Now, let me ask this question.....do we continuely vaccinate ourselves as adults???? No, we don't....so why do we continue to vaccinate our adult animals annually.
The big "anti-vaccine" hype in people is going to cause havoc in about 10 years, when all these unvaccinated kiddies who rode on the wave of herd immunity start getting pregnant and getting infected while they're carrying their children. THOSE babies are the ones that are going to really suffer. It's scary and so very sad. Their poor parents never got protected, because of the good but erroneous intentions of THEIR parents. Birth defects are going to absolutely go through the roof, almost all of them preventable. The smart kids who haven't been vaccinated today will get themselves vaccinated before they start having kids of their own.
