Getting vaccinated to limit infections: The vaccines for coronavirus are effective and safe. All HMOs have them available.

Fourth Vaccine Dose

According to studies, the Omicron variant, which led to the current infection wave, causes reduced immune protection among vaccinated individuals as well, compared to other variants.
In light of the extensive infection rate and the enormity of infection cases, hospitalization cases and severe illness cases, it was decided to allow the fourth vaccination of anyone aged 18 and older who has pre-existing conditions and risk factors for severe COVID-19 illness, for their caregivers and for anyone else at high risk for exposure to a confirmed COVID-19 patient in their line of work.
Studies show that those vaccinated with the fourth vaccine are twice as protected against infection than those vaccinated with three doses, and 3 to 5 times better protected from severe illness compared to those vaccinated with three doses.

The type of vaccine administered in the fourth vaccination

It is preferable to administer a fourth dose of a mRNA-based vaccine (namely, the vaccines by Pfizer or Moderna), preferably a vaccine from the same Manufacturer of the first three doses. However, the fourth vaccine dose can also be administered with the AstraZeneca vaccine.

The fourth vaccine will be administered at the similar dosage as the third vaccine, save for the Moderna vaccine that will be administered at half the dosage (similar to the third dose by Moderna, subject to the Manufacturer's indications).
