What is the main reason that inhaled vaccines are not in use today for flu for example? Is there some new technological breakthrough for delivery that was needed?
- kwantam 5y agoThey are! Inhaled flu vaccines are generally live attenuated virus, which isn't recommended for everyone but is perfectly effective for a large segment of the population: https://www.cdc.gov/flu/prevent/nasalspray.htm https://www.cdc.gov/flu/prevent/nasalspray.htm
- consumer451 5y agoFrom a lay person's point of view, I am trying to imagine if there would be significant extra mass required to distribute a billion inhalable vs injectable vaccines. It seems like there would be additional mass and volume. Could that be one reason?
