As explained by the Deputy Minister of justice Denis Novak, quoted by RIA Novosti, the proposed rule would not apply to those who refuse vaccination for any reasons of their own.

the Administrative responsibility is expected to occur in the case when there is an obligation to carry out these measures in accordance with the law on sanitary-epidemiological control. These include visits to countries with unfavourable epidemiological situation – before these trips to be vaccinated should be mandatory. Thus, if a citizen will go, for example, in some African country without mandatory vaccinations, it should be fine.
