There are some COVID-19 vaccine Is it more effective than others?

They are difficult to distinguish because they were not directly compared in the study. But experts say vaccines are similar in terms of the most important thing: hospitalization and death prevention.

“Fortunately, all of these vaccines seem to protect us from serious illness,” said Dr. Monica Gandhi of the University of California, San Francisco, five of the world’s used vaccines. I quoted the findings of the vaccine and the sixth vaccine still under consideration.

And real-world evidence that millions of people are receiving vaccines shows that they are all working very well.

Still, studies conducted before the vaccine was deployed found different levels of efficacy, and people may wonder if one is better than the other. The problem is that they don’t provide a comparison between apples.

Pfizer and Modana double-dose vaccines have been shown to be approximately 95% effective in preventing disease. Studies of these shots counted whether cases of COVID-19 were mild, moderate, or severe, and were performed before the mutant virus of interest began to circulate.

The story continues below.

Later, Johnson & Johnson tested a single-dose vaccine and did not count mild illnesses. J & J’s shots were 66% defensive against moderate to severe illness in a large international survey. In the United States alone, where variants are less prevalent, there was a 72% effect. More importantly, the vaccine’s effectiveness prevented hospitalization and death.

The AstraZeneca two-dose vaccine used in many countries faces questions about the exact degree of its effectiveness shown by studies. However, experts agree that these shots are also protected from the worst results.

In countries where vaccines are deployed, such as Israel, the United Kingdom and Scotland, hospitalizations are declining worldwide, regardless of which shots are given. Also, when the U.S. government first looked at actual data on essential workers, further evidence that the Pfizer and Moderna vaccines were highly defensive (90%) against infection, with or without symptoms. Was obtained.
