Vaccination
Other effects
 |
Vaccination began over a century ago, and in many countries it has been almost obligatory for 60 years. Some vaccines have side-effects. Vaccines are safe, but sometimes they can be a bit painful at the jab site, or cause a mild fever or an allergic reaction. However, these side-effects are always better than having the actual disease. Some people think that vaccines are not necessary. They’re wrong. It’s very difficult for someone never to come into contact with any disease and, if they haven’t been vaccinated, they can get infected. |
