The decision this week by the Centers for Disease Control and the state’s Department of Public Health to halt administration of the Johnson & Johnson Covid-19 vaccine could put more strain on state supplies of other vaccines by Moderna and Pfizer, as clinics look to shift vaccination plans.
Since March 1, over 305,000 J&J doses have been delivered to the state, according to state data. As of April 12, more than half of those doses — 181,034 — had been administered here, according to state officials.
Further distribution plans were halted on Tuesday due to a rare blood clotting condition reported in six cases of the 6.8 million doses that have been administered nationwide. None of the cases reported were linked to Massachusetts.
