Puppies are typically vaccinated at eight and 10 weeks, kittens at nine and 12 weeks, with an initial course of two injections. Your young pet should then be given a booster 12 months after their first vaccination.
Without antibiotics, you may be contagious for two or three weeks; most people who take them, however, are no longer contagious 24 hours after the start of treatment. Other people also experience relief from the symptoms of strep once they've started taking antibiotics.
In those individuals who develop strep throat, the symptoms usually begin between 1 to 4 days after initially acquiring the infection (incubation period).
