Equally use dwell viruses but only JYNNEOS is non-replicating, creating it the safer solution, explained McQuiston.
Individuals who are immunocompromised or have distinct pores and skin ailments, like eczema, are at better threat, additional John Brooks, a clinical epidemiologist.
Transmission of monkeypox happens by means of shut, sustained pores and skin-to-pores and skin make contact with with somebody who has an lively rash, or by means of respiratory droplets in somebody who has lesions in their mouth and is all around yet another particular person for an prolonged period of time of time.
