The forced mandatory vaccination of medical personnel with drugs from SARS-CoV-2 made it possible to assess the degree of “reliability” of Pfizer and Moderna in real conditions.

Scientists conducted a study based on data from 25 centers in the United States. Positive cases were determined based on the PCR test result or antigen test for SARS-CoV-2 and at least one symptom associated with COVID-19. Subjects in the control group had a negative PCR result for SARS-CoV-2, regardless of symptoms.
Vaccination efficacy was determined both 14 days after the first dose and 6 days after the second dose (partial vaccination) and at least 7 days after the second dose (complete vaccination).
This study included 1482 positive cases of COVID-19 (patients) and 3449 people in the control group. The partial vaccination efficacy was 77.6% with BNT162b2 (Pfizer / BioNTech) and 88.9% with mRNA-1273 (Moderna).
The efficacy with complete vaccination was 88.8% with the BNT162b2 vaccine (Pfizer / BioNTech) and 96.3% with the mRNA-1273 vaccine (Moderna).
The researchers summed up the results: mRNA vaccines against SARS-CoV-2 are very effective in real-world settings for preventing COVID-19 in healthcare workers. It is especially important that protection also applies to individuals at risk of serious illness, as well as to “vulnerable” groups of people with underlying severe chronic illnesses.
