Recent research from the UK found that the Pfizer type of COVID-19 vaccine from BioNtech has a high potential to protect the body from transmission of the virus with a potential of up to 72 percent. Now, the UK is focused on expanding the dose 1 vaccination.
This research was conducted by Public Health England (PHE) to health workers under 65 years of age. Workers who have received the vaccine are then asked to do a PCR test every 2 weeks and a health check for asymptomatic risks.
“Overall, we found a very strong effect for reducing any risk, without symptoms (asymptomatic) and with symptoms (symptomatic),” explained the strategic response director at PHE, Dr Susan Hopkins, reported CNN, Tuesday (23/2/2021) ).
As for the people who received the second dose of the vaccine, it was said to have the potential to be protected from infection by up to 85 percent.
Through its research, PHE also suggests that one dose of Pfizer vaccine in the elderly has an effectiveness rate of 57 percent after injection of the first dose. However, after injection of the second dose with an interval of 4 weeks from the first injection, the effectiveness increased to 80 percent.
Previously, a number of studies showed that the function of vaccines is to reduce the risk of death in people infected with the COVID-19 virus. Or at least, reduce the risk of having to be hospitalized.
“The good sign is that overall, we are starting to see a reduction in hospitalizations and deaths from vaccination,” said head of immunization at PHE, Dr Mary Ramsay.
But with its new findings, PHE predicts the Pfizer vaccine could protect people from the risk of more severe disease by up to 57 percent after the first dose of injection.
With this in mind, the UK is now focusing on giving dose 1 vaccine to as many people as possible, with a priority for people at high risk of infection.
