Live Last hour of the coronavirus
The level of protection of the booster doses of the Pfizer and Moderna vaccines against covid-19 decreases after four months but
is still effective in avoiding hospitalizations due to omicron,
according to a study published this Friday by the United States health authorities.
The Centers for Disease Control and Prevention (CDC) concluded that the effectiveness of braces in avoiding hospital admission is
91% during the first two months
of its application, but after four months it is 78% .
According to the study, five months after the third dose, the level of protection would drop to 33%, although the CDC admitted that they still do not have enough data on this group of people.
Therefore, the agency opened the door to
"consider" the recommendation of other additional doses
in order to maintain protection against hospitalizations.
The CDC currently recommends that everyone over 12 years of age receive a booster dose of the vaccine five months after completing their vaccination schedule in a country where
only 63% of the population has been vaccinated with both doses.
The United States is
the country most affected by the coronavirus
with more than 77.5 million confirmed cases since the start of the pandemic in March 2020 and more than 917,000 deaths, according to numbers from Johns Hopkins University.
After breaking historical records in January, contagion levels have been declining for several weeks in the country, although
deaths continue to rise,
with more than 3,000 deaths per day.
Hospital admissions have fallen in the last week, although they remain high, with a daily average of 13,000.
