(((WXIN) – Moderna released information this week showing that protection from the COVID-19 vaccine has diminished over time as US regulators are trying to determine the need for booster shots.
US pharmaceutical companies have shared information from a Phase 3 trial showing that recently vaccinated patients have a lower frequency of breakthrough cases.
Researchers said that in Moderna’s 2020 vaccine study, which was first vaccinated about a year ago, about 14,000 people were vaccinated about eight months ago last winter with another 11,000 people. I compared. Due to the surge in deltas in July and August, Moderna concluded that recently vaccinated groups had a 36% lower incidence of “breakthrough” infections than previously vaccinated groups. rice field.
According to Moderna data, there were 88 breakthrough cases out of 11,431 vaccinated between December 2020 and March 2021. The company identified 162 breakthrough cases out of 14,746 vaccinated between July 2020 and October 2020.
According to Modana, recently vaccinated individuals had fewer severe cases of COVID-19.
The company believes the results indicate the need for booster shots, as the effectiveness of the vaccine appears to decline over time. The analysis still needs to be peer reviewed.
Pfizer-BioNTech is also seeking approval for additional booster shots of the COVID-19 vaccine. The Vaccine Advisory Board of the major Food and Drug Administrations will meet this week to consider the need for booster shots in the United States.
Pfizer said protection against COVID-19 is in place in the United States. However, the company gave 306 additional doses 6 to 8 months after receiving the second dose. Booster shots have tripled the number of antibodies that fight the virus.
Support for booster shots varies. The Biden administration wanted to begin dose distribution on September 20, but the FDA has been cautious so far. The agency has the final say on the booster campaign and does not necessarily have to follow the recommendations of its advisory board. Booster Shot is approved for individuals with a weakened immune system.
