Boston – New research suggests that the Moderna vaccine against COVID-19 lasts at least 6 months.
A report Tuesday in the New England Journal of Medicine echoed what Pfizer said last week about the vaccine, which works the same way.
Both reports were based on follow-up tests on dozens of people who received images during the study, leading to the vaccine. These studies were conducted before the new, troubled corona virus emerged and began to spread.
BIDEN is expected to postpone the deadline for adults to be eligible for the vaccine.
A separate report in the medical journal raises concerns about the variables. Scientists have measured anti-virus antibodies in 50 people who received the Sinopharm or Sinovac vaccine developed in China. Many of them showed total or partial loss of efficiency to the virus first detected in South Africa.
CDC: There is a 1 in 1,000 chance of getting COVID-19 from the environment.
The vaccine also appears to protect against a variant first discovered in the UK, which is now spreading rapidly in the United States and elsewhere.

Pfizer and Moderna said they were working on improving their vaccines, or they could design a booster shot in case it needed to be used with variants.
