, must wait three weeks —after its administration— to be protected, since the body develops its immune capacity during that time,
During those weeks, the body will generate antibodies and a cellular response that consists of the production of lymphocytes. That means special white blood cells which protect people from the virus, she told Andina news agency.
Although being immunized means being better protected from the coronavirus, Solari reminded citizens that vaccines are not 100% effective.
According to the physician that of
Pfizer is 95% effective in preventing infection, while those of
Sinopharm and
AstraZeneca are 80%.
In terms of its effectiveness in preventing severe infection and death from COVID-19, the
Pfizer vaccine reaches 99%, while those of
Sinopharm and
AstraZeneca range between 85% and 90%.
It is important to know that since clinical studies show that the immune response decreases at ages 70, 80 and 90, just as vision is lost as the years go by.
Yet it does not mean that the elderly population needs more vaccines, but that they must continue to take care of themselves despite being vaccinated against coronavirus.
The INS infectologist pointed out that —by preventing severe disease with vaccines— there will be ICU beds for those who are not yet immunized and fall ill. In addition, there will be greater coverage of beds to care for patients suffering from other diseases.
Greater and faster coverage
Solari also expressed concern about the figure, noting that the vaccination rate is slow and needs to be improved. The United States, for example, has 50% of its population protected and is boosting strategies to reach out to people who resist immunization.
