Nipah virus (NiV) is transmitted from animals to humans, from humans to humans, and through contaminated food. Infected people may have a cough and trouble breathing. Some people may develop serious symptoms, such as brain inflammation, that can lead to death. There are no drugs or vaccines to treat or prevent NiV infection.


To test the safety of an experimental vaccine (mRNA-1215) for NiV. Researchers will also evaluate how participants bodies respond to the vaccine.


Healthy, nonpregnant adults aged 18 to 60 years.


Participants will visit the NIH clinic 13 to 15 times over 14 to 16 months.

Participants will get 2 doses of the experimental vaccine during this study at either 1 month or 4 months apart. The vaccine will be given as a shot into the muscle of the upper arm. Participants will stay in the clinic at least 30 minutes after each vaccination.

Participants will be given a diary card and a thermometer. They will record their temperature and any other symptoms for 7 days after each vaccination.

During each follow-up visit, 3 to 14 tubes of blood will be drawn for research.

Participants may undergo an optional procedure called apheresis. A needle will be placed into a vein in each arm. Blood will be removed through one needle. The blood will pass through a machine that separates some of the blood cells. The rest of the blood will return to the body through the other needle.

The study vaccine cannot cause NiV infection.

A subject will be excluded if one or more of the following conditions apply:

1. Breast-feeding or planning to become pregnant during the study.

2. More than 10 days of systemic immunosuppressive medications or cytotoxic medications within the 4 weeks prior to enrollment or any within the 14 days prior to enrollment.

3. Blood products within 16 weeks prior to enrollment.

4. Any vaccine, including COVID-19 vaccines, received within 4 weeks prior to enrollment.

5. Investigational research agents within 4 weeks prior to enrollment or planning to receive investigational products while on the study

6. Current allergy treatment with allergen immunotherapy with antigen injections, unless on maintenance schedule.

7. Current anti-TB prophylaxis or therapy.

8. Known immediate hypersensitivity to any component of the study product, including polyethylene glycol (PEG).
