Even A Single Dose of COVID-19 Vaccine Can Reduce Infections: Study

Spread the love

A new real-world study accompanied by the Public Health England (PHE) has

announced that a single dose of COVID-19 vaccine can decrease the risk of

overdrive of the viral infection by half in a household setting. The study is the

most extensive research into the effects of vaccination because a household

setting is deemed a high-risk setting for Coronavirus communication among family

members. According to the study, people who tested positive for COVID-19 three

weeks after taking the first dose of the Oxford/AstraZeneca and BioNTech/Pfizer

vaccines were up to 49% less likely to transmit the virus to other parts of their

household concerning unvaccinated people. The AstraZeneca and Pfizer vaccines

began giving protection around two weeks after initial doses, offering similar levels

of protection regardless of the age of the vaccinated individuals. The initial doses

of both vaccines also reduced the risk of developing an asymptomatic infection by

65% within four weeks after vaccination. During the study, PHE compared the

vaccination status and household contact data of 57,000 contacts from 24,000

households in which at least one person had received the first dose of either

vaccine with nearly 1 million contacts of unvaccinated persons.

Head of Immunization at PHE, Dr. Mary Ramsay, has said that apart from decreasing

the severity of the infection and preventing hundreds of deaths daily, the

AstraZeneca and Pfizer vaccines are highly efficient in reducing the risk of

spreading COVID-19 infection to others. While terming the verdicts of the study

‘encouraging,’ Dr. Ramsay urged vaccinated people to continue following good

hand hygiene and following social-distancing guidelines.
