What You Need to Know: On December 18, 2020, the Food and Drug Administration issued the second emergency use authorization (“EUA”) for a vaccine for the prevention of COVID-19 in individuals 18 years of age and older. Under the EUA, the Moderna COVID-19 Vaccine can be distributed in the U.S. and shipment has begun and immunizations will begin this week.
FDA’s analysis of the efficacy data from 28,207 participants 18 years of age and older without evidence of SARS-CoV-2 infection prior to dose one confirms the vaccine was 94.1% effective in preventing COVID-19 occurring at least 14 days after the second dose. The most common adverse reactions reported were pain at the injection site, erythema (like reddening of the skin), swelling, enlarged lymph nodes and a higher rate of severe reactions after the second dose.
Moderna has said it plans to continue to monitor all clinical trial participants for two years. The manufacture of the authorized Moderna COVID 19 Vaccine is limited to those facilities identified and agreed upon in the ModernaTX, Inc. request for authorization.
In order to mitigate the risks of using this unapproved product under EUA and to optimize the potential benefit of the Moderna COVID-19 Vaccine, the following items are required.
The Moderna COVID 19 Vaccine must be accompanied with product specific information to be made available to vaccination providers and recipients:
Use of unapproved Moderna COVID-19 Vaccine for active immunization to prevent COVID-19 under the EUA is limited to the following (all requirements must be met):
The vaccination provider is responsible for responding to FDA requests for information about vaccine administration errors, adverse events, cases of MIS in adults and cases of COVID-19 that result in hospitalization or death following administration of the Moderna COVID-19 Vaccine to recipients.
The Moderna COVID-19 Vaccine vial label and carton labels are required to be clearly marked for “Emergency Use Authorization.”
The Moderna COVID-19 Vaccine multiple-dose vials must be stored frozen between -25º to -15ºC (-13º to 5ºF) and should be stored in the original carton to protect from light. Unlike the Pfizer vaccine, the Moderna COVID-19 Vaccine should not be stored on dry ice or below -40ºC (-40ºF).
Vials can be stored refrigerated between 2° to 8°C (36° to 46°F) for up to 30 days prior to first use. Unpunctured vials may be stored between 8° to 25°C (46° to 77°F) for up to 12 hours. Do not refreeze once thawed.
The Moderna COVID-19 Vaccine is administered intramuscularly as a series of two (0.5 mL each) one month apart.
There is no data available on the interchangeability of the Moderna COVID-19 Vaccine with other COVID-19 vaccines to complete the vaccination series. Individuals who have received one dose of the Moderna COVID-19 Vaccine should receive a second dose of the Moderna COVID19 Vaccine to complete the vaccination series.
There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to Moderna COVID-19 Vaccine during pregnancy. Women who are vaccinated with Moderna COVID-19 Vaccine during pregnancy are encouraged to enroll in the registry by calling 1-866- MODERNA (1-866-663-3762).
In summary, once again, it is clearly evident that FDA conducted a thorough review and evaluation of the information and data submitted by Moderna regarding the COVID 19 Vaccine. It is also clear that there are a number of requirements that must be met to ensure that the vaccine is properly controlled, distributed, stored and administered to the public. Most importantly, there are extensive post marketing pharmacovigilance requirements necessary to monitor the safety profile of the product. We will be reporting on other vaccines as they may be available in the future under EUA.
