how is a vaccine produced

Answers

Answered by kale84177

Answer:

Vaccines are made by taking viruses or bacteria and weakening them so that they can't reproduce (or replicate) themselves very well or so that they can't replicate at all. Children given vaccines are exposed to enough of the virus or bacteria to develop immunity, but not enough to make them sick.
