Our essay on vaccines that give humans immune responses superior to those generated in response to infection, now including #SARSCoV2
@scrippsresearch @ScrippsRTI w/ Dennis Burton
To elaborate on the concept of superhuman vaccine immunity:
Each of the 3 examples in our piece are for different reasons.
1. HPV—best, since the human response is weak
2. Tetanus—small amounts of toxin don't elicit strong response)
3. H Flu—the bacterium is sugar coated

This is different from vaccine efficacy.
Take measles. The natural human response to infection provides durable efficacy but the vaccine requires multiple shots and is without lifelong protection. 3/
Superhuman vaccine = superior to typical human response to natural infection
The #SARSCoV2 neutralizing antibody response to mRNA vaccines has exceeded that of many convalescent patients by orders of magnitude

The natural human response to #COVID19 infection leaves many patients without a full and/or durable immune response, as nicely depicted (G=IgG, B=B cells, 4=CD4, 8=CD8, A=IgA)

Several #SARSCoV2 reinfections have been documented in patients without a sufficient IgG antibody response to the primary infection bnonews.com/index.php/2020… 6/
There are still many unknowns about the mRNA (and other platform) #SARSCoV2 vaccines with respect to durability, sterilization immunity (that would prevent transmission) and the role of T cells. 7/
In sum, the results to date suggest #SARSCoV2's spike protein lays the foundation for a potent vaccine-induced immune response that will turn out to be superior to that derived from natural infections. 8/
I recently spoke to @DrPaulOffit about the concept of a superhuman vaccine immune response

He highlighted the #SARSCoV2 inhibition of our interferon response and this point👇
And cited the 3 prototypic examples
