LONDON – New data have arrived to allay concerns about shortages of COVID-19 vaccines disrupting dosing schedules, and also answering the question of whether third – booster – doses will restore waning immunity and be effective against viral variants.
PERTH, Australia – Australia will be phasing out the Astrazeneca COVID-19 vaccine by October and will rely on Pfizer Inc./Biontech SE and Moderna Inc. vaccines to ramp up lagging vaccination rates.
Although the U.S. CDC considers myocarditis to be a rare event linked to mRNA COVID-19 vaccines, the FDA is adding a warning about the adverse event to its doctor and patient fact sheets for the vaccines.
LONDON – The Delta variant of SARS-CoV-2 originally identified in India is causing more serious illness and reducing the effectiveness of vaccines compared to the Alpha (Kent) variant, according to a nationwide study covering Scotland’s whole population of 5.4 million.
The good of the many versus the good of the individual is the age-old question that faced the FDA’s Vaccines and Related Products Advisory Committee (VRPAC) June 10 as it considered the risk-benefit issues of COVID-19 vaccines in children. Panelist Cody Meissner, director of pediatric infectious disease at Tufts Medical Center, said while he believes a vaccine is needed for children, he wants to know that the safety of the vaccine is greater than the risk of hospitalization for people younger than 18.
LONDON – A new U.K. study indicates the Pfizer Inc./Biontech SE COVID-19 vaccine is less effective against the India variant of the SARS-CoV-2 virus that was designated as of global concern by the World Health Organization (WHO) on May 10.
HONG KONG – In the midst of a COVID-19 crisis, India has waived the need for “well-established” foreign vaccines to undergo local trials. That could open doors for vaccines by Pfizer Inc., Johnson & Johnson and Moderna Inc.
With the global COVID-19 pandemic and variants raising expectations about the need for booster shots, more companies are jumping into the vaccine space. But unless those sponsors have been engaging “in an ongoing manner” with the U.S. FDA on developing the manufacturing process and clinical trial program for their vaccine candidates, their emergency use authorization (EUA) requests may be denied, according to a new FDA guidance on EUAs for COVID-19 vaccines.
Two weeks after Pfizer Inc.-Biontech SE’s mRNA-based COVID-19 vaccine received emergency use authorization (EUA) for adolescents ages 12 to 15, the first in that age group, Moderna Inc.’s mRNA vaccine has hit the primary immunogenicity endpoint in its phase II/III study of participants ages 12 through 17.
LONDON – The U.K. is launching a trial to investigate the potential use of seven different COVID-19 vaccines as boosters, to provide safety and immunogenicity data for if/when immune responses to initial vaccination wane and a revaccination campaign is needed later in the year. The trial, at 18 sites across the country, will recruit 2,886 participants who previously received two doses of either Astrazeneca plc or Pfizer Inc./Biontech SE’s COVID-19 vaccines.
