What you need to know about coronavirus on Thursday, January 14

A new study led by Public Health England, a government agency, found that people who were infected with Covid-19 can have immunity to the virus for at least five months. The findings are preliminary and have not yet been peer-reviewed, but offer some guarantees to frontline healthcare professionals.

The researchers monitored nearly 21,000 health professionals across the UK between June and November and tested them regularly to see if they had been infected with Covid-19. Of those monitored, 6,614 people were diagnosed with the virus before, and among them, 44 developed possible new infections.

The study found that the previous infection reduces the chances of getting the virus again by 83% for at least five months, writes Zamira Rahim.

There are some important caveats to watch out for. The researchers warned that the protection is not absolute and that it is not clear how long the immunity lasts. It is also possible that those who have some degree of immunity against the virus are still able to pass it on to others. An initial look at the next stage of the study shows that some people with existing immunity carry high levels of viruses.

Science may seem complicated, but the implications for real life are not. You may be immune to the virus after recovering from Covid-19, but you should still wear a mask and practice social detachment to protect the people around you.

Q: How do Covid-19 vaccines work?

AN: Vaccines usually mimic part of the virus they protect against, prompting an immune system response. Covid-19 shots use different approaches.

Moderna and Pfizer vaccines use new technology. The vaccines deliver messenger RNA, or mRNA, which is a genetic recipe for making the spines on top of the coronavirus.

The AstraZeneca vaccine, developed with a team from Britain’s Oxford University, is called a vector vaccine. It uses a common cold virus called adenovirus to transport the coronavirus protein to cells. The Johnson & Johnson vaccine and Russia’s Sputnik V use a similar approach.

WHAT’S IMPORTANT TODAY

Two WHO scientists barred from entering China due to failed coronavirus antibody test

An international team of 13 scientists is due to land today in the city of Wuhan, in central China, where coronavirus cases were first recorded in late 2019. They are expected to investigate the origins of the pandemic, but two members of that team remain in Singapore. after they “tested positive for IgM antibodies,” said the World Health Organization. This is the second delay by the WHO team. IgM antibodies are among the first potential signs of a coronavirus infection, but they can also appear in someone who has been vaccinated or previously infected.
The news came at a time when China reported its first Covid-19-related death in 242 days and its new daily infections reached their highest levels since July.

Johnson & Johnson vaccine shows promise in early trials

Initial tests of the Johnson & Johnson experimental coronavirus vaccine show that it generated an immune response in almost all volunteers, with minimal side effects after a single dose. The company expects to report details of more advanced tests later this month and expects to seek authorization from the U.S. Food and Drug Administration shortly thereafter.
The vaccine would be the first single-dose vaccine to be approved in the United States. It uses a weakened version of a common cold virus to transport the virus’s genetic material into the body, causing human cells to produce pieces of the virus that are then recognized by the immune system.

Covid’s cases remain the lowest among younger children, even after schools reopened

A report by the United States Centers for Disease Control and Prevention found that Covid-19 cases among younger children remained low, even after schools restarted for personal learning. To reopen schools safely, however, transmission in communities must be controlled.

Why I lost on live TV

CNN correspondent Sara Sidner was unable to contain her tears while doing a live report on the coronavirus crisis in Los Angeles. Looking back at the moment, she writes: “I felt raw, exposed and ashamed at the same time. I was taught long ago as a woman ‘never let them see you cry’ – not in public and especially at work.

“What brought me to tears was, at first, simply anger. Anger at those who do not take our ills seriously and those who are actively fighting the truth. They are putting people’s lives in danger.”

BEST TIP

New Year’s resolutions often fade and die, unless you can turn them into habits. So we asked behavioral science expert BJ Fogg how to keep his good intentions.

One of his tips: if someone wants to exercise or thinks they should, the key is to find an exercise that makes them feel successful or that they find enjoyable – one or the other.
