Vaccination FAQs (cont.)

Can people receive multiple vaccinations during one visit to the doctor?

Simultaneous administration (vaccines given at the same visit but not in the same shot) of most commonly used vaccines does not decrease the response to the vaccines or increase the risk for adverse reactions. The simultaneous administration of vaccines was instituted to increase compliance with recommended immunization schedules. If people have to come back many times to get additional shots, there is an increased chance that they will not get all recommended vaccinations. In children, there are now a few combination shots that contain multiple vaccines in a single shot. Most of these are approved for use in adults, except Tdap (a three-vaccine combination) and one containing measles/mumps/rubella (MMR). There is an ongoing controversy in the public media about giving "too many" vaccines at one time to little children. Physicians, however, do not believe that children are at risk from "too many" vaccinations given at one time.

Are there any dangers to being immunized?

There is no such thing as a risk-free vaccine. However, the health risk of not being vaccinated is real and is clearly greater than that of being vaccinated. Most side effects from vaccinations are mild and limited to local reactions at the injection site and/or a mild fever. Unfortunately, there are rare serious and even fatal side effects related to vaccines. While these events are sad, not taking the vaccine could also result in death or disability.

Can people with severe egg allergies still get an annual influenza vaccination?

Since 2013, there has been an influenza vaccine specifically for people with egg allergy. Most influenza vaccines are made using eggs. Therefore, people with severe egg allergy had previously been recommended not to receive the influenza vaccine. However, the new vaccine, recombinant hemagglutinin influenza vaccine (RIV), is not made using eggs. This vaccine is safe for patients with egg allergy.
