Very good article. Although "caution ...[was] indicated," that 2012 research was superseded in 2020 with other approaches and numerous trials that included studies of the hypersensitivity. As one develops antibodies to certain viruses - including the seasonal flu - one is less likely to suffer the consequences of a virus outbreak. A remaning question might be: will people become dependent on seasonal flu jabs? In any event, reducing the spread of the virus so that people can return to work is another benefit of this widely tested vaccine (even if it's in conjunction with masks and social distancing). And now it seems 100 million in the US have had the first jab. Are they fucked? Not likely.
