Research found that Moderna COVID-19 vaccine can last at least 6 months



New research shows that the protective effect of Moderna vaccine against COVID-19 lasts for at least six months.

The report published in the New England Journal of Medicine on Tuesday echoed what Pfizer said last week about its vaccine, which is similar in effect.

Both reports are based on follow-up testing of dozens of people who were injected with the vaccine during the study, which led to the use of the vaccine. These studies were carried out before disturbing new variants or versions of the coronavirus appeared and began to spread.

Another report in the medical journal increased the focus on these variants. The scientists measured the antibodies that prevented 50 people from receiving the Sinopharm or Sinopharm vaccine developed in China. Many viruses have shown complete or partial loss of efficacy against virus variants first discovered in South Africa.

The vaccine still seems to protect against the variant originally discovered in the UK, which is now spreading rapidly in the US and elsewhere.

Pfizer and Moderna said that they are working to update the vaccine, or may design a booster injection, just in case a vaccine against the variant is needed.
