Why was this flagged? It's just a study?
While I support vaccines in general, I also see that in this specific case, a highly experimental vaccine with weak effects (doesn't prevent COVID-19 infection) and possible side effects needs to be discussed.
It doesn't take a conspiracy theorist to imagine that pharmaceutical companies would have a vested interest in promoting a vaccine that needs to be constantly updated (I remember talks of dose #3 and #4 and so on).
