If there is a long lasting but not permanent remedy, people should be RESPONSIBLE (duh) and keep up on the remedy. The third world wishes it had burdens that small!
I’ve had FIVE rubella boosters in the space of about 15 years. Had ZERO titer when tested approximately 1 year after the latest one.
How many boosters would you have me get?
In some people they wear off after a year. Others it’s 2 or 3 or 5 or 10 years. Titers aren’t inexpensive medical procedures. Would you have every single person get a booster of every single vaccine yearly? You just THINK healthcare overhead costs are high now...
