Vaccinations protect you and others

COVID-19 vaccines are safe and effective:

  • The vaccines help prevent transmission, severe symptoms, hospitalization, long COVID, and death. 
  • Breakthrough cases in fully vaccinated people are uncommon and lead to less severe illness than among unvaccinated people. 
  • People who are unvaccinated are 5 times more likely to catch COVID-19 than those who are vaccinated, more than 10 times more likely to be hospitalized from COVID-19 than those who are vaccinated, and more than 10 times more likely to die from it.

As more people are vaccinated...

  • stress on the healthcare system will decrease. Because of the current surge in COVID-19 cases in people who aren't vaccinated, hospital ICU beds may be scarce, reducing the availability of care for other urgent health problems like heart attacks, strokes, and appendicitis.
  • COVID-19 will have less opportunity to mutate into new versions.

Get vaccinated now

Vaccines are widely available and anyone age 12 and older may walk in or schedule an appointment. Ages 12–17 will receive the Pfizer vaccine and must be accompanied by a parent or guardian. U.S. citizenship is not required.

COVID-19 vaccine booster - Friday, November 19, 2021

The U.S. Food and Drug Administration expanded recommendations for booster shots to include all adults ages 18 years and older who received a Pfizer-BioNTech or Moderna vaccine at least six months after their second dose.

If you believe you qualify for a booster, contact your healthcare provider for more information.

COVID-19 Vaccine for Children Aged 5-11

On Tuesday, November 2, the CDC endorsed the FDA’s authorization for emergency use of the Pfizer-BioNTech COVID-19 vaccine for children ages 5-11 years old. The Pfizer-BioNTech vaccine is safe and effective for this age group and was found to be 90.7% effective in preventing COVID-19. Children in this age group will receive two doses, given at least three weeks apart. The dose they will receive is one-third of the dose (10 micrograms) that is given to those ages 12 and up (30 micrograms). Additionally, smaller needles will be used.  

Children may experience some side effects. Side effects are normal and a sign that the body is building protection.  If you don’t experience side effects, that does not mean that the vaccine is not working. Everyone responds differently. If side effects do occur, they should go away within a few days. More information can be found on the CDC page COVID-19 Vaccines for Children and Teens.  

It may take time for some locations to offer vaccines to this new age group and the CDC anticipates more availability in the coming weeks. It is highly recommended to schedule your child’s COVID-19 vaccine appointment ahead of time rather than walking into a location administering vaccinations to children. There is a high demand for this age group. To ensure your child gets vaccinated at a time that is convenient for you, It is recommended that you schedule an appointment at your preferred location.  

Take the following steps to get your child vaccinated: 

  • Contact your child’s pediatrician or your family doctor. 
  • Check with your local pharmacy. 
  • Look for communication from your child’s school about upcoming vaccination clinics. 
  • Register on AllVax so that you will be notified when you can schedule an appointment through the Lake County Health Department. Limited appointments will be available at our Grand Avenue Health Center and Midlakes Health Center. 
  • Visit to find a provider near you that may have pediatric vaccines available.  

Read the full statements from the FDA and CDC for more information about the Emergency Use Authorization (EUA) for the Pfizer-BioNTech vaccine for children ages 5-11.
