RE:Single dose of Johnson & Johnson vaccine is 66% effective !!Johnson & Johnson's single-dose vaccine is 66 per cent effective at protecting against COVID-19....that's great example of a late comer to market that has managed to differentiate their product from the others even though it's only 66% effective......... Too bad Vaxil can't even get to clinical trials after huge failure to produce protective antibodies duing USAMRIID experiment ...shame, first Merck and now Vaxil ....at least they have their 10 year old cancer orphan status drug ......I guess that's all we got at this point .....so what is the status of iMmucin anyways ??? Are they allowed to sell it or trial it ???
