Regular vaccination protects at the population level, which means that infections can hardly or not at all spread. Because of new vaccine developments and the increased knowledge of the duration of protection, it is no longer necessary to give a so-called cocktail every year.
While some vaccines offer long protection (sometimes up to three years), others provide a shorter one. According to the situation, the veterinarian will assess which vaccinations are necessary and when they should be given. This is known as a ‘tailor-made vaccination.’ The annual health check is a good time for this.
