Experimental COVID-19 vaccine protects upper and lower airways in nonhuman primates

Two doses of an experimental vaccine to prevent coronavirus disease 2019 (COVID-19) induced robust immune responses and rapidly controlled the coronavirus in the upper and lower airways of rhesus macaques exposed to SARS-CoV-2, report scientists from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. SARS-CoV-2 is the virus that causes COVID-19.

ConclusionThe MESV developed in this study is capable of generating immune response against COVID-19. Therefore, if designed MESV further investigated experimentally, it would be an effective vaccine candidate against SARS-CoV-2 to control and prevent COVID-19.

The cleverest of enemies thrive on surprise attacks. Viruses—and coronaviruses in particular—know this well. Remaining hidden in animal hosts for decades, they mutate steadily, sometimes serendipitously morphing into more effective and efficient infectious agents. When a strain with just the right combination of genetic codes that spell trouble for people makes the leap from animal to human, the ambush begins. Such was the case with SARS-CoV-2, the coronavirus behind COVID-19, and the attack was mostly silent and insidious at first. Many people infected with SARS-CoV-2 remained oblivious as they served as the v...

The last time most of us gave any thought to antibodies was probably in high school biology, but we’re getting a crash refresher course thanks to COVID-19. They are, after all, the key to our best defenses against SARS-CoV-2, the virus that’s caused the global pandemic. People who have been infected likely rely on antibodies to recover, and antibodies are what vaccines are designed to produce. Or at least that’s what infectious-disease and public-health experts assume for now. Because SARS-CoV-2 is such a new virus, even the world’s best authorities aren’t yet sure what it will take to build p...

This report updates the 2019-20 recommendations of the Advisory Committee on Immunization Practices (ACIP) regarding the use of seasonal influenza vaccines in the United States (MMWR Recomm Rep 2019;68[No. RR-3]). Routine annual influenza vaccination is recommended for all persons aged ≥6 months who do not have contraindications. For each recipient, a licensed and age-appropriate vaccine should be used. Inactivated influenza vaccines (IIVs), recombinant influenza vaccine (RIV4), and live attenuated influenza vaccine (LAIV4) are expected to be available. Most influenza vaccines available for the 2020-21 season will be qu...

It is a frightening time to live in the United States. COVID-19, a novel disease as ruthless as it is seemingly random, is picking us off by the thousands; even many of those who “recover” may never truly be the same again. The pandemic has exposed the gulf between what this country promises for its citizens and what it actually delivers. And as the U.S. barrels toward Election Day, the outbreak is sure to complicate the voting process, with potentially disastrous results. For a short time in the spring, it appeared the U.S. was getting a grip on its outbreak. Hard-hit states like New York successfully flattene...

CONCLUSION: In light of these unprecedented times, the need to understand the nuances of these viral respiratory pathogens, especially SARS-CoV-2, cannot be overemphasized. This knowledge base is of particular importance to otolaryngologists, whose expertise in the upper airway coincides with the anatomic tropism of these infectious agents.

Moderna Therapeutics and the National Institute of Allergy and Infectious Diseases (NIAID) announced today that researchers had injected the first volunteer in the first U.S. coronavirus vaccine to reach the final, phase 3 stage of testing. That person received the shot at 6:45 am eastern time in Savannah, Geo., Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases of the National Institutes of Health (NIH) told reporters during a briefing. Because the trial will randomly assign participants to receive either the vaccine or a placebo, and neither the researchers nor the volunteers will kn...

In a study published July 14 in the New England Journal of Medicine, researchers report on the results of the first COVID-19 vaccine to be tested in people. The trial, which involved 45 healthy volunteers, was designed to test the safety of the vaccine, but results offer early hints of its effectiveness. Moderna Therapeutics, the Mass.-based biotech firm that developed the vaccine along with researchers from the National Institute of Allergy and Infectious Diseases, first reported the results in a press release on May 18. The NEJM paper formally describes those results. The 45 participants, aged 18 to 55 years, were enroll...

Abstract The outbreak of the 2019 novel coronavirus (SARS-CoV-2) has infected millions of people with a large number of deaths across the globe. The existing therapies are limited in dealing with SARS-CoV-2 due to the sudden appearance of the virus. Therefore, vaccines and antiviral medicines are in desperate need. We took immune-informatics approaches to identify B- and T-cell epitopes for surface glycoprotein (S), membrane glycoprotein (M) and nucleocapsid protein (N) of SARS-CoV-2, followed by estimating their antigenicity and interactions with the human leukocyte antigen (HLA) alleles. Allergenicity, toxicity,...

Before the ravaging appearance of the severe acute respiratory syndrome coronavirus 2, influenza viruses have been among the major players in the history of health disasters over the past century.1,2 Because the 1918 Spanish flu pandemic claimed more than 50 million lives followed by annual resurgence of varying degrees of morbidity and mortality, the influenza vaccine program has driven platform development and global collaborative surveillance networks. These networks support the definition of antigenic shifts that drive annual vaccine specificities for manufacturing responses.
