This makes it easier to distribute and administer in various healthcare settings, including doctor’s offices, clinics, and pharmacies. Once thawed, the vaccine can be kept in a refrigerator between 2°C and 8°C (36°F and 46°F) for up to 30 days. These storage conditions make it more accessible for communities with limited access to specialized cold storage facilities.
It is important to note that the vaccine should not be frozen again once it has been thawed for use. Thawed vaccine vials should be stored in a refrigerator and used within the specified time frame.
Vaccine Administration
The Moderna vaccine is administered as a series of two doses, given 28 days apart. It is given as an intramuscular injection, typically in the upper arm. The vaccine is recommended for individuals aged 18 and older.
After receiving both doses of the vaccine, it takes time for the immune system to develop protection against the virus. Full protection is generally achieved about two weeks after the second dose.
It is important to follow the guidance of healthcare professionals and local authorities regarding vaccine eligibility, administration, and any potential side effects.
