Vaccines save lives. That’s the message Dr. Priya Sampathkumar, an infectious diseases specialist at Mayo Clinic, wants the public to know.

With the ongoing COVID-19 pandemic, Sampathkumar says it is doubly important that everyone get a flu vaccine. While getting a flu vaccine won’t protect against COVID-19, flu vaccines have been shown to reduce the risk of flu illness, hospitalization and death.

In this Q&A, Sampathkumar answers questions about vaccines, why immunizations are important and what parents and caregivers should do if they have concerns:

What are the current flu vaccine recommendations?

The current recommendation is that everyone over the age of 6 months should get the flu vaccine. This year it is doubly important that everyone get the flu vaccine because if people have fever and respiratory symptoms in the fall, the first concern is going to be COVID-19. The symptoms of the two diseases are hard to tell apart. If you get the flu vaccine, you are less likely to get the flu and less likely to be thought of as a possible COVID-19 case.

Why are vaccines so important to public health?

Vaccines have been hailed as the biggest public health achievement of the 20th century. … In the U.S., for instance, we don’t see polio, we don’t see tetanus, we don’t see diphtheria cases. And many other diseases have been reduced to low levels. This is all due to vaccines.

It’s estimated that in the world, vaccines prevent about 285 deaths an hour. Vaccines are effective, they have a good safety record and they do a lot of good. They save lives.

How are vaccines tested for safety?

Typically, it takes six to eight years to bring a vaccine to market. The first step in developing a vaccine is to do phase 1 trials, where the vaccine is tested in laboratory settings to make sure the vaccine works against the disease it is intended to protect against. The next step is phase 2 trials. This is where the vaccine is tested on a small group of volunteers — usually 10 to 20 people — to see what the optimal dose is after the vaccine has been shown to be safe for humans. The third step is phase 3 trials. Here we test many more people and look at how effective the vaccine is in real-life situations and how safe the vaccine is for humans. And then there are multiple reviews of the vaccine by regulatory agencies. … Vaccines are rigorously vetted, and I would say they are much safer than many drugs on the market.

What is your recommendation to parents who have questions or concerns about vaccinating their child?

Vaccines are the best thing you can do to protect your child from illness. If you have questions, there are so many sources of credible information out there, including the American Academy of Pediatrics and the Centers for Disease Control and Prevention, but nothing beats talking with your child’s health care provider. He or she will guide you and help you make decisions.

What are good sources of information about vaccine safety?

There is a lot of unreliable information out there, so it is easy to get lost in social media posts that highlight misinformation about vaccines. If you have questions, talk with your health care provider. That’s probably the most reliable source of information.
