The COVID-19 vaccine can reduce the risk of contracting the virus, but once infected, the ability to transmit the virus to another person remains the same as that of an unvaccinated carrier.
Vaccination as a carrier of the virus
A recent study published in the journal Lancet Infectious Diseases It was released, and it showed Especially the delta variable It can easily pass from a vaccinated person to another person in the family.
Of the 621 household admixtures who participated in the study, 205 developed a delta variant. 38 percent of those infected were not vaccinated, while 25 percent were vaccinated. Doctor. Anika Singanayagam, co-author of the study, explains:
By frequent and frequent sampling of people in contact with cases of COVID-19, we have found that vaccinated people can become infected and transmit the infection within the household, including vaccinated family members.
The results also show that those who were vaccinated and tested positive for COVID-19 were vaccinated earlier than those who tested negative – supporting the theory that immunity decreases over time.
The authors therefore state that the only way to “increase the immunity of the population” is through “revitalization and youth vaccination programmes”.
Understand how to send
In addition, the study provides researchers with important insights into how the virus is able to spread among heavily vaccinated populations such as the United Kingdom. Doctor. Singanayagam adds:
Our results provide important insights into…why the delta variant continues to cause high numbers of COVID-19 cases around the world, even in countries with high vaccination rates.
The country is currently facing a new wave of cases, with nearly 300,000 cases reported in the past seven days. Hospital admissions are also on the rise: during the same period, 6,999 patients were admitted to medical facilities.
But despite the seemingly dire situation, politicians are using vaccines to slow transmission in the UK – a strategy many health experts believe will not be enough to control the virus over the winter.
