Hope the updated Sino versions for omicron will be available by the 2nd half of 2022.

And WHO approval of non-mRNA nasal vaccines too as it will provide further protection.
Putin had his nasal "sniff" last Nov and I believe Xi also had his since both met in Beijing recently w/o mask on.

The nasal formula was developed by Moscow’s Gamaleya Institute and is based on the country’s flagship Sputnik V vaccine. The institute’s head of microbiology, Denis Logunov, revealed that early research shows it could decrease the chances of infection, at a meeting with Putin on Sunday.

According to him, the use of the nasal version “is a convenient way to deliver a vaccine – it is painless, with an absolute minimum of side effects.”

Logunov went on to say that “after primary vaccination [by injection], you have systemic immunity, but after additional intranasal immunization, you create an additional immune barrier in the upper respiratory tract.”

Studies of the formula are expected to be conducted into 2022, he added.
