Reply To: Is the 27th booster effective?

I looked up again history of withdrawn vaccines and medicines. There are quiet a number of medicines that were withdrawn after multiple years of use as long-term complications were discovered. In contrast, the only problems that ever existed with vaccines were either near-term that were discovered by observing early tests within a year, or manufacturing problems. During last several decades, there were several times when a vaccine was withdrawn or stopped, but later analysis showed that there was no problem after all.
