How many seconds is a vaccine?

Answer 1

A vaccine is a medicine for immunity and does not have "seconds".

If you mean how many seconds does it take for the vaccine to be administered, then the injection of a vaccine usually only takes 5-10 seconds to put the vaccine into your body with a needle since the amount of vaccine needed is so small. If the vaccine is available in a nasal mist, the inhalation of a nasal mist takes as long as it takes for you to sniff.

If you mean how long will the immunity last before you need a booster vaccination, you should check with your doctor about the type of vaccine you are getting (e.g. influenza, bacterial pneumonia, etc.). Depending on your age and the type of vaccine, some vaccinations need boosters every so often. Your doctor can tell you how long the one you are getting lasts.
