Rhode Island health officials said the state is not receiving enough supply of the COVID-19 vaccine to meet President Joseph Biden’s goal of making all adults eligible to be vaccinated by May.

Concerns about Rhode Island’s ability to meet the president’s goal are based on the state’s projected supply and current demand presented during a meeting Tuesday morning of the COVID-19 Vaccine Subcommittee. 

The state’s projected timeline -- which shows all adults eligible to be vaccinated in June -- “is under heavy discussion,’’ Alysia Mihalakos, chief of the state Health Department’s Center for Emergency Preparedness and Response, said at the meeting. Though the current projections do not show the state having enough vaccines to meet the president’s goal, she said, “we would love to be pleasantly surprised.’’

Health officials said the biggest variable in the state’s vaccine supply is the Johnson & Johnson vaccine. The state received an initial 9,100 doses of the Johnson & Johnson single-shot vaccines in March, and health officials said they expect to receive another 1,300 doses this week. State health officials said they anticipated the supply will eventually increase to about 16,000 doses per week.

One reason for the projected shortage is the relatively high rate of vaccine uptake among eligible Rhode Islanders compared with other states. State health officials project that about 70% of residents in each eligibility group will be vaccinated. And they said demand for the vaccine continues to be high. During the last week, for example, the number of residents ages 65 to 74 who were vaccinated increased 50%.
