospital is very low. Henry has said you can have private indoor gatherings with up to 10 guests or one other household. NOT LIKE MEASLES Current COVID-19 vaccines were primarily designed to prevent severe disease and death rather than infection. But clinical trial results in late 2020 showing that two of the vaccines had more than 90% efficacy against the disease initially sparked hope that the virus could be largely contained by widespread vaccination, similar to the way measles has been curbed by inoculation. “Patients who need a hospital bed for whatever reason, might not have a place to go because there are limited beds upstairs and much of the units are closed because of staffing shortages or COVID outbreaks,” Lang said. With SARS-CoV-2, two factors have since undermined that picture, said Marc Lipsitch, an epidemiologist at Harvard T. You should bring a good, warm sweater so doors and windows can be kept open.
H.” COULD COVID-19 INFECTIONS IN HOSPITAL LEAD TO MORE SERIOUS PATIENT OUTCOMES? Calgary public health physician Dr. Chan School of Public Health. "The first is that immunity, especially to infection, which is the important kind of immunity, wanes quite quickly, at least from the vaccines that we have right now," he said. However, questions still remain as to whether or not the virus could be a driver of worsening symptoms for those who were not hospitalized for COVID in the first place and were diagnosed while receiving care by doctors. Too many people are wearing them under their chin or not wearing them at all in situations where they should. The second is that the virus can quickly mutate in a way that enables it to elude protection from vaccination or prior infection - even when immunity has not waned. "It changes the game when vaccinated people can still shed virus and infect other people," said Dr. “Patients or staff getting COVID in hospital is always a really bad thing because people at the hospital are at higher risk, it also really wreaks havoc on the ability of hospital units to admit patients and on staffing, which is going to be one of the biggest challenges every province, including ours, is facing right now with Omicron.
David Wohl, an infectious disease specialist at the University of North Carolina at Chapel Hill School of Medicine. So at the very least, lets achieve that practical standard. He cautioned against assuming that infection with Omicron would increase protection, especially against the next variant that might arise.. "Just because you had Omicron, maybe that protects you from getting Omicron again, maybe," Wohl said. Vaccines in development that provide immunity against future variants or even multiple types of coronaviruses could change that, said Pasi Penttinen, the top influenza expert at the European Centre for Disease Prevention and Control, but it will take time. Q: Should we be using rapid tests in B. Still, the hope for herd immunity as a ticket back to normal life is hard to shake.
"These things were in the media: 'We’ll reach herd immunity when 60% of the population are vaccinated.' It didn't happen. They are very useful, especially in asymptomatic people, so having rapid tests will interrupt transmission networks more effectively and if you are going to an indoor gathering it would allow us to exclude people who are infected and didn’t know it. Then for 80%. Again, it didn't happen,” Francois Balloux, professor of computational systems biology at University College London, told Reuters. “As horrible as it sounds, I think we have to prepare ourselves to the fact that the vast majority, essentially everyone, will get exposed to SARS-CoV-2," he said. Should B.
Global health experts expect that the coronavirus will ultimately become endemic, circulating persistently in the population and causing sporadic surges. The emergence of Omicron, however, has raised questions about exactly when that might happen. “We will get there," said the WHO's le Polain, "but we are not there at the moment. Explain to me clearly why policy is evolving differently in different provinces.” RELATED IMAGES .
