agency have stated that reports show it is now possible to consider giving
booster doses of the Sinopharm vaccine.
While
protection against infection was evidenced to be low, the study concluded that
the vaccine is 94 percent effective in preventing death from COVID-19 infection
after receiving its two doses.
Almost
400,000 medical workers participated in the research study, which collected and
analyzed data from February to June, when Peru was battling a second wave of
the pandemic, worsened by the Lambda and Gamma strains.
The
majority of the medical staff received both doses of the vaccine.
The study,
which was published last week and cites scientists at the National Institute of
Health in Peru and two other research institutions, stated, “the efficiency of
infection prevention is not high, and this is something that must be considered
once a high percentage of the population is vaccinated with both doses of the
vaccine, then it is possible to consider giving booster doses to enhance the protection
of medical staff on the front lines of the pandemic.”
The Lambda
strain has made headlines lately due to its spread in the United States and
other Latin American countries, but infectious disease experts have said that
the spread of this strain may now be declining.
