Re: Covid Johnson & Johnson Vaccinations in San Diego

There is no evidence that the Johnson & Johnson vaccine for covid-19 is inferior to the Moderna or Pfizer vaccines.


All three of the vaccines that are available in the United States do three things that are most important: 1. they prevent serious illness 2. they prevent hospitalizations 3. they prevent death.
In the clinical trials all of these vaccines were 100% effective in preventing the three most serious complications we all want to avoid.


The Moderna and Pfizer vaccines were developed during the early phase of the pandemic in this country and the Johnson & Johnson vaccine was developed later during the course of the pandemic.


The efficacy measurement was done differently between the Johnson & Johnson vaccine versus the Pfizer and Moderna vaccines. The Pfizer and Moderna vaccines efficacy endpoint was symptomatic disease, the J&J vaccine efficacy was whether or not you contracted covid-19 on a test nasal swab with a PCR gold standard test for the diagnosis.


These vaccines were not tested head to head, but they were all 100% effective in preventing serious illness, hospitalization and death.


As of April 13th, the Centers for Disease Control and the Food and Drug Administration recommended placing a hold on the use of the Johnson & Johnson vaccine due to an extremely rare complication affecting just six people out of 6.8 million vaccinated, all women between the ages of 18 and 48. We await further guidance from the CDC & FDA.
