The latest series of studies show that the Moderna's Covid-19 vaccine seems to be effective for long-term injections than Pfizer.

The Centers for Disease Control and Prevention (CDC) in the United States announced the research results of more than 3,600 people hospitalized with a serious situation due to Covid-19 from March 11 to August 15.

This heading consists of 12.9% of full vaccination vaccines Moderna, 20% of Pfizer Vaccine and 3.1% inject a johnson & Johnson vaccine.

The research process indicates that the Vaccine Moderna effectively prevents the risk of hospitalization of 93%, while this figure at Pfizer and Johnson & Johnson vaccine is 88% and 68% respectively.

The researchers also concluded that Moderna's vaccine maintained the effectiveness of a hospitalization of 92% after more than 120 days of secondary injections.

Some other studies were conducted in Qatar, Mayo Clinic in Minnesota, some American states also had similar results.

The protection capability of the two vaccines decreases over time, especially before the appearance of the Delta strain, but the effect of the Pfizer vaccine seems to decrease more.

There are very small differences but still exist between Moderna and Pfizer.

The difference between the effectiveness of Vaccine Moderna and Pfizer can be related to dosages and distances of two injections.

However, many experts also argue that further research is needed to determine whether the effectiveness of Covid-19 vaccines is affected by the age or health condition of the person who is vaccinated.
