You may heard concerns that vaccines can overwhelm the immune system, but that the vaccines are just a drop in the bucket compared to the number of antigens your body encounters daily? Administering multiple vaccines at once does not overwhelm the immune system as your immune system is built to handle multiple challenges at once.

This summer marked 20 years since the HPV vaccine was approved by the US Food and Drug Administration. HPV is a large family of viruses that can cause many different cancers in men and women. The HPV vaccine trains the immune system to recognize and fight the different HPV strains that cause cancer, which prevents the virus from causing infections that ever develop into cancer. In some places, the vaccine has shown incredible success at preventing cervical cancer in women.

Children's Hospital of Philadelphia has great resources on vaccines, including vaccines and aluminum. Given the quantities of aluminum we are exposed to on a daily basis, the quantity of aluminum in vaccines is tiny. Aluminum-containing vaccines have been used for decades and have been given to more than 1 billion people without problem.

Does vaccinating during pregnancy help prevent complications like preterm birth, or does it cause those complications? Vaccines during pregnancy help reduce the risk of infections that can lead to complications such as preterm birth and current evidence shows that these vaccines are not linked to an increased risk of miscarriage. If you’re weighing your options, remember this: preventing serious illness during pregnancy is one of the best ways to support both your health and your baby’s. If you have more questions, talk to a clinician or visit a local health clinic.

The American Academy of Pediatrics childhood immunization schedule is backed by decades of research to protect kids from disease and time vaccines for when their immune system is developed.

It's easy to forget how serious many vaccine-preventable diseases can be because vaccines have made them much less common. However, just because we no longer see cases of the disease, does not mean the pathogens that cause these diseases have disappeared. The pathogens are still around us in the environment. Since vaccines give the immune system a head start, it stops pathogens before they make us sick. The fact that it seems like diseases like polio or diphtheria are no longer around, is evidence that our vaccines are doing their job and protecting us.

This National Immunization Awareness Month, remember that choosing to vaccinate your child protects not only them, but their family and community as well. High vaccination rates help protect babies, older adults, and people with weakened immune systems who sometimes cannot be vaccinated and rely on community immunity to stay safe. When more people are vaccinated, diseases have fewer chances to spread.

There is no evidence that splitting the MMR (measles, mumps, rubella) vaccine into three separate vaccines would make kids safer or healthier. Importantly, these separate vaccines are not currently available in the US. Don't delay your child's protection by waiting for a product that isn't available. Measles is circulating right now, and two doses of the MMR vaccine are 97% effective at preventing measles.
