Ensure Patients Are Up to Date With Polio Vaccination

Ensure Patients Are Up to Date With Polio Vaccination

Vaccine-derived poliovirus has been detected in environmental samples and infected one unvaccinated person in New York this year. In some Philadelphia neighborhoods, polio vaccination rates among children remain low. 

Prevent community transmission by ensuring patients are up-to-date with polio vaccines in their upcoming well or sick visit. 

According to the American Academy of Pediatrics, delaying immunizations at sick visits can lower immunization rates. Use every opportunity to vaccinate!

What is polio?

  • A potentially disabling and life-threatening disease caused by poliovirus. 
  • Usually spread through the fecal-oral route, and sometimes through the oral-oral route.
  • Most people infected with polio have no apparent symptoms. Some experience mild symptoms (e.g. sore throat, fever, nausea).
  • 1% of polio cases result in paralysis. Paralytic polio can result in death, especially among people diagnosed as adults.
  • Up to 40% of children diagnosed with polio experience new symptoms in adulthood (post-polio syndrome).

Who should get vaccinated?


  • All unvaccinated children should receive the polio vaccine (IPV).
  • CDC recommends 3 doses of IPV for primary series and 1 booster dose for children at the following ages: 
    • Dose 1: 2 months old
    • Dose 2: 4 months old
    • Dose 3: 6 through 18 months old
    • Booster: 4 through 6 years old
  • Unvaccinated or partially vaccinated children should receive IPV vaccination as soon as possible in accordance with the recommended catch-up schedule.


  • Unvaccinated or partially vaccinated adults who are at increased risk of infection (e.g. international travelers) should receive their completed series of IPV in the following intervals:
    • Dose 1: at any time
    • Dose 2: 1-2 months after Dose 1
    • Dose 3: 6-12 months after Dose 2

Digital Data Logger Download Reminder During the Holiday Season

Digital Data Logger Download Reminder During the Holiday Season

To make sure that your vaccines stay properly monitored over the busy holiday season, please be aware of the date indicator on your digital data loggers (DDLs). To prevent any gaps in temperature monitoring, please download your DDL files if the date indicator is approaching the 30 day capacity. With many offices having adjusted holiday hours or staff members taking time off, the 30 day capacity on your DDL could be reached.

To prevent this, we suggest that you download your DDL files before the holidays, especially if your office will be closed. This may mean downloading your DDL earlier than you normally would. This will ensure that they continue to record temperature readings for your storage units into the New Year.

After you download your DDL files, remember to:

1) Email both your LTD (yellow and blue) and CSV (green) files to

2) Upload your CSV files into the Clinic Tools module in PhilaVax

If you need assistance or have additional questions, please contact our Storage and Handling department at

Mpox Vaccination Update: Intradermal or Subcutaneous Regimen Permitted

Mpox Vaccination Update: Intradermal or Subcutaneous Regimen Permitted

The U.S. Department of Health and Human Services (HHS) and the CDC have updated the mpox provider agreement to allow for both an intradermal and subcutaneous route of administration to be used for mpox vaccination. There is reported vaccine hesitancy due to concern over possible hyperpigmentation or scarring following intradermal administration. This change highlights that concerns about intradermal administration should not be a barrier to vaccination.

At the height of the outbreak, the intradermal route was preferred because it increased the number of available vaccine doses, while safely providing a similar immune response against mpox. However, mpox providers now have the flexibility to offer the intradermal or subcutaneous regimen based on optimal vaccine use and acceptance, feasibility of administration, and available vaccine supply. Both subcutaneous and intradermal vaccine regimens provide a safe immune response against mpox.

For more information view the CDC’s interim clinical considerations for JYNNEOS.

Thank you for the work you are doing to promote vaccination against mpox in Philadelphia.

When checking existing vaccine inventory, be sure to apply these new expiration dates.

Get Patients On Schedule with MMR & Other Pediatric Vaccines

Get Patients On Schedule with MMR & Other Pediatric Vaccines

PDPH strongly encourages providers to ensure children are up to date with their MMR as well as other pediatric vaccines. This is especially urgent given the recent outbreak of measles in Columbus, Ohio. The outbreaks in Columbus have infected over 40 unvaccinated children, from <1 year old to 15 years of age, with cases on the rise. Nearly half of these children have been hospitalized.

Children should be vaccinated against measles at 12-15 months of age, with a booster dose at 4 years of age. Adults surrounding infants who are not yet eligible to be vaccinated are encouraged to make sure their vaccination records are up to date.

View the pediatric vaccination schedule.

Use Every Opportunity to Vaccinate

Review immunization records and recall patients who are not up to date. Use the PhilaVax Recall Report Guide to create a report of patients who are due for vaccine.

Vaccine should be administered to children with mild illnesses such as:

  • Otitis media
  • Diarrhea
  • Upper respiratory tract infections

Shelf Life Extensions on Moderna and Pfizer Products

Shelf Life Extensions on Moderna and Pfizer Products

Expiration dates of the following monovalent Moderna 10 products have been extended:

Moderna has verified the new expiration dates above and updated the Moderna Vial Expiration Checker.Additionally, Pfizer will be sending out short dated products and advises to hold on to products expiring soon in anticipation of a shelf life extension. If you have Pfizer vaccine products expiring soon set these aside and label them as “Do Not Use” until further information is received. This extension will be in reference to expiration dates only. BUD labels should still be monitored and disposed of once no longer viable.

Why the name change?

The World Health Organizations (WHO) announced this week that they are phasing out the use of the term “monkeypox.” The change was prompted by observation of racist and stigmatizing language online, in other settings, and in some communities when the outbreak expanded earlier this year.

In line with the WHO recommendation, the Philadelphia Immunization Program and CDC is phasing out use of the term “monkeypox” and will use the new term “mpox” going forward. This change from the WHO will enhance the U.S. response to mpox by using a less stigmatizing term. We appreciate your understanding as our team works to implement this change throughout the related documents, forms and webpages.
