Kaiser Permanente research study shows 3 dosages of Moderna COVID-19 vaccine extremely effective versus hospitalization from omicron or delta.
New Kaiser Permanente research released on February 21, 2022, in Nature Medication shows that while Moderna COVID-19 vaccine security is strong versus coronavirus infection by the delta version, it is not as strong against infection from the omicron variation.
3 doses of the Moderna COVID-19 vaccine were extremely effective versus hospitalization brought on by infection from either the omicron or delta version.
This study was carried out within the racially and ethnically varied subscription of Kaiser Permanente in Southern California utilizing specimens gathered in between December 6 and December 31, 2021.
It included 26,683 clients who checked favorable for COVID-19, 16% of whom had delta infections and 84% of whom had actually omicron infections, and more than 67,000 people who evaluated unfavorable as a contrast group. Specimens were primarily collected utilizing nasopharyngeal or oropharyngeal swabs for individuals with COVID-19 signs and saliva for people who did not have symptoms.
2 dosages of the Moderna COVID-19 vaccine were 44% efficient versus omicron infection within 3 months after vaccination, and efficiency quickly declined thereafter.
Three dosages of the Moderna COVID-19 vaccine within 2 months of vaccination were 94% effective against delta infection and 72% reliable against omicron infection.
For individuals who had compromised immune systems, 3-dose effectiveness versus omicron infection was lower at 29%.
The 3-dose efficiency versus hospitalization with delta or with omicron was above 99%.
” Our outcomes recommend that third dosages might be needed earlier than 6 months after the second dose of the Moderna COVID-19 vaccine to safeguard versus omicron infection,” said Hung Fu Tseng, PhD, a researcher with the Kaiser Permanente Southern California Department of Research & & Evaluation and a professors member of Kaiser Permanente Bernard J. Tyson School of Medicine, both located in Pasadena, Calif. “And that 3 dosages may be inadequate to secure individuals who are immunocompromised from omicron infection.”
He included: “Reassuringly, 3 doses supply strong protection versus COVID-19 hospitalization due to either the omicron or delta variant.”
