” A perfect universal influenza vaccine might be taken less frequently than when a year and safeguard against multiple strains of influenza infection. With each new universal influenza vaccine prospect and medical trial, we take another action more detailed to that goal,” said Acting NIAID Director Hugh Auchincloss, M.D
. About the Vaccine Candidate: FluMos-v2.
The vaccine candidate under investigation, FluMos-v2, was developed by scientists at NIAIDs Vaccine Research Center (VRC). It is an adjustment of an earlier universal flu vaccine candidate, FluMos-v1, which began first-in-human testing in 2021 and is still undergoing trials. FluMos-v2 is developed to induce antibodies versus several influenza infection pressures by showing part of the influenza infection hemagglutinin (HA) protein in duplicating patterns on self-assembling nanoparticle scaffolds. Exposure to these safe fragments of infection proteins prepares the body immune system to acknowledge and battle the real virus. When checked in animals, the speculative vaccine resulted in robust antibody actions.
While the FluMos-v1 vaccine candidate shows HA from four stress of influenza infection, FluMos-v2 shows HA from six: 4 influenza A viruses and 2 influenza B viruses. The scientists expect that this will further expand vaccine receivers resistance, offering protection against a wider range of influenza infections.
Trial Details and Follow-up.
The new clinical trial is anticipated to register 24 healthy volunteers, aged 18-50 years, who will get two intramuscular injections of the FluMos-v2 vaccine prospect. These injections will be offered 16 weeks apart. In the beginning, participants will be enrolled in the lower dose group (60 mcg per vaccination). If no safety issues are recognized after at least three participants have actually received this dosage, enrollment will start in the higher dosage (180 mcg per vaccination) group. The study team prepares to enroll 12 participants in each dosage group.
For 40 weeks after their very first vaccination, individuals will get routine follow-up telephone call and evaluations to track their actions to the speculative vaccine. Blood samples will be taken throughout research study visits to determine any immune responses to the vaccine candidate.

A Phase 1 trial for the investigational universal influenza vaccine candidate, FluMos-v2, has actually started at the National Institutes of Healths Clinical Center in Bethesda. Currently, readily available seasonal influenza (or “flu”) vaccines are efficient at avoiding specific strains of influenza. Many seasonal flu vaccines are developed to train the immune system to safeguard versus three or four different common stress of flu, but a “universal” influenza vaccine might one day offer security against many more.

Vaccine Candidate FluMos-v2 Targets Six Flu Strains.
A Phase 1 trial for the investigational universal influenza vaccine prospect, FluMos-v2, has started at the National Institutes of Healths Clinical Center in Bethesda. Sponsored by the National Institute of Allergy and Infectious Diseases, the trial will examine the vaccines security and immune response potential. FluMos-v2, an advancement of FluMos-v1, intends to use more comprehensive resistance versus six pressures of influenza infections.
Enrollment in a Phase 1 trial of a brand-new investigational universal influenza vaccine candidate has begun at the National Institutes of Healths Clinical Center in Bethesda, Maryland. The trial is sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), and will assess the investigational vaccine for safety and its ability to elicit an immune action.
Present Influenza Vaccines.
Currently, offered seasonal influenza (or “flu”) vaccines are reliable at preventing specific stress of influenza. Each year, the vaccines are re-evaluated and altered to finest match the stress of flu predicted to be the most dominant in the upcoming influenza season. Many seasonal flu vaccines are designed to train the immune system to prevent 3 or 4 various typical stress of flu, but a “universal” influenza vaccine might someday offer security against a lot more.
