Does Being Fully Vaccinated Mean You Cannot Spread COVID At Home?

Since households are where most Covid transmission occurs, making sure every member who is eligible for a vaccine has had one and is up to date with their doses makes sense, say experts.

What did the study entail?

It ran from September 2020 to September 2021 and included 440 households in London and Bolton doing PCR Covid tests. It found that….

According to Prof Ajit Lalvani, of Imperial College London, UK, who co-led the study, “The ongoing transmission we are seeing between vaccinated people makes it essential for unvaccinated people to get vaccinated to protect themselves from acquiring infection and severe Covid-19, especially as more people will be spending time inside in close proximity during the winter months. We found that susceptibility to infection increased already within a few months after the second vaccine dose – so those eligible for booster shots should get them promptly.”

“Our findings provide important insights into the effect of vaccination in the face of new variants, and specifically, why the Delta variant is continuing to cause high Covid case numbers around the world, even in countries with high vaccination rates. Continued public health and social measures to curb transmission such as mask wearing, social distancing, and testing – thus remain important, even in vaccinated individuals,”co-author Dr Anika Singanayagam, also from Imperial was quoted as saying.
