Starting this week, more coronavirus vaccines will be allocated to people receiving their second dose of the vaccine than those getting their first, according to officials.

Over the past several weeks, the number of first doses being administered has increased, which means a greater number of second doses are coming due, according to the Illinois Department of Public Health. With federal vaccine supplies limited, that means fewer people will receive their first dose.

Both the Moderna and Pfizer vaccines require a second dose in order to be up to 95% effective. Second doses need to be administered within four weeks after the first dose of the Moderna vaccine and within three weeks for those who receive the Pfizer vaccine.

State health officials anticipate these allocations will remain in place for the next several weeks based on federal projections of vaccine shipments. Officials say allocations for first doses can increase again in March.

As of Friday, more than 1.7 million vaccine doses have been administered statewide, with 3.25% of the population fully vaccinated, according to IDPH vaccine data.
