Immunity to the Coronavirus May Persist for Years, Scientists Find
- nikolay 5y agoUtter nonsense! Why is SARS-CoV-2 different than other coronaviruses, which cause a big toll on the whole planet each year for millennia? Or why we are not immune to the flu for life? Too much wishful thinking nowadays!
- simtel20 5y agoMy recollection is that you are probably immune to the flu you had 3 years ago. You are not immune to the flu as it has mutated this year. Covid may or may not be similar. That's why scientists study it and report on aspects like this.
- nikolay 5y agoThat's based on very shaky assumptions. Although coronaviruses are not as rapidly mutating into new strains as the influenza viruses, RNA viruses compared to DNA viruses mutate quite a lot. To deceive people that they have lifetime immunity is both unscientific and irresponsible - I already know people who ignore all kinds of protective measure because they've had it last winter and assume they are immune for life. We yet have to see that and go beyond pure hypothetical speculations like this one! The coronaviruses are responsible for 20-30% of the common cold, which sickens hundreds of millions of people each year.
- AndrewBissell 5y agoInfluenza is not a coronavirus. The closest analog we have to SARS-CoV-2 in the wild is SARS-CoV-1, where continuing immune response has been well established even in those infected during the initial 2003 outbreak.
- nikolay 5y agoAssuming much? When did I mention influenza?!
- AndrewBissell 5y ago> Or why we are not immune to the flu for life?
- nikolay 5y agoYikes! Sorry, the only reason I mentioned it is that it's an RNA virus like the flu. Is there a study showing immunity to SARS-CoV-2 in people who had SARS-CoV? Can you point to a peer-reviewed study showing lasting immunity to SARS-CoV?
- AndrewBissell 5y ago> But T cell studies allow for a substantially different, more optimistic, interpretation. In the Singapore study, for example, SARS-CoV-1 reactive T cells were found in SARS patients 17 years after infection. “Our findings also raise the possibility that long lasting T cells generated after infection with related viruses may be able to protect against, or modify the pathology caused by, infection with SARS-CoV-2,” the investigators wrote. https://www.bmj.com/content/370/bmj.m3563#ref-8 https://www.bmj.com/content/370/bmj.m3563#ref-8
- nikolay 5y agoIf they are so certain about their statement, why didn't they try re-infecting them?
- AndrewBissell 5y agoIf the vaccine manufacturers are so confident in their effectiveness, why didn't they run challenge trials?
