Successful respiratory immunization with dry powder live-attenuated measles virus vaccine in rhesus macaques.

چکیده
Measles remains an important cause of childhood mortality worldwide. Sustained high vaccination coverage is the key to preventing measles deaths. Because measles vaccine is delivered by injection, hurdles to high coverage include the need for trained medical personnel and a cold chain, waste of vaccine in multidose vials and risks associated with needle use and disposal. Respiratory vaccine delivery could lower these barriers and facilitate sustained high coverage. We developed a novel single unit dose, dry powder live-attenuated measles vaccine (MVDP) for respiratory delivery without reconstitution. We tested the immunogenicity and protective efficacy in rhesus macaques of one dose of MVDP delivered either with a mask or directly intranasal with two dry powder inhalers, PuffHaler and BD Solovent. MVDP induced robust measles virus (MeV)-specific humoral and T-cell responses, without adverse effects, which completely protected the macaques from infection with wild-type MeV more than one year later. Respiratory delivery of MVDP was safe and effective and could aid in measles control.

Evaluation of Measles Vaccine Virus as a Vector to Deliver Respiratory Syncytial Virus Fusion Protein or Epstein-Barr Virus Glycoprotein gp350
Live attenuated recombinant measles vaccine virus (MV) Edmonston-Zagreb (EZ) strain was evaluated as a viral vector to express the ectodomains of fusion protein of respiratory syncytial virus (RSV F) or glycoprotein 350 of Epstein-Barr virus (EBV gp350) as candidate vaccines for prophylaxis of RSV and EBV. The glycoprotein gene was inserted at the 1(st) or the 3(rd) position of the measles viru...
متن کاملProtective immunity in macaques vaccinated with live attenuated, recombinant, and subunit measles vaccines in the presence of passively acquired antibodies.
The presence of maternal antibodies is one of the main causes of measles vaccine failure. To evaluate the interference of passively acquired antibodies with vaccine efficacy, macaques (n = 16) were vaccinated with live attenuated measles vaccine in the presence or absence of passively acquired measles virus-specific monkey serum antibodies. As little as 0.1 IU of virus-neutralizing antibody/mL ...

Near-critical and supercritical fluids have been used successfully in the manufacture of vaccine, antibody and antibiotic microparticles by Carbon-dioxide Assisted Nebulization with a Bubble Dryer ® (CAN-BD). In CAN-BD two fluid streams, a drug, antibody, or vaccine solution or suspension, and supercritical or near-critical CO2, are intimately mixed in a low dead volume tee. These mixed fluid s...
