Experts believe that the most important aspects of vaccines are similar: prevention of hospitalization and death
new York- Is there a Covid-19 vaccine that is more effective than other vaccines?
It is difficult to say, because they have not been directly compared in the research. But experts believe that the most important aspect of vaccines is similar: prevention of hospitalization and death.
Dr. Monica Gandhi of the University of California, San Francisco said: “Fortunately, all these vaccines seem to protect us from serious diseases.” The sixth place is still under review.
After millions of people were vaccinated, tests conducted in the real world showed that they all worked very well.
However, people still doubt whether one vaccine is better than the other, because studies conducted before the vaccines are distributed have shown varying degrees of effectiveness. The problem is that they do not provide equivalent comparisons.
For example, two doses of vaccines from Pfizer and Modena have been found to be about 95% effective in preventing diseases. The study of these drugs included a case of the Covid-19 virus, whether it was mild, moderate or severe, all completed before the worrying virus variants began to spread.
Later, Johnson & Johnson tested a dose of its vaccine and did not count minor illnesses. In a large international study, his drug has an effective rate of 66% for moderate to severe diseases. In the United States, where variants are less common, its effective rate is 72%. Most importantly, once the vaccine takes effect, it can prevent hospitalization and death.
The effectiveness data of the two-dose AstraZeneca vaccine study from many countries has been questioned. But experts also agree that these injections can prevent Covid-19 from having the worst effects.
In different parts of the world, no matter what type of vaccine they use, the rate of hospitalization in countries that start the vaccination (such as Israel, the United Kingdom, and Scotland) will drop. The U.S. government’s first review of basic workers who have been vaccinated provides new evidence that Pfizer and Moderna vaccines can provide a high rate of protection-90%-against infection, regardless of symptoms.
