Health desk -29 April 2021: A study showed that a single dose of the coronavirus vaccine can reduce the spread of the virus in the family by as much as half.
PHE found that those who received the first dose of Pfizer or AstraZeneca vaccine and were infected three weeks later reduced the likelihood of virus transmission by 38% to 49% compared with people who were not vaccinated.
Health Minister Matt Hancock described the results of the study as “great news.”
He urged “everyone to be vaccinated as long as they are eligible.”
PHE said in a statement that in this study, the Covid virus can be prevented from about 14 days after vaccination, and the level of protection is similar regardless of the age of the person or the age of the contact.
It added that this protection is the first to reduce the risk of symptomatic infection in the vaccinated person, which is about 60 to 65%-four weeks after a single dose of both vaccinations.
Dr. Mary Ramsay, Head of PHE Immunization, said: “Vaccines are essential to help us return to a normal lifestyle. Vaccines can not only reduce the severity of the disease and prevent hundreds of deaths every day, we now see that they also have a further reduction in the number of deaths. Covid-19 is an opportunity to pass on to others.”
But even though she said the results of the study are “encouraging,” she said it is important for people to continue to take action, as if they were infected with the virus, “to maintain good hand hygiene and follow the guidelines to stay away from society.”
PHE said that the home is a high-risk transmission site, which means that the study provides early evidence for the impact of vaccines in preventing continued transmission.
It added that similar results can be expected in other environments with similar transmission risks, such as shared accommodation and prisons.
