>>12688814A lot of what's cited there is not too broadly applicable, and a lot of the conclusions are taken out of context. Just as an example, it cites an article that says mice who were immunized were more likely to die.
If you look at the data, what you see is that if you immunize mice against a specific strain of influenza, and then expose it to a different "heterosubtype", then the immunized mice are more likely to die than those who were exposed to the first virus itself (the one the immunization was made against).
This is a very specific case targeting a very specific sequence of events in a very specific type of virus. It is not likely to be applicable in the real world based on the viruses we know to be seasonal like influenza. The article authors themselves state that this should not cause us pause with regards to immunizing children and adults, but rather that as we improve vaccines we can further reduce the risk of these types of rare incidences by targeting the various heterosubtypes.
