BOSTON – A new study suggests that the protection that the Moderna vaccine provides against COVID-19 lasts for at least six months.
Tuesday’s report in the New England Journal of Medicine reflected what Pfizer said last week about its vaccine, which works in a similar way.
Both reports are based on follow-up tests on dozens of people who received gunshots during studies that led to the use of vaccines. These studies were performed before new variants or versions of the coronavirus appeared and began to spread.
EXPECTED EXPECTATION FOR ADULTS TO BE AVAILABLE FOR VACCINES AVAILABLE FOR VACCINES
A separate report in the medical journal adds concern about the options. The researchers measured antibodies that could block the virus in 50 people who received Sinopharm or Sinovac vaccines developed in China. Many showed complete or partial loss of efficacy against a viral variant first discovered in South Africa.
