In Christmases gone by, professional Santas around the world generally offered nothing more than festive greetings and a sackful of presents.
But this year, Santa's Russian equivalent, Father Frost, is peddling an unusual bonus gift: a promise that he has anti-bodies to Covid-19.
With the festive season approaching, Russians who earn a living playing the part of Father Frost are facing lean prospects because of Covid restrictions.
Some are now advertising their services as "Father Frost with antibodies", in the hope that Russian families will hire them for a home visit.
