On 19th Sept 2022 POTUS (President of the United States) declared on the 60minutes show from Detroit that the pandemic is over although "we are still doing a lot of work on Covid. If you notice, no one is wearing masks - everyone is in pretty good shape"

Dr Campbell looks at the Emergency Use Authorisations dated 31st Aug 2022 which says that vaccines for the original strain + BA.4 + BA.5 variants are all allowed in the same jab.
6th para first line says that the authorities "based its decision on the totality of available evidence", and they go on to say they used extensive safety and effectiveness data.
Shockingly, at para 15 beginning "For each of the bivalent Covid 19......." it says that they based the safety data for jabs on a component of the original strain and a component of strain BA.1. (not BA.4 or BA.5). They say that the strains are similar.
Campbell poses the question that maybe this amounts to taking un-necessary measures (risk?) now that the pandemic is over. He notes that Biden administration has already ordered 170million doses.
Science magazine is a peer reviewed publication and looked at data supplied by Pfizer and Moderna. If you scroll down the page to heading "What sort of data have the companies collected" you will see that human data only relates to strain BA.1. For BA.4 / BA.5 boosters, they only submitted animal data on 8 mice which has not been released publicly.The 8 mice were given the BA.4 / BA.5 booster and showed increased response to all variants and so now it is authorized for humans.
