Like any medication there are pros and cons to every medication. However most of these side effects are minor and will not concern the body in most cases. These side effects include some pain and sometimes swelling at the injection site as well as mild fever. At worst some severe reactions can occur to the body such as fainting and high fevers. 1)

There are many others such as an oral vaccine which is a vaccine taken by the mouth. There are other methods such as aerosols where the actual vaccine can be inhaled. Aerosol vaccinations can be used to prevent the invasion of measles at a young age. It is a new method used for children which...
