Wasn’t the modern anti-vaxx movement started by a British Doctor who published false information about the MMR vaccine and was struck off in the UK? He relocated to America where the anti-establishment and distrust of the government culture was a perfect platform for his lies. Not saying Americans are more impressionable [emoji13]
I have found with covid conspiracy theories, a lot of the sources come from American doctors, or websites now. There is a retired virologist called Mike Yeadon who has found fame spreading misinformation about the vaccines here and he is trusted by anti-vaxxers because he’s ‘a doctor’ and once worked for ‘Pfizer’ until 2011, although he didn’t work with vaccines whilst there! lol Still an expert though [emoji2359]
