Astra Geneca and Pfizer – Biontech’s Govt-19 vaccine halves the risk of infection at home, according to a British study.


Vaccines against Govt-19 do more than just protect against disease. They also halve the risk of infections at home – even after a single dose.

The United Kingdom is the most advanced country in Europe in vaccinating its population, where researchers and officials are now closely following the effectiveness of vaccines, in turn exploring other European countries. Anders Technell, a state epidemiologist, not from Sweden, has repeatedly cited experiences from the UK and Scotland in various conclusions regarding Swedish vaccines.

Recent data from the UK Public Health Agency currently show that the Covit-19 vaccine not only protects against the disease but also reduces the risk of transmission from person to person, the effect of which has not been fully elucidated before.

– Vaccines are very important in our search for a return to normal life. Vaccines not only reduce the risk of serious illness, but also save hundreds of lives each day, and we now see that they affect the risk of transmitting Covid-19 to others, says Mary Ramsay, head of vaccinations for public health UK, responsible for the BBC News.

Vaccines as of March show an estimated 10,400 lives among Britons over 60 years of age.

Reduced risk

The study now presented found that there were 57,000 contacts in 24,000 different households. In addition, one of these households received the Govit-19 vaccine from Pfizer-Biontech or Astra Geneca. The researchers examined whether the vaccinated person was infected, and if so, whether he or she had transmitted the infection to someone else in the household, which was defined as a positive test within 14 days of the vaccinated person being tested positive. The effect was comparable to that of nearly one million contacts with those in non-vaccinated households.

The results show that vaccinated people have a 38 to 49 percent lower risk of contracting the disease. The protective effect was observed 14 days after vaccination and was the same regardless of the age of the vaccinated person.

This study has not yet been subjected to regular scientific review (Peer Review), but is still seen as a great success. Despite this, Mary Ramsay urges everyone to behave as if they have the virus, i.e. in the UK – as in Sweden – you should recommend washing your hands, keeping your distance and reducing the number of social interactions. As much as possible.

The last part of the puzzle

In addition to workplaces and community gatherings, our own home is seen as one of the most vulnerable places by Govt-19.

According to observers, the results of the study mean that the last part of the puzzle is now in place. Vaccines not only protect against disease, they also reduce the spread of infection.

Mike Tildesley, an epidemiologist at the University of Warwick in the UK, told the BBC News that the study was encouraging, but that in order to reduce the spread of the disease, it was important to vaccinate as many people as possible. Possibility.

– We need to remember that vaccines are not 100 percent effective, against suffering from severe symptoms or transmitting the infection to others, he says.
