The article describes a potential new method develop immunity through an universal vaccine. The article misses to explain how normal vaccines work; vaccines normally introduce a foreign body that can be part of a pathogen allowing the immune system to recognise it and respond faster, also preventing more virulent responses. Normally, these elements are tailored to a particular pathogen, which contrast with the new vaccine which pre-emptively activates the immune system. The article doesn't show any numbers from the test-groups but they properly reflect the pros and cons of this new method. The title of the article is a bit misleading, giving the impression it may be already tested in humans, whereas it is in the early stages of development.
