> When I got vaccinated for various diseases, it gave long term immunity, not 4 doses over months to lessen the symptoms. Which works for some diseases. Others are only effective for shorter periods of time and/or against specific variants. The flu vaccine should be a familiar example to most people, needing periodic refreshers that are most effective against certain variants and not others. It's also worth noting that the diseases that are treated as a "one and done" are generally those where you're unlikely to be exposed in day to day life for a variety of reasons. |
