Imperial Covid study finds infection rate rises 3-6 months after vaccine dose

People most at risk from Covid-19 are being urged to have a booster vaccine after researchers discovered evidence of more “breakthrough infections” for those fully inoculated more than three months previously.

Experts on the Imperial College London-led React-1 study monitored home swab tests taken by more than 100,000 people in England between September 9 and 27 – 764 were positive for the virus.

Among those fully vaccinated, the prevalence of infection (0.55 per cent) was higher for those who had their second dose of vaccine three to six months ago, compared with those who had who received their second shot less than three months ago (0.35 per cent).

"We found more breakthrough [Covid-19] infections among those who received their second vaccine dose between three and six months ago than those whose second dose was less than three months ago,” said Christl Donnelly, professor of statistical epidemiology at Imperial.

“However, booster doses offer the prospect of increased protection, lowering population infection levels.”

The government is offering booster shots for those most at risk from Covid-19 who were given their last dose at least six months ago.

Health Secretary Sajid Javid said it was important that “those eligible to get their booster vaccine to prolong their existing protection. I urge anyone who needs one to get a jab as soon as possible – it’s vital to keep you and your family safe this winter.”

The study also found that cases were highest in school-aged children – one in 43 five to 12-year-olds, and one in 39 13 to 17-year-olds.

“Our latest data show that infections are high and rising in school-aged children. Households with children also had a higher prevalence of infection, suggesting that children may be passing on the virus to those they live with,” said Prof Paul Elliott, director of the React-1 programme.

“These trends reinforce how important it is for children aged 12 and above to get vaccinated and help curb the spread of infection, and minimise disruption to education.”

Mr Javid said the findings showed "how important it is for young people to get the jab".

Infections were more than twice as high in those unvaccinated compared with those who received two doses. Vaccine effectiveness against infection was 44.8 per cent for AstraZeneca and 71.3 per cent for Pfizer/BioNTech.

“As we move towards winter, it is as important as ever that we continue to act responsibly in order to avoid transmission,” said Dr Jenny Harries, chief executive of the UK Health Security Agency

“While cases remain high, the vaccination programme is ensuring that this does not translate to a similarly high number of hospitalisations and deaths.

"We are urging everyone who is eligible to come forward for vaccination. It is the best way to reduce transmission and protect ourselves and those we love.”

Top investing tips for UAE residents in 2021

Build an emergency fund: Make sure you have enough cash to cover six months of expenses as a buffer against unexpected problems before you begin investing, advises Steve Cronin, the founder of DeadSimpleSaving.com.

Think long-term: When you invest, you need to have a long-term mindset, so don’t worry about momentary ups and downs in the stock market.

Invest worldwide: Diversify your investments globally, ideally by way of a global stock index fund.

Is your money tied up: Avoid anything where you cannot get your money back in full within a month at any time without any penalty.

Skip past the promises: “If an investment product is offering more than 10 per cent return per year, it is either extremely risky or a scam,” Mr Cronin says.

Choose plans with low fees: Make sure that any funds you buy do not charge more than 1 per cent in fees, Mr Cronin says. “If you invest by yourself, you can easily stay below this figure.” Managed funds and commissionable investments often come with higher fees.

Be sceptical about recommendations: If someone suggests an investment to you, ask if they stand to gain, advises Mr Cronin. “If they are receiving commission, they are unlikely to recommend an investment that’s best for you.”

Get financially independent: Mr Cronin advises UAE residents to pursue financial independence. Start with a Google search and improve your knowledge via expat investing websites or Facebook groups such as SimplyFI.
