i wish it was permanent :/ probably just 6 months though as corona infected are also only 6 months immune. fever side effects or soreness or tiredness though are signs that your immune system reacts and the vaccine is working. so if you are terminally ill already, these side effects might be too much, but if you are terminally ill you would die either way right?

and any exposure to a new disease or vaccines, or foreign bodies is a transformation of your immune system?
