I m a bit of a conspiracy theorist but I can't help think the government's are only shown what the big boys have to offer, pfizer, astra zenica etc. The likes of rce either get bought out or ignored it seems judging by recent WHO search for companies that can fight anti bacterial resistance. Searching for a long time yet apparently no idea rce exist? I'm sure this will be same, a big pharma will have an awesome solution for a few billion dollars that is perfectly safe and doesn't cause blood clots, but maybe it does, but anyway its an acceptable risk.
