There is extensive data and decades of studies, repeatedly reviewed, and the link between vaccines and autism has been definitively disproven.
Some of us are less healthy—just look at rising rates of overweight and obesity, which bring many secondary health issues. But the cause isn’t vaccines, WiFi, or 5G. It’s largely due to diet and lack of exercise. And no, there are no quick fixes for this.
In part 1 I discussed the incorrect statements, based on misunderstanding how vaccines work, what they are, that they are preventative, that there is no precise time, that all have been tested in clinical trials, and that they should be given to healthy children. Why them?
He claims it needs to be based on "good science." No vaccine offered is not based on good science. They are all based on detailed knowledge of how our immune system and its cells work, and they were all tested in pre-clinical models, clinical trials, and post-authorisation.
Though it may feel bleak, policy is still to be made, and we can influence it. Today brings frustration, even grief, but tomorrow is another chance. Don’t let anger win; instead, let’s support those who need protection and focus on constructive action.
During acute inflammation, many molecules are upregulated at the surface of cells. These include many of the same markers, such as CTLA-4 and PD-1. That in itself does not signal "exhaustion".
2) Together with 1), mutating to enhance infection changes. These include most respiratory viruses. They are generating variants selected on the basis of reduced neutralising antibody binding.
An antigen is anything the immune system can recognise. However, I will limit this to proteins, small pieces of which are called peptides, the specific amino acid sequence recognised by an antibody or T cell is an epitope.
These wrong assertions are based on this study
Someone much better at crunching these numbers, @MichaelSFuhrer, made this graph, based on science and reasonable assumptions. 
It concerns the work of Charles Richet, who was not a nice man. In 1913, he won a Nobel prize for his work on severe allergic reactions (a type-2 immune response), before we understood much of immunology. He did not receive it for finding out how to poison people! 
Any infection (trauma) can, and often should, cause an inflammatory response. Some of the cells and soluble mediators act locally, but others systemically. This allows many organs to work together to combat the invader. e.g. your liver will get signals to increase body temp.
