The world await nasal vaccine.
Also there is a slight increase of vaccination rate in US after Novavax entry.
Rest of story you can think yourselves.

[WhatDoYouThink?]

if each dose has 95% efficacy, 4 doses shd be almost 100%? or at least 99.999%? if still kena means bad luck loh

99.999375% He is the unlucky one for those who are twice vaccinated and twice boostered.

[WhatDoYouThink?]

so even a cheap and lousy one with an efficacy of only 70%, still can achieve 99% after 4 doses. so what's the big fuss and all the quarrels?
