New & Updated

·       CDC Recommends Moderna Booster at 5 Months: On January 4thCDC made this recommendation for recipients of a Pfizer-BioNTech primary series. After FDA action on January 7th,  we’re extending this recommendation to recipients of a Moderna primary series. This means that people who initially received an mRNA vaccine series—–two doses of Moderna or Pfizer-BioNTech —can now receive an mRNA booster shot 5 months after completing their initial series.   

·       Guidance for COVID-19 Prevention in K-12 Schools was recently updated to reflect new recommendations for isolation for people with COVID-19 and recommendations for people who have come into close contact with a person with COVID-19.

·       CDC Expands Booster Shot Eligibility and Strengthens Recommendations for 12-17 Year Olds: CDC now recommends that adolescents age 12 to 17 years old should receive a booster shot 5 months after their initial Pfizer-BioNTech vaccination series.

·       CDC Recommends Pfizer Booster at 5 Months, Additional Primary Dose for Certain Immunocompromised Children: On January 4th, CDC updated its recommendation for when many people can receive a booster shot, shortening the interval from 6 months to 5 months for people who received the Pfizer-BioNTech COVID-19 Vaccine.

·       Stay Up to Date with Your Vaccines: To align with standard language CDC uses about other vaccinations, CDC is now using the phrase “up to date” when talking about COVID-19 vaccination. CDC recommends that individuals stay “up to date” by receiving any additional doses they are eligible for, according to CDC’s recommendations, to ensure they have optimal protection against COVID-19. The technical definition of “fully vaccinated”—two doses of an mRNA vaccine or one dose of the J&J vaccine—has not changed.

Vaccine Information

Covid-19 vaccines are safe, effective, and the cost is covered by insurance or through federal vaccine programs. People who are fully vaccinated can safely resume many activities.

Types of available vaccines:

  Pfizer-BioNTech^ Moderna
Minimum Age 6 months of age 6 months of age
Series 3 doses given over 4 months for patients 6 months to 4 years of age. 2 doses given over 2 months for patients 5 thru 18 years of age. 2 doses given 4 - 8 weeks apart
Booster* >2 months after second dose in series for persons above 5 years of age. Bivalent mRNA for booster dose. >2 months after 2nd dose in series for qualified persons above 6 years of age. Bivalent mRNA for booster dose.
When fully vaccinated 2 weeks after booster dose OR completed primary series within past 5 months 2 weeks after booster dose OR completed primary series within past 6 months
Partially vaccinated Has received only one or two doses of primary series  or completed the primary series of Pfizer vaccine over 5 months ago and is not boosted Has received only one dose or completed the primary series of Moderna vaccine over 6 months ago and is not boosted

^ Children 6 mo to 4 years of age receiving the Pfizer BioNTech vaccine will require 3 doses to complete the primary series. The third dose should be given 8 weeks after 2nd dose. 
*Any of the three COVID-19 vaccines can be used for the booster dose.

* People under 5 are not eligible for a booster dose and therefore may become partially vaccinated and yet remain ineligible for a booster.

*People with weakened immune systems, including people who take immunosuppressive medications, may not be protected even if fully vaccinated

Mask Information

We recommend the use of a well-fitted mask for individuals 2 years of age and older, especially when in public indoor settings, regardless of vaccination status. Masks work by containing some of your airborne germs and protecting you from breathing in some of the germs from people around you. This is important because Covid19 can be spread through airborne particles.

There are different types of masks – the type you choose may depend on factors such as cost and availability. The fit of the mask is important. No matter what type you choose the mask should:

  • Cover your mouth and nose
  • Fit snuggly without gaps around the sides of the face and nose

Avoid masks that:

  • Have a valve or vent or other openings
  • Are a single layer fabric or thin fabric that doesn’t block light
  • Are wet or dirty

Mask myth busters:

Ways to make mask-wearing easier

  • Consider the use of a mask bracket or KF94 mask to help the mask stay off your face
  • Start getting used to the mask slowly by holding it in your hand, touching it to the face, or wearing it around one ear. Gradually work your way up to wearing the mask at home for short periods of time and during favorite activities.  Also, consider putting the mask on favorite toys, reading books about mask-wearing, positive reinforcement (favorite treats) for mask use, and modeling mask-wearing. 
  • Consider hypnotherapy or counseling to help with mask anxiety

A school-aged child qualifies for a mask exemption ONLY if they are unable to remove a cloth face mask independently. Adaptions to the learning environment should be explored for children in need of communication assistive devices and those with other disabilities that make them unable to tolerate wearing a mask. 

To improve mask fit:

  • Adjust ear straps
  • Use the nose wire to tighten the fit.
  • Tie a knot in the straps close to the filter material to snug it around the face
  • Use a Badger Seal or Fix the Mask 

Teaching points

  • Masks are germ catchers – wash your hands before and after you handle your mask
  • Use the ear straps to put a mask on and take it off
  • Cloth masks should be washed daily in soap and water. 
  • Wearing a disposable mask underneath a cloth mask will provide extra protection
