Heap o' Covid-19 Wed Aug 11, 2021

On July 31, a Carnival cruise ship departed from Galveston, Texas; every guest and every staff member was fully vaccinated. They’ve now got infected people aboard. Hmmm.

Japanese study mentioned above found the mRNA vaccines have a antibody "half-life" of about 68 days. After 198 days the level of neutralizing antibodies is down to nil. The latest Israeli data has the infection efficacy down to 20% (with confidence interval reaching 0%) for those vaccinated in Feb.

Now, sterilizing vs non-sterilizing vaccines/immunity. I think we're all pretty much up to speed on that. It is clear these spike protein only vaccines are non-sterilizing and cannot prevent infection and transmission.

Now, note that the protection against *severe disease* is still higher than 20%. How does this work, you may wonder. How can a non-sterilizing vaccines that allows for infection and transmission still reduce more severe disease.

There is no worthwhile "memory immunity" (T-cell) induced by these spike only vaccines. You need N-protein recognition (which natural immunity provides in spades) to get sterilizing, "point of entry"/mucoscal immunity to this virus.

Now, say a vaccinated person with low antibody titers gets infected. There is still some "spike memory" there, which, when enough cells get infected and the spike protein is floating around, will be recalled to produce more anti-spike activity.

This is the mechanism via which it still maintains higher efficacy against severe disease. And this is also the mechanism to put natural selection pressure on the virus to mutate it's spike protein to escape that immune response.

This is why using a non-sterilizing vaccine in the middle of a mass outbreak of the disease you're fighting is weapons-grade stupid. Those who do this should be taken out and shot. It's that stupid.

When you have an active outbreak of something, by God, you only want to use sterilizing vaccines or nothing at all.
