Key takeaways

Vaccines can help train your immune system to recognize and fight certain harmful germs (viruses or bacteria) before they make you sick. They can help you defend against some serious illnesses including certain respiratory diseases.

Whether you're staying up-to-date on seasonal protection or addressing longer-term health needs, it is sometimes recommended to get more than one vaccine. This could mean getting two vaccines at the same visit or scheduling them across two appointments. Either way, staying up-to-date with vaccinations can help train your immune system response against certain respiratory diseases.

Whether you get them together or separately, staying current on your vaccinations helps protect you and those around you.

Yes, you can get more than one vaccine

The US Centers for Disease Control and Prevention (CDC) have recommended people receive more than one vaccine in a single visit where clinically recommended to help stay up to date on protection without needing multiple appointments. In most cases, multiple vaccines would be administered in different injection sites (e.g., different arms).

What matters most is completing your recommended vaccinations, especially for respiratory illnesses like flu, COVID-19, pneumococcal pneumonia, and RSV based on the recommended vaccines for your age and chronic conditions. Whether you get them together or separately, staying current on your vaccinations helps protect you.

Your immune system fights off germs every day. Vaccines only use a small part of a germ (virus or bacteria) to help your body learn how to protect itself.

Safety considerations

Getting more than one vaccine at the same visit when recommended may be considered appropriate. Side effects from vaccines, including vaccines to help prevent respiratory infections, can occur. These can be signs your immune system is responding.

While common side effects can be mild and last a few days, like pain at the injection site or fatigue, serious side effects can occur and may include serious allergic reactions, fainting after vaccination, as well as other risks. For more information, read What to know about vaccine side effects.

You can report any unexpected side effects to the Vaccine Adverse Event Reporting System (VAERS) at vaers.hhs.gov.

Benefits of getting more than one vaccine

Getting vaccinated against more than one disease in a single visit, when recommended, means fewer trips to your healthcare provider or pharmacy. Fewer appointments means less time off work, fewer transportation hassles, and fewer missed opportunities to stay up to date with your respiratory vaccine schedule.
