I am not essentially anti-vaccine or Gates in terms of his work in IT development (although I wouldn't trust him or the WHO as far as I could throw them or any other large corporation for that matter especially the Pharma industry).
There are many more like this but most credible information has disappeared off ' loose searches ' (along with the conspiracy shyte). Google and YT is now the Ministry of Truth and Bill Gates always was and always will be a demi-god.

Also, this interview with Kennedy Jnr may be of interest (if you keep an open mind). His uncle once spoke about secrecy ( a while before he was silenced )
