It is safe to combine several vaccines for different diseases at the same time. Numerous studies evaluating the effects of combinations of vaccines and of giving children several vaccines at once show this approach is as effective as giving children individual vaccines with no greater risk for side effects.

Giving a child two or more vaccines during one healthcare visit not only provides maximum protection but reduces required office visits, saves time and money and minimizes trauma (from the shots) to the child. There are also combination vaccines, in which multiple vaccines are delivered in one shot.
It is completely safe for children to get several vaccinations at one time. In fact, as many as five or six vaccines are given at one time in the recommended vaccination schedule. Our body’s immune system is capable of responding to hundreds of different diseases or antigens at one time and is well equipped to deal with the vaccines. Giving vaccines at one time also limits the number of days that children may experience common, mild vaccine side effects such as muscle aches and fevers.

Both the Advisory Committee on Immunization Practices and the American Academy of Pediatrics conducted studies to examine the effects of various combinations of vaccines given simultaneously. The vaccines were as effective in combination as they were individually. Also, the combinations did not produce a greater number of adverse side effects. As a result, both groups recommend simultaneous administration of all routine childhood vaccines. In fact, research is trying to find ways to combine more antigens (substances that evoke an immune response) in a single vaccine injection (e.g., the measles-mumps-rubella vaccine with the chickenpox vaccine).

Vaccines & Immunizations

Vaccines are commonly given to children in the form of a shot to help prevent serious diseases like measles and mumps. Vaccines are developed using either dead strains of a disease, weakened strains, or strains of a different dise...

ase. As adults, we receive flu vaccines or may need a booster of childhood vaccines to retain immunity. Travelers may receive vaccines either as a condition of entry to a country, or on recommendation of health officials. Generally there is little or no reaction to a vaccine, but in some cases the vaccine may cause an allergic reaction or a temporary, mild illness. Some vaccines are not safe for pregnant women, so it’s important to check with a healthcare professional.
