First I'm afraid to vaccinate, because of many news around the world have side effects after their inject the vaccine. But many doctors said that's is normal, many vaccinated have some mild side effect then their gone, they said if you have other sickness its better to tell them before you vaccinate.
Yeah it is scary at first since the effectivity is not yet perfected but look at us right now, Polio, diptheria, Tetanus, Hepatitis A, Hepatitis B, Rubella, Hib, Measles, and Rotavirus would still be a problem and a lot of people are dying to this if we didn't have vaccines made against it. Don't be scared to get vaccinated, you are probably safe.
