Local governments and technology companies are scrambling to fix the glitch-filled registration portals that have slowed down the distribution of the coronavirus vaccine.

Washington, D.C.’s sign-up system has attracted significant attention over its failures. For several weeks in a row, residents have been greeted with glitches, failed captcha codes and system errors when trying to schedule appointments to get a potentially life-saving dose.

“The failures in D.C.’s vaccine distribution system have been painful for our residents,” D.C. Councilmember Janeese Lewis George (D) told The Hill.

D.C.’s vaccine portal is not unique in its technical failures. But across the country, there are signs of improvement as new systems launch and volunteers step up. Government officials see signs of hope just in time for more vaccines to become available and states to lower eligibility requirements.
