Priming of the cellular immune system is long lasting.
The antibodies generated by the “boosters” are not protective and do not prevent transmission. The reason they like to use antibodies to measure “protection” is because they are easy to measure.
Measuring T cell encoding against SARS CoV 2 is possible but not practical on a large scale.
How can that be done? What kind of test is it?
I have some health issues that cause me to be very reticent to inject ANYTHING into my body because of the likelihood of a bad reaction. I've had reactions to enough vaccines in the past, tetanus and the pneumonia vaccines, to cause me to decide against anything that is not literally life saving.
I will not take the risk of taking a vaccine that could cause a life threatening allergic reaction.
I've had Covid twice and it was no worse than other flus or colds I've had in the past, but would like to be able to have some test results showing the long term immunity.
