I do not see this being the case. I highly doubt the effectiveness of every vaccine ever produced, since I know a lot of people that yearly vaccinate for flu, many of which get sick and even the graphs showing people infected by years isn't doing vaccines any favors, since I think the old diseases were dying out either way anyways, Same for these ludicrous vaccines for little children, my neighbour's kid got terribly sick 2 days after vaccination with extremely high body temperature which lasted for couple of days. He seems to be fine now, but my guess here is that they have a lot of confidence in 5G, so no need really to create some deadly pathogens since the electromagnetic furnace is going to do its job either ways, or at least they hope. I do not doubt there are reserve plans in these fellas' pockets, but I think new 'deadly' plague is highly unlikely. I still wish sheeple will wake up before this COVID-19 vaccine so this corporate-fascist system fall apart before plan B.
