You May Have Antibodies After Coronavirus Infection. But Not for Long. (Published 2020)

Antibodies to the virus faded quickly in asymptomatic people, scientists reported. That does not mean immunity disappears.

Spain's coronavirus antibodies study adds evidence against herd immunity
From CNN's Al Goodman

Spain's large-scale coronavirus study indicates that just 5% of its population has developed antibodies, strengthening evidence that a so-called herd immunity to Covid-19 is "unachievable," medical journal the Lancet reported on Monday.

The findings show that 95% of Spain's population remains susceptible to the virus.

Herd immunity is achieved when enough of a population has become infected with a virus or bacteria -- or vaccinated against it -- to stop its circulation.

The European Center for Disease Control told CNN that Spain's research, on a nationwide representative sample of more than 61,000 participants, appears to be the largest study to date among a dozen serological studies on the coronavirus undertaken by European nations.

It adds to the findings of an antibody study involving 2,766 participants in Geneva, Switzerland, published in the Lancet on June 11.

There have been similar studies in China and the United States, and "the key finding from these representative cohorts is that most of the population appears to have remained unexposed" to Covid-19, "even in areas with widespread virus circulation," said a Lancet commentary published along with Spain's findings.

"In light of these findings, any proposed approach to achieve herd immunity through natural infection is not only highly unethical, but also unachievable," said the Lancet's commentary authors, Isabella Eckerle, head of the Geneva Centre for Emerging Viral Diseases, and Benjamin Meyer, a virologist at the University of Geneva.

Doctors are uncertain whether having antibodies to the coronavirus means someone cannot be infected again. It's not clear how long or how well antibodies protect people from the virus.

Spain's peer-reviewed study began in April while the nation remained on a strict lockdown, and was conducted by leading government research and epidemiological agencies.

Study suggests 13% of Londoners have coronavirus antibodies

Thirteen percent of Londoners have coronavirus antibodies, according to a study led by Imperial College London which surveyed more than 100,000 people across England. Those who tested positive for antibodies are likely to have previously contracted Covid-19,
Researchers found that antibody levels in London were over twice England's national average.

Just over 6% of tested people in the country overall had antibodies. The lowest antibody levels were detected in the nation's southwest region, where only 3% of people tested positive.

Key workers and health care employees were most likely to have previously had Covid-19, according to the study, which has not been peer reviewed.

Meanwhile Black, Asian and ethnic minority participants are between two to three times as likely to test positive when compared to their white counterparts.
Participants in the study used antibody finger-prick tests at home to participate.

"Using the finger-prick tests suitable for large scale home testing has given us clearest insight yet into the spread of the virus in the country and who has been at greatest risk," said Professor Graham Cooke, NIHR Research Professor of Infectious Diseases at Imperial.

"These data will have important implications for decisions around ongoing control measures in England.”

Aiming for Covid-19 herd immunity in the US would lead to massive death tolls, Anthony Fauci warns
From CNN's Faith Karimi

If the United States allowed coronavirus infections to run rampant to achieve possible herd immunity, the death toll would be massive, especially among vulnerable people, the nation's top infectious diseases doctor said.

Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases, explained the risks during a live Instagram session with actor Matthew McConaughey.

"If everyone contracted it, even with the relatively high percentage of people without symptoms ... a lot of people are going to die," Fauci said.

"You look at the United States of America with our epidemic of obesity as it were. With the number of people with hypertension. With the number of people with diabetes. If everyone got infected, the death toll would be enormous and totally unacceptable," Fauci added.

Sweden records highest death tally in 150 years in first half of 2020
From CNN's Hilary McGann

Sweden recorded its highest death tally in 150 years for the first half of 2020, according to the country’s official statistics office.

Between January and June this year, 51,405 deaths were registered in the country -- more than 6,500 fatalities (or 15%) over the same period in 2019.

This is the highest number of deaths in Sweden during the first half of the year since 1869, when the country was struck by famine and 55,431 people died.

The country also experienced the lowest population increase since 2005, with a surplus figure of 6,860 in 2020 that was less than half that of the previous year.

Immigration figures also saw a reduction of 34.7% from the same period in 2019, with the figures primarily dropping in the second quarter between April and June.

The background: Unlike most countries, Sweden did not go into a lockdown when the pandemic spread across Europe in early spring. Instead, there was an emphasis on personal responsibility, with most bars, schools, restaurants and salons remaining open.

By early June, the country’s coronavirus death toll was at more than 4,500. According to Johns Hopkins University, it now stands at 5,802.
