Coronavirus reinfections are rare, but it is more common for people aged 65 and over to become infected more than once. This is according to a study published in the Lancet Medical Journal on Wednesday.
The study, which looked at reinfection rates in 4 million people in Denmark, found that most people with Covid-19 appear to have been protected from re-infection for more than six months. In a six-month follow-up, the study found no evidence that protection was deteriorating. However, a demographics review of who was re-infected found that it was mostly people 65 and over, Jen Christensen reports.
The older age group only had about 47% protection against repeated infections, compared to younger people who appeared to have about 80% protection against re-infection, the team wrote. The finding is not entirely unexpected, as the immune system weakens with age.
“Given what it’s all about, the results underscore the importance of people taking steps to protect themselves and others, even after they’ve had COVID-19,” said study co-author Dr. Steen Ethelberg from the Statens Serum Institute in Denmark said in a statement.
This advice is being ignored in some parts of the US where governors are lifting measures to prevent it from spreading. Although almost one in eight Americans is fully vaccinated, the country could be on the verge of a second surge after the seemingly declining case numbers of recent weeks seemed to have leveled off.
Earlier this month, Chicago officials increased the capacity of bars, restaurants and other businesses indoors, while Baltimore officials said yesterday they would ease restrictions on places such as religious establishments, retail stores, shopping malls and fitness centers.
“We are in a race to vaccinate the population,” said Dr. Richard Besser, former acting director of the Centers for Disease Control and Prevention (CDC), told CNN on Wednesday. “At the same time, we are fighting the exhaustion of people with the restrictions that public health has put in place, and we are fighting the move by so many governors to remove the restrictions that protect us all.”

Q: I have a high BMI and I qualify for the vaccine. Does that mean I’m unhealthy?
ON: Since obesity is a factor in eligibility for Covid-19 vaccines, many Americans struggle to find out their body mass index, or BMI. However, experts say the meaning of these numbers – and how to lower them – isn’t always that straightforward.
The CDC lists obesity as an underlying condition and defines it as someone with a body mass index between 30 and 40.
A BMI over 30 can lead to serious health problems such as diabetes and cardiovascular disease, and obesity increases the risk of a more severe reaction to Covid-19.
However, having a high BMI doesn’t necessarily mean you are unhealthy. There are some rare instances when a healthy person can have a seemingly unhealthy BMI. This includes strength trainers and people with athletic physiques who have a lot of muscle and achieve a high BMI, said Dr. Caroline Apovian, co-director of the Weight Management and Wellness Center at Brigham and Women’s Hospital in Boston, Massachusetts.
If you’re unsure whether your high BMI is due to fat or muscle, Apovian recommends seeing a weight loss specialist for more specific testing.

WHAT’S IMPORTANT TODAY?
Covid-19 displaced hundreds of Africans from Guangzhou. A generation of mixed race children is their legacy
At the turn of the 21st century, the Chinese city of Guangzhou – already a magnet for internal migrants – became a fortuitous experiment of multiculturalism in China as loose immigration rules and factories producing cheap products attracted crowds of African entrepreneurs. Business was booming and by 2012 100,000 sub-Saharan Africans had already come to the city, making it the largest African expat community in Asia, Jenni Marsh reports.
But the pandemic displaced hundreds of Africans from the city, sparked the worst racist clashes against blacks in China in decades, and restored business operations, with Chinese factories connecting directly to African customers through e-commerce platforms. Those who stay are rooted there because of their Chinese partners and children.
The EU continues to attack AstraZeneca as it reveals vaccination records
The President of the European Commission, Ursula von der Leyen, attacked AstraZeneca for alleged underproduction and underdelivery, blaming her in part for the slow introduction of vaccines in Europe.
This is happening as the EU Medicines Agency prepares to issue guidelines on the safety of the vaccine after many countries suspended its introduction after reports of blood clots. The regulator has already said there is no evidence of a link between the AstraZeneca shots and clots.
Von der Leyen stressed that she trusts the Oxford / AstraZeneca Covid-19 vaccine, but warned that an export ban that the EU introduced in its recent dispute with the pharmaceutical company could be applied if other countries failed to export enough vaccines .
The EU has also presented its proposal for a “Digital Green Certificate” or vaccination certificate to allow safe and free movement within the bloc during the pandemic. The certificate confirming that a person has been vaccinated against Covid-19, received a negative test result or has recovered from Covid-19 can be used in all 27 member states.
Tanzania’s president, who undermined his country’s Covid-19 response, has died
After the President of Tanzania, John Magufuli, dismissed the severity of Covid-19, he died of heart disease in a hospital in Dar es Salaam. At the start of the pandemic, Magufuli urged citizens to “pray away the coronavirus,” saying the “satanic virus could not live in the body of Jesus Christ” and blaming faulty test kits for the growing number of positive cases.
In June, he claimed his country eradicated the coronavirus “by the grace of God”, questioned the safety of foreign Covid-19 vaccines and made no plan to procure any shots for his country, but rather to use herbal medicines and steam treatments to urge. Tanzania has not reported any Covid-19 numbers since April 2020, prompting the World Health Organization to urge the East African country to release data and move forward with public health measures.

Many states make people with a certain BMI eligible for vaccines. But because weight has such a stigma, getting in for an appointment may not be as easy as it sounds. CNN’s chief correspondent, Dr. Sanjay Gupta, hears from a staff member about her personal experience with vaccination and the complex relationship between weight and health. Listen now.
