This piece by the Associated Press’ Daria Litvinova is really fascinating – there is an obsession with antibody tests in Russia even as vaccine takeup remains low – only 28% are fully vaccinated and cases are again rising.

Here’s a bit of an edited version:

When Russians talk about the coronavirus over dinner or in hair salons, the conversation often turns to “antitela,” the Russian word for antibodies – the proteins produced by the body to fight infection.

Even President Vladimir Putin referred to them this week in a conversation with his Turkish counterpart Recep Tayyip Erdoğan, bragging about why he avoided infection even though dozens of people around him caught the coronavirus, including someone who spent a whole day with the Kremlin leader.

“I have high titers,” Putin said, referring to the measurement used to describe the concentration of antibodies in the blood. When Erdoğan challenged him that the number Putin gave was low, the Russian insisted: “No, it’s a high level. There are different counting methods.”

But Western health experts say the antibody tests so popular in Russia are unreliable either for diagnosing Covid-19 or assessing immunity to it.

[…]

In Russia, it’s common to get an antibody test and share the results. The tests are cheap, widely available and actively marketed by private clinics nationwide, and their use appears to be a factor in the country’s low vaccination rate even as daily deaths and infections are rising again.

More interest in antibody testing came this summer when Russia had a surge of infections. The demand for tests spiked so sharply that labs were overwhelmed and some ran out of supplies.

That’s when dozens of regions made vaccinations mandatory for certain groups of people and restricted access to various public spaces, allowing in only those who were vaccinated, had had the virus, or had tested negative for it recently.

Daria Goryakina, deputy director at the Helix Laboratory Service, a large chain of testing facilities, said she believed the increased interest in antibody testing was connected to the vaccination mandates.

In the second half of June, Helix performed 230% more antibody tests than in the first half, and the high demand continued into the first week of July. Goryakina told The Associated Press:

People want to check their antibody levels and whether they need to get vaccinated.

Both the World Health Organization and the CDC recommend vaccination regardless of previous infection.

Guidance in Russia has varied, with authorities initially saying that those testing positive for the antibodies weren’t eligible for the shot, but then urging everyone to get vaccinated regardless of their antibody levels. Still, some Russians believed a positive antibody test was a reason to put off vaccination.

Maria Bloquert recovered from the coronavirus in May, and a test she took shortly after revealed a high antibody count. She has put off her vaccination but wants to get it eventually, once her antibody levels start to wane. The 37-year-old Muscovite told AP:

As long as my antibody titers are high, I have protection from the virus, and there is no point in getting injected with more protection on top of it.

High-profile officials, like Kremlin spokesman Dmitry Peskov and Valentina Matviyenko, speaker of the upper house of parliament, both have been quoted as saying they didn’t need to get vaccinated due to having high levels of antibodies, but they eventually decided to get their shots.

Contradicting guidelines may have contributed to Russia’s low vaccination rate, said Dr Anastasia Vasilyeva, leader of the Alliance of Doctors union. She said:

People don’t understand (what to do), because they’re constantly given different versions” of recommendations.

Even though Russia boasted of creating the world’s first vaccine, Sputnik V, only 32.5% of its 146 million people have gotten at least one shot, and only 28% are fully vaccinated. Critics have principally blamed a botched vaccine rollout and mixed messages the authorities have been sending about the outbreak.

Dr Simon Clarke, an associate professor in cellular microbiology at the University of Reading in England, said antibody tests shouldn’t influence any health-related decisions.

Getting an antibody test “is for your own personal satisfaction and curiosity,” he added.

Barchuk, the St. Petersburg epidemiologist, echoed his sentiment, saying there are too many gaps in understanding how antibodies work, and the tests offer little information beyond past infection.

But some Russian regions disregarded that advice, using positive antibody tests to allow people access to restaurants, bars and other public places on par with a vaccination certificate or a negative coronavirus test. Some people get an antibody test before or after vaccination to make sure the shot worked or see if they need a booster.

Dr Vasily Vlassov, an epidemiologist and a public health expert with the Higher School of Economics, says this attitude reflects Russians’ distrust of the state-run health care system and their struggle to navigate the confusion amid the pandemic. He said:

People’s attempt to find a rational way of acting, to base their decision on something, for example the antibodies, is understandable — the situation is difficult and bewildering. And they opt for a method that’s available for them rather than for a good one. Because there is no good method to make sure that you have immunity.
