Two new studies from the United States and the United Kingdom have provided further evidence that booster doses of COVID-19 vaccine reduce the risk of hospitalization and death.
The UK Health Insurance Agency (UKHSA) said booster doses reduce the risk of death from the Omicron variant by 95 per cent in people aged 50 and older. This figure is higher compared to the findings that people of the same age group, who are vaccinated with two doses, have about 60 percent protection against death with Omicron six months after the last dose.
The agency’s data continued to show high levels of protection against hospitalizations with 90 percent of people taking the booster dose of Pfizer / BioNTech.
“The data are clear, the vaccine helps protect us all against the effects of COVID-19, and the booster dose offers high levels of protection against hospitalization and death in the most vulnerable members of society,” said Mary Ramsay, director for immunization at UKHSA.
In the United States, the Centers for Disease Control and Prevention (CDC) published a new study showing that a third dose of the Pfizer / BioNTech or Moderna vaccine significantly reduced the risk of hospitalization among people with weakened immune systems. .
The CDC said the study found that boosting doses provide 97 percent protection to people without chronic illness and 88 percent to those with chronic illness. This study was conducted last year, when the Delta variant of the coronavirus was dominant and also, according to the CDC is a data more than booster dose strengthens antibodies in people with stronger immune system.
