Spain authorises booster COVID-19 shots for severely immunocompromised people

MADRID - Spain's healthcare regulator approved on Tuesday a third dose of COVID-19 vaccines for people with severely compromised immune systems who are likely to have weaker protection from the conventional two-dose inoculation schemes.

The so-called booster shot should be administered 28 days after the previous one in some cases, and preferably the same type of vaccine is to be used, the Public Health Commission said in a statement. It would not say how many people could get such shots. The authority reiterated that there are no solid data available to recommend administering booster shots to the general population.
