AstraZeneca puts Covid-19 vaccine trails on temporary hold after recipients 'potentially unexplained illness'
“Is the cure worse than the cause?”
AstraZeneca's vaccine, known as AZD1222, relies on chimpanzee adenoviruses that have been modified to carry coronavirus genes and deliver them into human cells
Although the adenovirus is generally thought to be harmless, the coronavirus components of the vaccine are intended to incite a protective immune response that would be roused again should the actual coronavirus try to infect a vaccinated individual
Adenoviruses, however, can sometimes trigger their own immune responses, which could harm the patient without generating the intended form of protection
Sounds like a good thing right?
...
Enhanced immune response, known as pathenogenic priming, is when a vaccine produces a good antibody response in a subject but when they are later exposed to the wild virus they have an increased risk of death than those who have not been vaccinated
