As per them, a lot more research is needed before the older generation, or the younger crowd is enrolled for vaccine inoculation. Vladimir Bondarev, head of the Russian health ministry, in his most recent briefing added that older people would be given the jab once any shortcomings are rooted out in post registration clinical trials:

“In Russia, it is customary to certify [vaccines for] children from birth to 18 years old; adults from 18 to 60 years old; and older people — over 60 years old. Clinical studies have now been carried out on a group of volunteers aged from 18 to 60 years old. Thus, this vaccine is now indicated for use in people from 18 to 60 years old.”
