Hospitalizations have also increased. As the holiday season continues with families gathering and traveling, DPH urges you to stay vigilant.

Additional Information from the Press Release regarding Covid-19 Data and Vaccines

DOVER, DE (Dec. 15, 2022) – The Delaware Division of Public Health (DPH) is providing several key updates related to COVID-19 data and vaccines.  According to the most recent data on the state’s My Healthy Community data dashboard, the statewide 7-day average of new positive COVID-19  cases has increased slightly following Thanksgiving and other gatherings over the past month. Hospitalizations have also increased. As holiday travel increases and families gather in coming weeks, residents are urged to remain vigilant and protected against the COVID-19 virus. Consider masking up while shopping, testing before and after gatherings, and being prepared by getting vaccinated with the updated COVID booster. As of Dec. 15, the Centers for Disease Control and Prevention (CDC) reports COVID-19 community levels in Kent and Sussex counties as medium. New Castle County is low. 

Vaccine Effectiveness Study – This week marks two years since the first patient in the United States received a COVID-19 vaccine. As the virus evolved and more variants emerged, the U.S. adjusted the program with the recommendation of additional doses and variant-specific boosters.  A recently published Commonwealth Fund study estimates that from December 2020 through November 2022, the U.S. COVID-19 vaccination program prevented more than 3.2 million additional deaths and 18.5 million additional hospitalizations. In addition, the modeling indicates that there would have been nearly 120 million more COVID-19 infections over that time period and the vaccination program saved over $1.15 trillion in medical costs that would have been incurred otherwise in the United States alone. Given increases in cases amid the co-circulation of three respiratory viruses, getting vaccinated against COVID-19 is more important than ever.

Bivalent Boosters for Infants/Toddlers – On Dec. 9, the Food and Drug Administration (FDA) granted Emergency Use Authorization to Moderna to expand use of the bivalent booster to ages 6 months – 5 years. In addition, Pfizer’s bivalent booster received Emergency Use Authorization for use as the third dose in the primary series for 6 months – 4 years of age, but not for use as a bivalent booster. Those ages 5 and older are eligible for a Pfizer bivalent booster, and those ages 6 and older are eligible for a Moderna bivalent booster, under previous authorizations. Specifically: 

  • Children 6 months through 5 years of age who received the original (monovalent) Moderna COVID-19 Vaccine are now eligible to receive a single booster of the updated (bivalent) Moderna COVID-19 Vaccine two months after completing a primary series with the Moderna COVID-19 Vaccine. 
  • Children 6 months through 4 years of age who have not yet begun their three-dose primary series of the Pfizer-BioNTech COVID-19 Vaccine or have not yet received the third dose of their primary series, will now receive the updated (bivalent) Pfizer-BioNTech COVID-19 vaccine as the third dose in their primary series. 
  • Children 6 months through 4 years of age who have already completed their three-dose primary series with the original (monovalent) Pfizer-BioNTech COVID-19 Vaccine will not be eligible for a booster dose of an updated bivalent vaccine at this time. Children in this age group who already completed their primary series would still be expected to have protection against the most serious outcomes from the currently circulating omicron variant. 

DPH expects supply of these bivalent doses for infants and toddlers to arrive in Delaware this week.  As soon as supply is received, providers may begin administration. Full details and information about where to obtain these vaccines are available at and

Transition to weekly reporting of COVID-19 data on My Healthy Community – Starting Thursday, Dec. 15, 2022, COVID-19 data reporting on the Division of Public Health’s My Healthy Community (MHC) data portal will transition from daily to weekly updates. This is consistent with the CDC’s reporting structure, which moved to providing weekly data updates in October. Going forward, the COVID-19 dashboard will be updated every Wednesday with a reporting time frame from Wednesday of the prior week to Tuesday of the current week. In the event of a significant surge in cases, while DPH will not revert back to daily data reporting on the dashboard, the agency will work to make more real-time data available. The next update on MHC will be posted Wednesday, Dec. 21.
