What is a vaccine?
Vaccines contain weakened versions of a virus or versions that look like a virus (called antigens). This means the antigens cannot produce the signs or symptoms of the disease, but they do stimulate the immune system to create antibodies. These antibodies help protect you if you are exposed to the virus in the future.
Vaccines not only help keep your child healthy, they help all children by stamping out serious childhood diseases.
Are vaccines safe?
Vaccines are generally safe. The protection provided by vaccines far outweighs the very small risk of serious problems. Vaccines have made many serious childhood diseases rare today. Talk to your family doctor if you have any questions.
Do vaccines have side effects?
Some vaccines may cause mild, temporary side effects, such as fever, soreness, or a lump under the skin where the shot was given. Your family doctor will talk to you about possible side effects with certain vaccines.
When should my child be vaccinated?
Recommendations about when to have your child vaccinated changes from time to time. You can get a copy of the most current child and adolescent vaccination schedules from an organization, such as the American Academy of Family Physicians, the Centers for Disease Control and Prevention (CDC), or you can ask your family doctor. Your child usually receives their first vaccine soon after they are born.
Are there any reasons my child should not be vaccinated?
In special situations, children shouldn’t be vaccinated. For example, some vaccines shouldn’t be given to children who have certain types of cancer or certain diseases, or who are taking drugs that lower the body’s ability to resist infection.
If your child has had a serious reaction to the first shot in a series of shots, your family doctor will probably talk with you about the pros and cons of giving him or her the rest of the shots in the series.
Talk to your doctor if you have any questions about whether your child should receive a vaccine.
What is the flu vaccine?
The flu vaccine (also called the influenza vaccine) is available by shot or by nasal spray. However, the CDC recommend the nasal-spray vaccine should not be used for the 2016-2017 flu season. Data from the CDC and other groups showed poor or relatively lower effectiveness of the nasal spray vaccine during previous flu seasons.
The flu shot contains a version of a virus that looks like a virus. The nasal-spray vaccine contains live, but weakened viruses. You cannot get the flu from the flu shot or the nasal-spray vaccine.
The flu vaccine is given at the beginning of the flu season, usually in October or November. The flu shot is safe for children 6 months of age and older. The nasal spray vaccine is safe for children 2 years of age and older. Because flu viruses change from year to year, it is very important for your child to get the vaccine each year so that he or she will be protected. Children are more likely to have complications from the flu.
What is the DTaP vaccine?
The DTaP vaccine is 3 vaccines in 1 shot. It protects against diphtheria, tetanus and pertussis. It’s given as a series of 5 shots, the first when your child is 2 months old and the last when they are 4- to 6 years old.
Diphtheria is a disease that attacks the throat and heart. It can lead to heart failure and death. Tetanus is also called “lockjaw.” It can lead to severe muscle spasms and death. Pertussis (also called “whooping cough”) causes severe coughing that makes it hard to breathe, eat, and drink. It can lead to pneumonia, convulsions, brain damage, and death.
Having your child immunized when he or she is young (which means making sure he or she gets all of the DTaP shots) protects your child against these diseases for about 10 years. After this time, your child will need booster shots.
What is the Td vaccine?
The Tdap vaccine is used as a booster to the DTaP vaccine. It helps prevent tetanus, diphtheria, and pertussis. It’s given when your child is 11 years old or older.
What is the rotavirus vaccine?
The rotavirus vaccine protects against rotavirus. Your child will receive either a two-dose, at 2 and 4 months of age, or a three-dose series, at 2, 4, and 6 months of age, depending on what your doctor recommends. All doses should be given by no later than age 8 months of age.
Rotavirus is a virus that causes diarrhea, mostly in babies and young children. The diarrhea can be severe and cause dehydration. Rotavirus can also cause vomiting and fever in babies.
After rotavirus vaccination, call your family doctor if your child has stomach pain with severe crying (which may be brief), vomiting, blood in the stool, or is acting weak or very irritable. This is especially important within the first seven days after rotavirus vaccination. Contact your doctor if your child has any of these signs, even if it has been several weeks since the last dose of vaccine.
What is the IPV vaccine?
The IPV (inactivated poliovirus) vaccine helps prevent polio. It’s given four times as a shot, from age 2 months to 6 years.
Polio can cause muscle pain and paralysis of one or both legs or arms. It may also paralyze the muscles used to breathe and swallow. It can lead to death.
What is the MMR vaccine?
The MMR vaccine protects against the measles, mumps, and rubella (MMR). It’s given as 2 shots when your child is 1 year old and again when they are 4- to 6 years old.
The measles cause fever, rash, cough, runny nose, and watery eyes. It can also cause ear infections and pneumonia. Measles can also lead to more serious problems, such as brain swelling and even death.
The mumps cause fever, headache, and painful swelling of one or both of the major saliva glands. Mumps can lead to meningitis (infection of the coverings of the brain and spinal cord) and, very rarely, to brain swelling. Rarely, it can cause the testicles of boys or men to swell, which can make them unable to have children.
Rubella is also called the German measles. It causes a slight fever, a rash and swelling of the glands in the neck. Rubella can also cause brain swelling or a problem with bleeding.
If a pregnant woman catches rubella, it can cause her to lose her baby or have a baby who is blind or deaf, or has trouble learning.
Some people have suggested that the MMR vaccine causes autism. However, research has shown that there is no link between autism and childhood vaccinations.
What is the Hib vaccine?
The Hib vaccine helps prevent Haemophilus influenzatype b, a leading cause of serious illness in children. It can lead to meningitis, pneumonia and a severe throat infection. The Hib vaccine is given as a series of 3 or 4 shots, from age 2 months to 15 months.
What is the varicella vaccine?
The varicella vaccine helps prevent chickenpox. It is given to children once after they are 12 months old and again at 4- to 6 years old, or to older children if they have never had chickenpox or been vaccinated.
What is the HBV vaccine?
The HBV vaccine helps prevent hepatitis B virus (HBV) infection, an infection of the liver that can lead to liver cancer and death. The vaccine is given as a series of 3 shots, with the first shot given soon after birth.
What is the pneumococcal conjugate vaccine?
The pneumococcal conjugate vaccine (PCV) protects against a type of bacteria that is a common cause of ear infections. This type of bacteria can also cause more serious illnesses, such as meningitis and bacteremia (infection in the blood stream). Infants and toddlers are given 4 doses of the vaccine at 2, 4, 6, and 12 months of age. The vaccine may also be used in older children who are at risk for pneumococcal infection.
What is the meningococcal conjugate vaccine?
The meningococcal conjugate vaccine (MCV4) protects against four strains (“types”) of bacterial meningitis caused by the bacteria N. meningitidis. Bacterial meningitis is an infection of the fluid around the brain and spinal cord. It is a serious illness that can cause high fever, headache, stiff neck, and confusion. It can also cause more serious complications, such as brain damage, hearing loss, or blindness.
Children should get the MCV4 vaccine at 11 to 12 years of age. Children older than 12 years of age who have not received the vaccine should receive it before starting high school.
What is the HPV vaccine?
The HPV vaccine helps prevent human pappilomavirus infection, which can caused cervical cancer as well as genital warts. It is given as a 3- shot series.
