@MichaelSFuhrer @taipan168 Nasal vax likely has significant advantage in terms of distribution. People don't really like needles (but many tolerate), giving the shot requires some specialized skill, etc. Take a puff on an inhaler, whatever. I'll take a puff every month if it'll help me, no biggie.
@MichaelSFuhrer @taipan168 Nasal vax 在分布方面可能具有显着优势。人们并不真正喜欢针头（但许多人容忍），打针需要一些专业技能，等等。用吸入器吸一口，无论如何。如果对我有帮助，我每个月都会吸一口，没什么大不了的。
