Russia’s Putin tests experimental intranasal COVID-19 vaccine


Putin also received a Russian-made Sputnik light booster on Sunday, six months after his second dose of Sputnik V.

After receiving the booster shot, Putin voluntarily participated in a trial of an intranasal vaccine developed by the Gamalea Center, the maker of Sputnik V and later the single-dose Sputnik Light, he said in a televised meeting with government members.

Putin said he “felt nothing” after the intranasal vaccination. “Today, after these two procedures – injection and nasal form, the second part – I already went in for sports this morning. So I can testify that everything is developing the way our scientists say, ‘ he told the ministers.

In mid-October, the Russian Health Ministry approved clinical trials of the nasal spray form of the Sputnik V vaccine developed by the Gamalaya Center, according to RIA Novosti.

According to Denis Logunov, deputy director of Gamleya, Gamleya is still testing the efficacy of the nasal vaccine. “I must admit that this is an off-label administration, as always, we are testing it on our employees,” Logunov told Putin in a televised conversation after giving the booster on Sunday. Putin responded by asking Logunov if he could “participate in this experiment.”

Logunov said the intranasal form was developed to “induce barrier immunity,” which, with COVID-19, “refers to our immune organs located in the nose and pharynx.”

“We also know that vaccines administered via the parenteral method, or intramuscular injection, are effective, but they have limited ability to induce immunity from so-called breakthrough infection and symptomatic disease. We need to induce barrier immunity to mucous membranes. agent is required to be distributed through

According to Logunov, the nasal vaccine “just needs to be finalized a little bit, then it will go into clinical trials, and after that, we definitely plan to start rolling out new vaccines.” It is “convenient, painless, with absolute minimum side effects,” he said.
