So Much for Herd Immunity :(

The researchers said they were surprised to find that the antibody “titer” value in about a third of the patients was less than 500, a level that might be too low to provide protection.

“About 30 per cent of patients failed to develop high titers of neutralising antibodies after Covid-19 infection. However, the disease duration of these patients compared to others was similar," they said.

The team also found that antibody levels rose with age, with people in the 60-85 age group displaying more than three times the amount of antibodies as people in the 15-39 age group.

The low amounts of antibodies could affect herd immunity, resistance to the disease among the general population to stop its spread.

 

gonna need a vaccine, its looking like herd immunity will not work. begs the question is a vaccine even possible if the body cannot produce large quantities of antibodies?

Just like many of us have lost friends and family to cancer,  a year from now we will know people who perish from the Chinese Civid19.

Ok, so the antibodies don't last long. The CEO of Centivax guessed 8-10 weeks, how long has the lockdown there lasted now?

 

Wuhan was 23rd January. 11 weeks ago. Those people were in hospital for how long? Could match.

 

Here's the study: https://www.medrxiv.org/content/10.1101/2020.03.30.20047365v1

 

Looks like that was just after a couple of weeks in the hospital. Not enough time for the antibodies to disappear if they were there. Not good news and not really the data I was hoping to find. Still no good data on how long the "immunity" could last.

 

Here's another kicker to the danglies:

We observed that elderly patients were more likely to induce higher titers of NAbs than younger patients. 

 

So the young are more likely to become carriers again. Ugh. This really is a boomer butcher.
