The number of vaccines you can get at one time will depend on your individual health needs and those of the vaccine. Some vaccines require multiple doses or a booster dose, and some can be given together in the same visit.
Generally, the Centers for Disease Control and Prevention (CDC) recommends that adults receive two or more vaccines during a single doctor’s visit as long as they are not the same vaccine and are approved to be given together. A healthcare provider should be consulted to determine the number and type of vaccines that are right for an individual.
In some cases, it may be possible to get three or more vaccines at once. For example, the CDC recommends that adults receive a tetanus, diphtheria, and pertussis (Tdap) vaccine as well as a measles, mumps, and rubella (MMR) vaccine at the same time. In addition, the CDC also recommends that adults receive a meningococcal vaccine, which can be given in combination with the Tdap and MMR vaccines.
In general, the number of vaccines that can be given at once should be determined by a healthcare provider. The healthcare provider will assess the individual’s immunization history and determine which vaccines are necessary and can be given together.
