New Study Compares Vaccines: Pfizer Versus Moderna

COVID-19 vaccinations from Moderna and Pfizer have shown to be extremely effective.
Scientists examined the differences in efficacy between the two vaccinations in a new study.
They discovered that those who got two shots of the Moderna vaccination were less probable than individuals who got the Pfizer vaccine to get COVID-19 or be admitted with the disease.

Moderna and Pfizer COVID-19 immunizations are both messenger ribonucleic acid shots, which are a fairly new form of vaccine science.

These COVID-19 vaccines function by instructing our cells to produce a SARS-CoV-2 protein. The immune system then responds to such protein and builds the capabilities needed to adapt to any prospective viral infection. The Centers for Disease Control and Prevention (CDC) scientists discovered that all the Moderna and Pfizer shots are quite successful in shielding people from COVID-19.

The most recent study looked at the variations in frequencies of “breakthrough” COVID-19 infections among persons who got the Moderna or Pfizer vaccinations. A breakthrough case occurs when the illness manifests itself in someone who has been completely immunized against it.


The researchers were also looking for any variations in the incidence of hospital admission and mortality owing to COVID-19 among those who got either immunization. The researchers used health information from 89 million individuals in the United States to conduct their study. People with a broad variety of demographic traits were included in the data.

The researchers examined data collected throughout July and November 2021, so when Delta form of COVID-19 was the predominant viral strain. People completely immunized with the Moderna vaccine had a decreased probability of hospital admission in the 60 days after infection: 12.7 percent for Moderna vs 13.3 percent for Pfizer.

There was no statistically meaningful variation in death rates among the different immunization groups, according to the scientists.

The study can be read in JAMA.
