You can apply the same logic you used to getting a second vaccine, and a booster, and another booster, and, it looks like, yet another booster.
"Why should I have another vaccine, when I've already had one?" Or, "Why should I have a vaccine, when I've got natural immunity from a previous infection?"
In reality, though, previous infections, vaccines, and boosters still fail to confer immunity against continued infections and variants.
It remains to be seen if the vaccine, anti-viral, and polyclonal antibodies that Humanigen wants to administer are proprietary formulations to the company, or are already commercialized. But due to the UN-waning efficacy of lenz, if the company's second drug can improve efficacy even higher, they may have developed a genuine vaccine compound.
