This falls under the bad news category. One thing to note, it
has taken a long time for a vaccine resistant strain to show up.
Vaccines don’t act as selection pressures in the same manner
that antibiotics and antivirals do. Antibiotics act as immediate
threats to survival, selecting for the mutants in a population
that can survive in the presence of an antibiotic. Vaccines
functionally increase the number of infectious particles needed
to overcome immunity. Think of it this way, once you start a
course of antibiotics, you already have billions upon billions
of pertussis bacteria playing pinochle in your snout, pleural
cavity (where your lungs are) and elsewhere, and you have
probably exposed everybody that lives with you and a majority of
people that work or go to school with you. If they have not been
vaccinated, or have not received a booster in the last decade or

has strong immunity from the vaccine, only the bacteria that are
already mutated i
