A: There are some vaccines which should not be given together and there are recommended minimum time periods for intervals between vaccinations. For each of the vaccines, you can consult the CDC's recommended schedules and the manufacturer product inserts to learn about official recommendations for time periods between vaccinations.
Some people choose to wait for two to four months or more between vaccinations. Using all available information and/or working with a trusted health care professional, you may want to develop a tailored vaccination schedule that you are comfortable using. To learn more about vaccines and diseases and their associated risks you can also visit NVIC's referenced vaccine and disease web pages.
