A monorail car rolls near a gait billboard reading “You're over 60! Get vaccinated immediately!” in Moscow, Russia, Sunday, April 4, 2021. To boost the demand, officials in Moscow this week started offering 1,000-ruble ($13) coupons to people over 60 for getting vaccinated. So far, the incentive hasn't elicited a lot of enthusiasm among elderly Muscovites. While some told the AP the initiative was helpful for those living off a relatively small pension, others complained about difficulties registering online to get the coupons or finding grocery stores where they could be used.

An employee stand waiting for customers at a vaccination point in Moscow, Russia, Wednesday, April 7, 2021. The low vaccine uptake hinges on several factors. Russian drug makers have been slow to ramp up mass production of the vaccine, leading to shortages in many regions last month. As more shots became available, people's unwillingness to get them emerged as another apparent problem. So far only 27.9 million two-dose sets have been produced, and only 15 million have been released into circulation after undergoing quality control. (Photo by Pavel Golovkin/AP Photo)
