Omicron now

"There is now growing body of literature supporting the conclusion that natural immunity not only confers robust, durable, and high-level protection against COVID-19, but also better than vaccine induced immunity (1-5). Yet most scientific journals, media outlets, self-proclaimed health experts and public policy messaging continue to cast doubt. That doubt has real-world consequences, particularly for resource limited countries. We would like to review available data.

Infection generates immunity. The “SIREN” study in the Lancet addressed the relationships between seropositivity in people with previous COVID-19 infection and subsequent risk of severe acute respiratory syndrome due to SARS-CoV-2 infection over the subsequent 7-12 months (2). Prior infection decreased risk of symptomatic re-infection by 93%. A large cohort study published in JAMA Internal Medicine looked at 3.2 million US patients and showed that the risk of infection was significantly lower (0.3%) in seropositive patients v/s those who are seronegative (3%) (3).

Perhaps even more important to the question of duration of immunity is a recent study that has demonstrated the presence of long-lived memory immune cells in those who have recovered from COVID-19 (4). This implies a prolonged (perhaps years) capacity to respond to new infection with new antibodies.

In contrast to this collective data demonstrating both adequate and long-lasting protection in those who have recovered from COVID-19, the duration of vaccine-induced immunity is not fully known - but breakthrough infections in Israel, Iceland and in the US suggests a few months."

I never heard of bmj, is it a reputable news source like CNN

Omg bahahahaa. Did you really just say that?

So the unvaccinated are a threat? To who?

- Other unvaccinated people don't bltch and moan about it. If an unvaccinated person catches Covid and is severely affected by symptoms, that's on them. If they start bltching about it, then they're just a bltch. They had plenty of chances to get vaccinated.

- Vaccinated people ARE THE ONLY ONES who bltch and moan about the non-vaccinated. YOU HAD YOUR VACCINE. What are you afraid of? If you have an issue with someting, it should be the efficacy of the vaccine. Take your vaccine, get your boosters, and SHUT THE FCUK UP.

This thread is full of unvaccinated bitching and moaning and lying. Who keeps bumping this thread? The unvaccinated. Two of them who keep saying they are done and not replying anymore then come back with more BS.

no its not, i said im not posting any more then i check notifications and someones demanding to know if im vaccinated or not, do we need a vaccine pass to access the lounge now or something? as the other guy said, take your boosters and shut the **** up.

Can't resist when the CEO of Pfizer says we'll be back to normal by spring.

Do you agree with him?

Did you read the article at all. He said it because of new treatments coming.

You didn't even know people could get reinfected, why are you even here discussing this when you don't know basic **** like that?

Throughout the COVID-19 pandemic, there has been much uncertainty about how long immunity lasts after an unvaccinated person is infected with SARS-CoV-2, the virus that causes COVID-19.

Now, scientists at the and the University of North Carolina at Charlotte have an answer: Strong protection following natural infection is short-lived.

"Reinfection can reasonably happen in three months or less," said Jeffrey Townsend of Yale, the study's lead author. "Therefore, those who have been naturally infected should get vaccinated. Previous infection alone can offer very little long-term protection against subsequent infections."

The study, published in the journal , is the first to determine the likelihood of reinfection following natural infection and without vaccination.

The team analyzed known reinfection and immunological data from the close viral relatives of SARS-CoV-2 that cause common colds, along with immunological data from SARS-CoV-1 and Middle East Respiratory Syndrome. Leveraging evolutionary principles, the team was able to model the risk of COVID-19 reinfection over time.

Reinfections can and have happened even shortly after recovery, the researchers said. And they will become increasingly common as immunity wanes and new SARS-CoV-2 variants arise.

"We tend to think about immunity as being immune or not immune, but our study cautions that instead we should be more focused on the risk of reinfection through time," said Alex Dornburg of the University of North Carolina at Charlotte, who co-led the study. "As new variants arise, previous immune responses become less effective at combating the virus. Those who were naturally infected early in the pandemic are increasingly likely to become reinfected in the near future."

The team's model reveals striking reinfection similarities over time between SARS-CoV-2 and endemic coronaviruses.

"Just like common colds, from one year to the next you may get reinfected with the same virus," Townsend said. "The difference is that, during its emergence in this pandemic, COVID-19 has proven to be much more deadly."

A hallmark of the modern world is the evolution of new threats to human health, Townsend said. Evolutionary biology -- which provided the theoretical foundations for these analyses -- is traditionally considered a historical discipline.

"However, our findings underscore its important role in informing decision-making, and provide a crucial steppingstone to knowledge of our prospects of resistance to SARS-CoV-2 reinfection," he said.
