A study was conducted in Singapore on the efficacy of mRNA vaccines against the delta variant of MERS-CoV. Health Minister Ong Ye Kung announced on Wednesday that full COVID-19 immunization with Moderna and Pfizer formulations provides 69 percent protection against Delta infection.
The minister also said that two doses of the vaccine protect against COVID-19 symptoms with an efficacy of “between 80 and 90 per cent”. Research by the National Center for Infectious Diseases (NCID) and the Department of Health also shows that 93 percent of formulations are to prevent severe illness and death. Kenneth Mack, MD, director of medical services, reported that vaccinated patients developed asymptomatic or mildly symptomatic delta variants.
The study lasted from September 2020 to May this year. A thousand families were analyzed where one person was diagnosed with the Corona virus.
This is another study on the effectiveness of vaccines against the delta variant
Singapore’s Straits Times notes that the results are consistent with analyzes conducted in other countries. For example, a study in Israel found that the Pfizer/BioNTech vaccine prevented delta infection with a 64% effectiveness.
