Walker88 Posted June 19, 2020 Share Posted June 19, 2020 https://www.nature.com/articles/s41591-020-0965-6 According to this article, based on a Chinese study of those infected earliest with Covid-19, immunity gained via antibodies may only last 2-3 months. The figure for SARS is 1 year and for MERS 34 months. If this initial research is correct, the idea of 'herd immunity' is almost pointless, and even a vaccine may be of limited short term value, since the purpose of a vaccine is to have the body produce antibodies. The negative implications of this early research are staggering. 2 Link to comment Share on other sites More sharing options...

sirineou Posted June 19, 2020 Share Posted June 19, 2020 I think the longest Covid 19 has survived outside a host it is 17 days, and on the average two or three days. So if immunization denied covid 19 hosts for Three months......... Link to comment Share on other sites More sharing options...
bkk6060 Posted June 19, 2020 Share Posted June 19, 2020 Maybe this is will be motivating. Sounds like the older fat, obese, diabetic, smoker, alcoholics should consider changing their lifestyle if they want to have a better chance to live longer in the future. 1 1 Link to comment Share on other sites More sharing options...

Needs a major vaccine update every 3 months ! Edited June 19, 2020 by Dumbastheycome additional word update 1 2 Link to comment Share on other sites More sharing options...

Motivate us to contract the disease to escape judgemental narcissists. Edited June 19, 2020 by frantick Link to comment Share on other sites More sharing options...

I think you're forgetting about something here, something important. Google this 'SARS-COV-2 specific T cells'. They're not antibodies and don't show up in an 'antibody test' but rest assured that they exist. Sometimes they're referred to as 'memory T cells' and they're part of a system that provides longer term immunity. I will add that this is the part of the puzzle which a lot of people seem to think provides 'cross reactive' immunity based on previous infection to some other similar virus, like one of the common cold coronaviruses. These COVID specific T cells have been found in older blood samples pre-dating the pandemic by years. 3 Link to comment Share on other sites More sharing options...

Which is why there won't be big second waves anymore, just smaller clusters here and there, where the virus has not been already. Link to comment Share on other sites More sharing options...

Good point .... and the report says that people with no symptoms had a weak antibody response, but that is probably because they were already immune to a closely related virus. And people who had serious symptoms (probably because they had no prior exposure to a similar coronavirus) had a stronger antibody response. Immunity is a complex area, and the report authors must have known that, but everyone has a vested interest in COVID-19 propaganda. Researches want more funding, news media want more clicks to drive advertising revenue, politicians want justification for their panicky over reactions, drug companies want their shares prices to rise, scared people want evidence that their fears were founded. Flu is just as complex, potentially more deadly, TB kills more people, but they are not fashionable diseases. Link to comment Share on other sites More sharing options...
