Nearly 2,000 doses of the coronavirus vaccine spoiled this week at the Jamaica Plain VA Medical Center in Boston, a spokesperson confirmed, at a time when vaccine doses coming to Massachusetts are down 73%.
The Veterans Affairs Boston Pharmacy staff on Tuesday found out that a freezer at the Jamaica Plain campus failed, ruining 1,900 doses of Moderna's COVID-19 vaccine.

A plug was loose after a contractor "accidentally removed it while cleaning," according to the VA spokesperson. The freezer was in "a secure location" and had an alarm system installed.
An investigation is underway to determine the cause of the incident and why the monitoring and alarm system didn't work. Replenishment doses are in process, the spokesperson said, and the VA does not "foresee disruption of our vaccination effort."
But the number of doses shipped to the Bay State is down this week by 73%, according to the Department of Public Health, with only 52,225 doses coming in to the commonwealth.
The latest vaccine report from the state shows that 86,230 doses were given this week, for a total of 359,919 doses in all. The report no longer breaks down the data by first and second dose.
Thursday's report did note the arrival of 157,300 Moderna doses on Jan. 12 that wasn't included in last week's report.
The pace that vaccines are being administered dropped by 24% in the weeklong period covered by Thursday's report, Jan. 13-19, compared to the week before.
The two coronavirus vaccines approved so far in the country's fight against the pandemic, from Pfizer and Cambridge-based Moderna, both require that people receive two doses, which are recommended to be spaced out over three or four weeks.
President Joe Biden outlined his plan to ramp up vaccinations across the U.S. Thursday, vowing "help is on the way."
Vaccines are the key to getting society back to normal, since they have been found to offer the greatest protection from serious complications in people who are infected with the virus. The widespread distribution of the vaccines will trigger the final phase in Massachusetts' reopening plan, when restrictions will be lifted.
