“Israel has among the highest coronavirus vaccination rates in the world, thanks to its early procurement of large quantities of Pfizer vaccine against COVID-19, but on Wednesday, the Health Ministry announced that the country’s four HMOs would be provided with vaccine produced by Massachusetts-based Moderna and that inoculations with the Moderna vaccine would begin on August 1.
The Pfizer vaccine will now only be administered to patients between the age of 12 and 18 and for second doses of the vaccine. Unlike the two doses of the Pfizer vaccine, which are administered 21 days apart, the Moderna vaccine is given 28 days apart.”
