One dose of COVID vaccine reduces the spread, research shows | Coronavirus News Plague


A new Public Health England study reveals that eagles are produced by Pfizer-BioNTech and AstraZeneca.

Just one dose of the coronavirus vaccine introduced in England could reduce the prevalence of COVID-19 in families by as much as 50 percent, released from a new study Wednesday.

A Public Health England (PHE) study found that those who became infected three weeks after receiving their first jab of Pfizer-BioNTech or AstraZeneca vaccine were between 38 and 49% less likely to transmit the virus to their families compared to others who had not been vaccinated.

The shot also stops a vaccinated person with pre-existing disease, reducing their risk by approximately 60-65% from four weeks after receiving the same dose.

These findings provide new insights into the uncertainties of the COVID-19 vaccine – how it inhibits the spread of the virus – and could prompt British Prime Minister Boris Johnson’s case to lift all of England’s sanctions in mid-June.

UK Health Secretary Matt Hancock was quick to acknowledge the results and urged people to continue to come for vaccinations after being shot by health officials.

“We already know that vaccines save lives and this study is the most well-known evidence that it also reduces the spread of the virus,” Hancock said in a statement.

“It is also encouraging that vaccination is the only way to prevent the epidemic because it protects you and can protect you from infecting someone in your home unknowingly,” he added.


The PHE study included 57,000 contacts from 24,000 families in which there was a formal problem with the COVID-19 vaccine-receiving lab, compared with nearly one million people who did not receive the vaccine.

Mary Ramsay, head of vaccination at PHE, described the findings as “very encouraging” and called on those who had been vaccinated to continue taking precautions to reduce the spread.

“Even if you have been vaccinated, it is important that you continue to act if you are HIV positive, keep your hands clean and follow the instructions to destroy people,” he said.

Naomi Forrester-Soto, a virologist at UK’s Keele University, also received her findings with a PHE as “extremely reliable”.

“We are not sure if the vaccine will be able to reduce the total spread, so this seems to be working with only one standard vaccine for Pfizer-BioNTech or AstraZeneca and good news,” Forrester-Soto told Al Jazeera.

He added that the study could be an important development initiative “to help people understand that taking vaccines also protects the people who care for them”.

The UK has one of the fastest COVID-19 vaccines in the world. At least 34 million adults have received the first vaccine so far and a quarter of all adults have been vaccinated.

Prompt vaccination work has quickly revealed the realities of how Pfizer and AstraZeneca shots work outside of clinical trials, and earlier this month PHE said the publication banned more than 10,000 people in their 60s and beyond by the end of March.
