The country has a large part of the vaccinated population, however, it is mired in a health crisis.
“In order to Chile and for all countries, they must take into account that vaccines are a very powerful tool, but that other measures must also be applied which can prevent infections, reduce the spread and that those who are infected do not develop disease. serious illness and die, “said the head of the technical unit against the coronavirus of the WHO, Mara Van Kerkhove.
“It takes time for vaccines to have the impact we all expect, first reducing morbidity and mortality and then having an impact on reducing transmission,” he added.
The chief scientist of the WHO, Soumya Swaminathan, he said, people forget that vaccines are fully effective two weeks after the second dose.
In addition, a very high level of vaccinated people (between 70 and 80%) is needed to “start building collective immunity, from which you start to see a significant reduction in the transmission of the virus”.
Swaminathan record that no vaccine offers 100% immunity, although they reduce the risk of contagion, in some cases by up to 95%.
“There is a normal tendency in people who have been vaccinated to lower their guard, stop wearing the mask or keep their distance from others, so this is like a wake-up call for countries where vaccination is well advanced, but they haven’t reached the point where people can really relax, ”he commented.
