Vaccines & Immunizations
Vaccines and Immunizations
By the time your child is 5 years old they should have had:
5 doses of Diphtheria, Pertussis, and Tetanus vaccine (DTaP)
4 doses of Polio vaccine
1 dose of Varicella vaccine
2 doses of MMR or 2 Measles, 1 Mumps, and 1 Rubella vaccine
3 doses of Hepatitis B vaccine
2 doses of Hepatitis A vaccine
1 dose of Tdap vaccine for students entering 7th - 12th grade
All kindergarten through sixth grade students must have two doses of Hepatitis A vaccine to start school. All 7th through 12th grade students must also have one dose of a Pertussis containing Tetanus vaccine, called Tdap, to enter.
Where do I go to get my child vaccinated?
You may take your child to their health care provider.
You may contact the Clackamas County Health Department Clinic for an appointment at 503.655.8471.
After my child has had their vaccines, who do I notify?
Always give your school nurse a written record of the dates the vaccinations were given to your child so that your child’s health records can be kept up-to-date at school.
ALWAYS KEEP A COPY OF YOUR CHILD’S IMMUNIZATION RECORDS IN YOUR HOME FILE. YOU WILL NEED THEM THROUGHOUT THEIR SCHOOL LIFE. PROOF OF UP-TO-DATE VACCINATIONS ARE NEEDED EVEN FOR COLLEGE AND EMPLOYMENT.
What do parents need to know about vaccines?
Immunization is a preventative measure that can protect people against serious diseases. Parents naturally have many questions about vaccines, so we've collected the most common questions and provided up-to-date answers. For more information on immunizations and vaccine safety, please visit the OHA Vaccines and Immunization Website.
How do vaccines prevent disease?
Vaccines protect people from disease by strengthening a body's immune response. A vaccine's antigens help a body make infection-fighting antibodies to combat disease invaders. Vaccines will make people immune to a disease without having to suffer through that disease.
Are these diseases really dangerous?
Yes. Many vaccine-preventable diseases, such as smallpox, are no longer around so we have forgotten how horrible they are. But up until the 1960's, parents were terrorized by polio, a devastating disease that struck healthy children and still exists in many parts of the world. With the development of vaccines, children are now protected from diseases that caused thousands of children to die. For example, since 1991 when children started receiving the Hib vaccine that prevents a serious bacterial infection, the rate of Hib-related diseases declined 99 percent, from 20,000 cases per year to approximately 35 cases.
Isn't it better for children to gain immunity naturally by getting the disease instead of the immunization?
Natural infection can come at a high price: Chicken pox or pneumococcus can lead to pneumonia; rubella can cause birth defects; Hib can cause brain damage; and children can die from any vaccine-preventable disease. A child may have a mild case or even no symptoms at all, but he or she could pass on the disease to a child who can't be immunized because of age or medical condition.
Aren't infants too young to get shots?
No. Many of the diseases that vaccines prevent occur in very young infants. Fortunately, most babies are born with sturdy immune systems that are very capable of making a protective immune response to vaccines. Vaccines don't weaken the immune system ---they boost it.
Are so many shots safe for my baby?
Several studies have determined that simultaneous vaccinations with multiple vaccines have no adverse effect on a normal child's immune system. Another advantage of multiple immunizations is that children have fewer shots, fewer office visits and less discomfort. Spreading out vaccines may leave children unnecessarily vulnerable to disease. Plus, vaccines are more efficient than ever. The original smallpox vaccine had 200 antigens in just one shot; today, there are only about 130 antigens in all of the routinely recommended immunizations combined.
Why do children get so many more shots now?
As science progresses, children and adults are protected against more and more vaccine-preventable diseases. In the 1920's, there was just one vaccine: smallpox. At that time, hundreds of thousands of children got diphtheria -- many of them died from it. Today we have vaccines for diseases that used to affect children every day.
Do vaccines cause autism?
No. Many studies that included hundreds of thousands of children across the globe have compared kids who got vaccines with kids who didn't -- there is no difference in the autism rate. Vaccines do not cause diseases, they prevent them.
Is Mercury in vaccines harmful?
There is no mercury in routine childhood vaccines. In 2001, the Food and Drug Administration (FDA) required vaccine manufacturers to stop using mercury preservatives in childhood vaccinations. Manufacturers previously used thimerosal and other types of ethyl mercury that are rapidly eliminated from the body. The only vaccine that still contains a mercury preservative is the flu vaccine that comes in a multi-dose vial. But the amount of mercury in a flu vaccine is five times less that a tuna sandwich.
Is aluminum in vaccines harmful?
There is aluminum all around us in water, food and air, it is the most common metal found in nature. Some vaccines include a small amount of aluminum to boost immunity, but aluminum is present in breast milk and baby formula. Babies quickly eliminate aluminum from their bodies with no danger to their health.
