The American drug manufacturer Moderna wants to launch a single booster vaccination within two years that protects against both corona and flu, reports The Guardian .
CEO Stéphane Bancel expects that the combination vaccine – against corona, influenza and the common respiratory virus RSV – could be available before the contagious winter season of 2023.
“Our goal is to have a single annual booster so we don’t have adherence issues when people don’t want to get two to three injections per winter,” he said during a panel discussion at the World Economic Forum in Davos. Bancel hopes that the new drug will be ready for use in the fall of 2023.
The Moderna CEO has previously said that people may need a fourth vaccination this fall, as the protection provided by booster shots decreases in the coming months. In Israel, the first country in the world to allow people 60 years and older to receive a fourth dose of the corona vaccine.
The chief medical adviser to the US president, Anthony Fauci, said in Davos Monday there was no evidence that repeated boosters can overload the immune system. “There is no evidence that giving boosters at different times will disrupt the immune system’s response.”
